Read The Rest.The general sterilization methods currently on the market mainly include ozone micro alcohol sterilization, ultraviolet irradiation sterilization, formaldehyde sterilization, and currently emerging hydrogen peroxide sterilization.

The above sterilization methods are used on various occasions, but the traditional Bacterial methods have fatal shortcomings in practical applications.

To overcome the problems caused by traditional sterilization methods: poor sterilization effect, high corrosiveness to equipment, and great harm to the human body, etc. First of all, hydrogen peroxide H2O2 is a naturally occurring chemical substance that exists widely in air and water. As early as the eighteenth century, humans discovered and started to use hydrogen peroxide, which is widely used in food, beverage, medical equipment, and health care.

The use of hydrogen peroxide depends mainly on the degree of oxidation, and different concentrations of hydrogen peroxide have different uses. In the case of wounds, pus, or dirt on the skin, mouth, and mucous membranes, it is immediately decomposed into oxygen. Oxygen does not combine with oxygen molecules and has a strong oxidizing ability.

When it comes into contact with bacteria, it can destroy the bacteria and kill them. The substances remaining after killing the bacteria are water and oxygen without any toxicity or irritation. No secondary pollution and drug resistance will occur.

Therefore, medical hydrogen peroxide is an ideal wound disinfectant. High concentration hydrogen peroxide is highly corrosive and has an explosion hazard. When liquid hydrogen peroxide is used for disinfection, high-concentration and long-term contact are required to kill highly resistant microorganisms such as bacterial spores and fungi. For example, when the 7.

In order to give utilize maximum advantages of hydrogen peroxide disinfection and sterilization no drug resistance and residueand to overcome its shortcomings of high concentration corrosivity, low concentration, low efficiency, etc. In the s, American researchers discovered for the first time that vaporized hydrogen peroxide has more than times the sterilization ability of liquid hydrogen peroxide.

In other words, hydrogen peroxide only needs a relatively low concentration in the gas phase to achieve the spore killing ability of high concentration liquid hydrogen peroxide. As a result, two different hydrogen peroxide gas disinfection and sterilization technologies have emerged:.

The following table shows the technical advantages of VHP sterilization system:. In this type of hydrogen peroxide sterilization, a special device is used, which is a dry-mist hydrogen peroxide sterilization device. Since the Vaporized Hydrogen Peroxide Sterilization equipment developed by the flash evaporation technology requires a high concentration of hydrogen peroxide, it is highly corrosive and expensive.

The scope of application is limited to the disinfection and sterilization of small anticorrosive enclosed spaces such as transfer cabins, isolators, freeze dryers, biological safety cabinets, medical equipment, biological incubators, and airlocks.

It is not suitable for disinfection and sterilization of GMP clean workshops, hospital operating rooms, and other large spaces. Because these small particles move irregularly in the air Brownian motion principlethey will not settle, nor will they aggregate to produce large droplets. They will rebound after contacting the surface of the object and will not decompose to make the surface wet.

dry hydrogen peroxide gas

Therefore, these characteristics of dry mist make it very diffusible, leaving no dead corners during disinfection, no wet surface, no corrosion of equipment, color steel plates, and walls. The results show that the smaller the atomized particles, the longer the suspension time in the air, and the greater the chance of full contact with bacteria in the air, to achieve the purpose of disinfection and sterilization. The following table compares the vaporized hydrogen peroxide sterilization system with traditional formaldehyde fumigation and ozone sterilization.

Hydrogen Peroxide Sterilization VS Traditional Sterilization The general sterilization methods currently on the market mainly include ozone micro alcohol sterilization, ultraviolet irradiation sterilization, formaldehyde sterilization, and currently emerging hydrogen peroxide sterilization. Hydrogen Peroxide, A Potent Disinfectant First of all, hydrogen peroxide H2O2 is a naturally occurring chemical substance that exists widely in air and water.

Vaporized Hydrogen Peroxide In order to give utilize maximum advantages of hydrogen peroxide disinfection and sterilization no drug resistance and residueand to overcome its shortcomings of high concentration corrosivity, low concentration, low efficiency, etc. You can check the AAMI TIR17 technical standard Dry-mist Hydrogen Peroxide Sterilization In this type of hydrogen peroxide sterilization, a special device is used, which is a dry-mist hydrogen peroxide sterilization device.

Project Dry-mist Hydrogen Peroxide Sterilization System Formaldehyde Fumigation Ozone Residue Basically, zero residue on surface space White crystals need to be cleaned after the sterilization process, and the residue is difficult to completely remove The residue needs to be removed, and it is equally difficult to remove it completely Chemical toxicity Hydrogen peroxide is non-toxic Carcinogenic EPA does not certify the strong oxidation and the harm of human respiratory system Disinfection effect Log4-log6 broad-spectrum sterilization effect, such as spores, fungi, etc.

Cannot fully achieve the log4-log6 spore killing effect At high concentration, it has spore killing effect, but due to the rapid cracking, it is difficult to achieve spore killing effect in a clean room Overall sterilization time hours At least 2 days Most users use the daily operation method, which is a potential hazard to the compatibility of the clean room environment.An improved poultry production method comprising providing dry hydrogen peroxide DHP to poultry eggs, chicks and birds, and devices for providing DHP to poultry production during laying, incubating, hatching, and growing.

In the U. There were hatcheries in the US with capacity of over million eggs per month. Duringmore than 11 billion broiler eggs were set for incubation in hatcheries to yield about 9. Of the 9. Poultry, primarily chickens but also including significant numbers of turkeys, quail, duck, and pheasant, are raised for a variety of reasons.

Most poultry is raised for meat and eggs and is supported by a breeding and egg production backend for the continual replacement of layers and broilers. In addition to food production, poultry is also raised and kept as pets. In addition to providing eggs for hatching broilers and layers, eggs are used for table consumption and, importantly, vaccine production.

In each situation, there is a need to reduce pathogens of all sorts. As shown in FIG. The breeder farms produce fertilized eggs that are provided to hatcheries to produce chicks that are in turn destined to be raised as layers for egg production and broilers.

These breeder farms also provide eggs for hatching and raising by small private farmers and individuals to raise their own chickens and eggs as well as serve as pets. Egg farms maintain laying hens as well as some roosters and primarily produce eggs for table consumption and eggs for hatcheries for production of meat e.

Specialized egg farms produce eggs for vaccine production. Modern poultry production methods generally are vertically integrated systems that include a feed mill which combines corn, soybean meal, and other ingredients, and provides the meal to the breeder farms, grow-out farms, and laying farms.

At each stage of the breeding process, whether for broilers meat or for egg laying, the population is expanded from to fold. Often, the facilities and processes downstream of the primary breeders are integrated within a single producer and geographical area. Grow-out farms are often contracted by the integrated producer.

Primary breeder companies maintain flocks of inbred lines and provide breeder chicks to breeder farms from great-grandparent eggs. A single male and 10 females can produce about great-grandparent stock birds GGP. The GGP birds are bred to produce about 7, grandparent GP birds that in turn produceor so parent stock birds. Parent stock birds in turn produce about 48, eggs for broiler production about fold expansion. Breeder farms produce hatching eggs that are transported to the hatchery.

After hatching, chicks are graded and sorted and sent to grow-out farms for the production of broilers.

Finally, the broilers are sent to processing plants for slaughter, processing, and packaging.Next generation devices contain highly sensitive metal alloys which cannot be exposed to high temperatures. Traditional water ALD is unreactive or too slow at moderate temperatures. Methods involving ozone or oxygen plasma are overly aggressive and damage the surface. A new oxidant is needed which shows good reactivity GPC and deposits high quality oxides without adverse effects.

Due to physical limitations on Si, SiGe is the leading channel material candidate for next generation devices. High quality, thin, low defect density interface layers are required to retain semiconductor mobility. Traditional methods, such as water, ozone and O2 plasma, damage SiGe surfaces and generate poor electrical properties. Area Selective Deposition requires intricate monolayers be deposited on a complex nanostructure without reacting or contaminating protecting groups on adjacent surfaces.

Ozone will react with adjacent structures.

Tests with aluminum and silicon precursors show that hydrogen peroxide is more reactive at low temperatures. High quality oxide films may be deposited with use of a minimal chemistry consumed.

When delivered ultra dry, Hydrogen peroxide gas can directly react with metal precursors as water no longer interferes with reaction kinetics. Hydrogen peroxide readily breaks into OH groups that efficiently attach to deposition surfaces.

Nucleation density is improved 5x on SiGe and over 3x on germanium versus water. This leads to shorter ALD incubation periods and few interfacial defects on the resulting oxide films. Anhydrous peroxide HOOH readily splits into OH radicals, ensuring a high concentration of -OH groups on the surface that serves as a large diffusion barrier.

It is difficult for additional HOOH to penetrate this barrier. Composition and high k values are equivalent to those grown by optimized Ozone ALD without the adverse effect of ozone on surfaces. BRUTE Peroxide delivers hydrogen peroxide gas into a wide range of process conditions from vacuum to atmospheric pressure. Hydrogen peroxide vapor pressure ranges from 0.

BRUTE Peroxide includes a vaporizer preloaded with a proprietary non-volatile solvent that ensures safety. Hydrogen peroxide diffuses across a proprietary membrane assembly, leaving the solvent behind. Once across the membrane, hydrogen peroxide is swept to process by a carrier gas or diffuses via vacuum conditions.

Hydrogen peroxide vapor pressure is 0. BRUTE Peroxide generates ultra-dry hydrogen peroxide gas and can be used with or without a carrier gas. In order to minimize defects, enhance uniformity and increase device performance, researchers have begun to focus on the interface between dielectric materials and Si, SiGe, Ge and InGaAs. Most defects, which lead to charge traps and decreased mobility, are believed to occur in this interfacial region.

While cartoons of ALD show nice monolayer continuous growth, ALD growth usually occurs in islands on the surface with 3 cycles typically needed for each monolayer. More surprising is that initiation of ALD growth on the surface is far from ideal. Initial film growth of the first monolayer may take up to cycles. Research suggests that significant device improvements can be made if the surface is functionalized with a dense layer of hydroxyl groups —OH, prior to deposition.

Area selective deposition is becoming increasingly important for the immense scaling effort continuously taking place in the semiconductor industry for Logic and Memory Devices. Beyond that in a joint effort the researchers and the industry are looking for alternative patterning methods and many of them are based on so called bottom-up patterning. Low temperature Oxide ALD Next generation devices contain highly sensitive metal alloys which cannot be exposed to high temperatures.

Passivation Layers Due to physical limitations on Si, SiGe is the leading channel material candidate for next generation devices. Area Selective Deposition Area Selective Deposition requires intricate monolayers be deposited on a complex nanostructure without reacting or contaminating protecting groups on adjacent surfaces.

Low Temperature Oxide Growth Tests with aluminum and silicon precursors show that hydrogen peroxide is more reactive at low temperatures. High Nucleation Density Hydrogen peroxide readily breaks into OH groups that efficiently attach to deposition surfaces.It is widely acknowledged that contaminated surfaces, particularly those that are high-tough or high-use, pose an infection transmission risk in healthcare facilities.

Additionally, studies over the past decade have demonstrated that traditional healthcare facility environmental cleaning and microbial reduction methods are inadequate, particularly in the face of rising numbers of antimicrobial resistant organisms.

Even with these advancements, some significant challenges remain. The vast majority of these efforts have centered around terminal cleaning of patient rooms. Furthermore, many of the effective automated microbial reduction systems can only be employed in an unoccupied room, presenting logistical challenges to healthcare facilities with high volumes and, thus, the need for rapid room turnover.

Modern microbial reduction strategies: Manual cleaning, antimicrobial surfaces, automated systems. The benefit of manual cleaning is that a rapid effect can be achieved without capital equipment expenditures. The drawbacks, however, include the fact that it is labor intensive and the efficacy is dependent on compliance with protocol and thoroughnesstwo factors that have been demonstrated in studies to be widely variable and often suboptimal.

Additionally, manual cleaning is obviously an intermittent solution to what is inherently a continuous problem and does not address airborne contamination. Antimicrobial surfaces, in which equipment ranging from counter-tops to privacy curtains are impregnated with molecules such as copper or silver that possess antimicrobial properties, have become an increasingly popular environmental microbial reduction strategy as they provide a continuous effect with no increased labor requirements.

More importantly, it is unclear what the long-term antimicrobial potency and cost-effectiveness of these surfaces are. Automated systems, utilizing ultraviolet radiation or vaporized agents, arguably represent the biggest area of growth in environmental microbial reduction efforts. However, these systems ultraviolet radiation and vaporized hydrogen peroxidepose a risk to humans and thus can only be utilized in unoccupied spaces, representing a logistical challenge to high-turnover facilities.

Like manual cleaning, they are an intermittent microbial reduction solution, and like antimicrobial surfaces, they require a significant capital expenditure. Tackling microbial reduction challenges with a novel application of an existing technology: Dry hydrogen peroxide. The biocidal activity of hydrogen peroxide in any form — liquid, vapor, dry gas — is rooted in the fact that microbes require water and have electrostatically charged points on their cells designed to attract water molecules from the environment.

This explains why commercially available hydrogen peroxide vapor systems utilizing a vaporized mixture of water and hydrogen peroxide cannot be used in occupied spaces as their hydrogen peroxide concentrations exceed acceptable safety limits for human exposure established by the Occupational Safety and Health Administration OSHA.

Furthermore, unlike aqueous forms of hydrogen peroxide, including vapors, that are acidic because of the chemical properties associated with mixing hydrogen peroxide and water, dry hydrogen peroxide gas does not damage surfaces in a room.

Therefore, the integrity of surfaces ranging from those of electronic monitoring devices to soft privacy curtain are not compromised. Thus, the challenges of compliance, comprehensive microbial reduction, and disruption to patient throughput are eliminated.

Additionally, because continuous microbial reduction provided by DHP reduces the steady state of environmental contamination, standard intermittent adjunctive cleaning interventions address a much lower bioburden and is therefore more effective.

Rutala award for best abstract on the subject of disinfection, sterilization, or antisepsis in To create a baseline, researchers took culture samples from hospital rooms and common work areas within the unit before and after standard hospital cleaning. Among the most notable findings were the complete eradication of Staphylococcus aureus, Candida parapsilosis, Pseudomonas putida, Flavobacterium meningosepticum, Pseudomonas picketti, and Citrobacter spp.

Reducing environmental contamination in an effort to mitigate infection transmission has long been a top priority for healthcare facilities. It is a challenge that is heightened by the extended survival times many pathogens, including multidrug-resistant organisms, have on hard surfaces. Does it provide continuous microbial reduction thereby mitigating the inevitable risk of recontamination? Does it impact our patient throughput?

Is it safe for healthcare workers and patients alike? Is it comprehensive? Is it cost-effective?A hydrogen peroxide sterilization cycle typically requires less time than alternative forms of sterilization, such as ethylene oxide sterilization.

A hydrogen peroxide sterilization process involves H 2 O 2 vapor filling the sterilizer chamber, contacting and sterilizing exposed device surfaces. Once the sterilization cycle has completed, the vapor is vacuumed from the chamber and converted to water and oxygen.

Low temperature sterilization is a sterilization process best used for heat-sensitive devices that may be damaged by the conditions of a steam sterilization cycle. Ethylene oxide EO and vaporized hydrogen peroxide VHP are the two most common types of low temperature sterilization. Unlike heat-stable instruments, heat and moisture-sensitive devices are not always compatible with all models of low temperature sterilizers. Hydrogen peroxide sterilization is also known as vaporized hydrogen peroxide sterilization or VHP.

Healthcare facilities more commonly choose vaporized hydrogen peroxide sterilization over ethylene oxide sterilization as their low temperature sterilization system. This preference for VHP is reflected by the declining use of ethylene oxide sterilization systems in hospitals.

The familiarity of hydrogen peroxide in households provides users a sense of confidence with hydrogen peroxide as a non-toxic, environmentally safe solution.

No ventilation is necessary for the vaporized hydrogen peroxide sterilization process and VHP machines only utilize one utility — power. No extra water, steam, or compressed air utilities are necessary.
