Medical Technology

 

In the medical technology area, medical expertise and cold plasma technology are brought together. Plasmawise collaborates with physicians and healthcare professionals to explore new ideas and new solutions for both sick and healthy individuals who need treatment, rehabilitation and nursing to improve and innovate existing medical technology.

Questions & answers:

Can cold atmospheric plasma be used for sterilization?

Yes, our studies have shown that short plasma treatment of thermolabile equipment of a few minutes is capable of reducing Geobacillus stearothermophilus spores by about 99.9999%.

Can all type of surfaces be treated with cold plasma?

In theory, yes – however, in order to avoid damaging the treated surface, the plasma discharge need to be designed with specific design parameters.

Can all sorts of bacterial species be inactivated by cold atmospheric plasma?

Yes, research on cold plasma application on all type of bacteria has shown that there is no bacterial species with resistance towards cold plasma.

Can cold plasma be used to treat fine tubes and tiny cavities?

Due to its intrinsic properties, cold atmospheric plasma can be applied to fine tubes and tiny cavities when high flow velocities are used so that gaseous species can reach remote internal areas. Sterilization and disinfection of such areas are possible and have been experimented and validated in many applications such as dental and chirurgical instruments.

Can multidrug-resistant bacteria such as MRSA be inactivated by cold plasma?

Yes indeed, cold atmospheric plasma inactivates all sorts of bacteria regardless of their degree of resistance towards antibiotics.

Odour management

Odor control

 

In daily life, nuisance from odors deriving from livestock farming, gastronomy and traffic is a main concern to local authorities that are urged to tackle this issue. In order to limit odor emissions, a set of protection laws have been implemented in many countries. Odors can be effectively removed by cold atmospheric plasma and Plasmawise is developing new ways to deal with indoor and outdoor odor emissions.

Questions & answers:

Can Plasmawise technology be used on a large scale?

Plasmawise has first developed this technology with small units to be used for air treatment in homes and offices. Larger units, e.g. for treatment of exhaust air in large factories, are also available.

Can cold plasma eliminate all types of odors??

Yes. Covalent bonds which make up odors can be broken within the Electron-Impact-Dissociation process by the free electrons found in the plasma mixture. As a consequence, all sorts of odors can be eliminated such as smokes of cigarette, gastronomy odors and bathrooms environment. 

Is plasma odors elimination a long process?

No. Plasma processes are immediate as the effects can be observed within a few fractions of a second. The free electrons, being very reactive, interact with the molecules responsible for odours  immediately after the plasma discharge is started. The process behind this interaction is named Electron-Impact-Dissociation.

What makes Plasmawise technology unique when it come to treat industrial odours?

The existing technology found on the market has been developed with ozone being the main reaction process behind odour elimination and mainly works on air exhausts. Plasmawise technology takes advantage of the Electron-Impact-Dissociation process in addition to ozone and operates with air recirculation with cold plasma being in direct contact with air.

Water treatment

Water treatment

 

One of the key cold plasma technologies developed by Plasmawise is the treatment and disinfection of process waters. Among the main benefits of plasma technology beside disinfection of water are the destruction of organic pollutants and dissolved oil contaminants. Cold plasma applied to contaminated water is an ideal solution to remove residual color and odors leading to a highly colorless and fresh water.

Questions & answers:

Contaminated water treated by plasma can it become drinkable?

Yes. 99.9999%  of viruses and bacteria are inactivated by active species produced by cold atmospheric plasma in air and dissolved in water within few minutes of plasma treatment. Our studies have shown that water treated by our cold plasma technology complies with international guidelines for drinking water quality. 

Can cold plasma be used to remove dirt particles from water?

No. Cold plasma is not effective for the removal of dirt particles that may be found in water. Usually, cold plasma is combined with particle filter for this purpose.

Hygiene

Hygiene

 

Plasmawise along with its academic partners have identified poor hygiene as a very crucial threat to modern societies with the spear of contagious diseases. Therefore, a scheme to develop solutions using cold atmospheric plasma has been implemented during the past few years to tackle the issue of the continuous increase of viruses and bacteria.

Questions & answers:

What type of solutions in the area of hygiene cold atmospheric plasma can be implemented?

Hygienic problems caused either by microorganisms or by odors can be tackled by using a specific cold atmospheric plasma solution. Plasma discharges can be implemented either to treat items used for everyday hygiene practices such as toothbrushes, or integrated into household machines such dishwashers or vacuum cleaning machines. Plasma can be also implemented in an indirect fashion by treating water which can be used for hygiene application.

How plasma activated water (PAW) can be used for cleaning purposes?

In order to obtain plasma activated water (PAW), normal tap water is treated with a plasma discharge using ambient air. Plasma species produced in the water/air surface are transferred to the water content by dissolution and they play the role of bactericidal agents. 

How long does the plasma effect on water last?

Usually, plasma activated water (PAW) treated with ambient air becomes rich in dissolved nitrogen species and remain active for up to 7 days.

Air purification

Air purification

 

Modern life has brought people to spend much of their times indoors. Therefore, the indoor air quality has become increasingly important due to the emergence of issues related to odor discomfort and contamination by allergens and microorganisms. Cold atmospheric plasma and technologies developed by Plasmawise can tackle these issues by the elimination of a wide range of molecules and pollutants present in ambient indoor air providing healthier air to breathe.

Questions & answers:

What are the precise mecanisms behind pollutant removal by cold atmospheric plasma?

The underlying technology for air purification is the Magnetically Oriented Plasma Source technology (MOPS), which is based on the principle of electron impact dissociation. Pollutants interacting with the electrons generated by the plasma source are dissociated and thus rendered harmless. The various products of this reaction remain in the air and can be bound by combination with a filter system.

What are the target applications of this technology?

Offices at work by also homes can take advantage of this solution to treat indoor air. Aerospace and car industry are more and more attracted to implement this technology.
