terraplasma receives U.S. patent for Plasma Activated Water (PAW)

U.S. patent granted to terraplasma, the innovation leader in the development and implementation of cold atmospheric plasma (cold plasma for short) applications. The United States Trademark and Patent Office (USTPO) granted a patent under the number US 11,628,050B2 for the "Apparatus and method for treating objects, in particular teeth and dentures". The invention relates in detail to a device and method for treating, in particular cleaning objects (in particular dental objects and/or teeth) with so-called "Plasma Activated Water (PAW)".

This Plasma Activated Water (so named because of the scientifically detectable, short-lived reactive plasma species such as nitrogen and oxygen compounds) allows objects to be disinfected easily, safely and without the use of additional chemicals.

The handling of the terraplasmaWater prototype is very simple: the compact device is filled with normal tap water. After pressing the button, the air plasma generated in the device is blown into the water for one minute, creating Plasma Activated Water (PAW), which retains its effect for a few minutes and then returns to normal (disinfected) tap water. In this way, objects (such as braces or dentures) can be cleaned in the device itself or the Plasma Activated Water can be used as a sustainable mouth rinse. In addition to deactivating microorganisms, this mouth rinse also provides – when used several times – a gentle whitening effect of the teeth.

Oral hygiene without additional chemicals

Thanks to the mouthwash with PAW, a similar cleaning effect can be achieved as with conventional mouthwashes – but completely without the use of additional chemicals. The negative environmental impact of classically produced mouthwashes cannot be ignored: first, the chemicals for mouthwashes must be produced, stored, filled and finally transported to the point of sale in an energy-intensive process. After use, they end up in rivers or sewage treatment plants, where they disrupt the important interaction of many bacterial species, reducing the cleaning effect (in clarifiers or water bodies, for example).

Cold plasma is the future of disinfection

The application of cold plasma (or low-temperature plasma) is a novel technology for disinfection that can kill even antibiotic-resistant microorganisms at room temperature in a time-saving manner, not only on surfaces but also in water and even through clothing. This makes Cold Plasma suitable for disinfection of air, surfaces, objects, hand disinfection, but also for treatment of poorly healing chronic wounds. Cold plasma offers a large variety of different applications, which terraplasma is currently researching and implementing together with its partners.

Cold plasma: terraplasma shows sustainable innovations in Berlin and Munich

“replacing chemicals. the sustainable way.” Under this motto, the innovation leader from Garching near Munich promotes the many different possible uses of cold plasma technology. Cold plasma is perfect for replacing conventional disinfection solutions with chemicals, UV, heat or radiation, for example, and thus enables true sustainability. In order to be able to show this to as many interested customers as possible, terraplasma is going to several trade fairs this year.
