A method for reducing the risk of infections in humans and animals by removing dangerous microorganisms from flat surfaces with cold plasma, has ben developed and patented by scientists from the University of Gdańsk, the Medical University of Gdańsk, and the Wrocław University of Science and Technology.
According to the scientists, the method effectively eliminates microorganisms that cause skin infections in humans and animals, including Staphylococcus aureus, Staphylococcus epidermidis, Candida albicans, and Dermatophilus congolensis.
The technology can be used to sterilise surfaces in hospitals, laboratories, and breeding areas.
The solution is based on cold atmospheric pressure plasma (CAPP), generated in the form of a dielectric barrier discharge (DBD). The invention is patented in Europe (EPO) and Poland, enabling its wider implementation.
'The invention effectively eliminates microorganisms from surfaces, which are often a source of infections', says Wojciech Śledź, PhD, from the University of Gdańsk. He adds that difficult-to-heal wounds in humans and animals, especially those infected with multidrug-resistant strains of bacteria, significantly reduce quality of life and complicate treatment.
'Barrier discharges generate reactive oxygen and nitrogen species and UV radiation, which effectively destroy microorganisms and hinder their ability to develop immunity', adds Agata Motyka-Pomagruk, PhD, from the University of Gdańsk.
The technology has been laboratory tested and the scientists are now searching for partners to commercialise it. Intellectual property protection processes were coordinated by specialists from the University of Gdańsk Technology Transfer Office. (PAP)
