Necessity is the Mother of Invention

Grzegorz Gorczyca, a postgraduate biotechnology student at the Gdańsk University of Technology, is another young Polish inventor who has developed a new-generation wound dressing to help treat wounds that are particularly hard to heal.

Gorczyca invented the dressing to avoid excessive treatment costs for his lingering arm wound infected with the potentially dangerous Staphylococcus aureus bacteria. Standard dressings which doctors put on Gorczyca’s arm proved ineffective in dealing with the bacteria.

As he searched for an alternative raw material to produce a cheap substitute for expensive wound dressings, the young researcher decided to use chitosan, a polysaccharide produced commercially through the chemical deacethylation of chitin.

Working on his project, Gorczyca received substantial support from experienced scientists including Prof. Sławomir Milewski at the Gdańsk University of Technology’s Department of Pharmaceutical Technology and Biochemistry.

The new type of dressing developed by Gorczyca features a unique combination of three natural polymers—chitosan, collagen and gelatin—and an inventive technology to produce sponge-like hydrogel dressings which destroy microbes. The dressing effectively absorbs matter exuded from wounds, which helps reduce bleeding and ensures the appropriate moisture level for the wound to heal. Gorczyca’s dressing is also a remarkable odor absorber, which is important because infected wounds tend to give off pungent and unpleasant smells. Such dressings are completely biodegradable.
