Antimicrobial Coatings

The science behind the research

Antimicrobial coatings have been widely investigated for different applications such as medical devices in clinics, self-cleaning coatings in industry, and linens and clothing at homes

Ongoing research

In our group, Ag based antimicrobial coatings have been deposited by non-vacuum vapour depositions methods. The coatings show very good antimicrobial properties and can be easily deposited on different substrates such as glass, paper, fibre and stainless steel at large area.

Recent studies have been focused on antimicrobial wound dressing based on bacterial cellulose (BC)/methylglyoxal (MGO) composites, inspired by naturally antimicrobial Manuka honey and produced with a dip-coating method. The membranes developed show a high thermal stability within the human body temperature range, as well as an increased tensile strength and a higher antimicrobial activity against different bacteria with increasing the BC/MGO v/v ratio in the range 0.04%-4%.
