Abstract Scope Over the last years there has been a renaissance of the use of copper for touch surfaces, as an effective weapon in the fight against infections caused by touch-transmitted, antibiotic resistant microbes. Products intended for contact with human skin, made from copper and its alloys, especially due to corrosive effect of human sweat, are prone to oxidation. It can lead to change in product appearance over time, which in turn gives rise to questions on the impact of human sweat-induced surface oxidation on antimicrobial efficacy of copper touch surfaces. Within our research samples of copper and some of its commercial alloys were subjected to oxidation in controlled laboratory conditions. Oxide layers were characterized in terms of its thickness, chemical composition, roughness and wettability. Research were completed with results of microbiological tests with common microbes. The project was financially supported by The Polish National Centre for Research and Development - PBS3/A9/32/2015
