Laboratory of biosurfactants

The Team is located in lab. 330 (Old Chemistry Building). Its main focus is on phenomena occurring at phase boundaries: 1) surface activity of surfactants of natural origin (biosurfactants) and plant proteins in extracts obtained using green chemistry methods, without the use of organic solvents; 2) the effects of (bio)surfactants on model monolayers and bilayers imitating cell membranes, e.g. epidermal lipids (stratum corneum); 3) surface tension and surface rheology using the drop shape analysis method; 4) correlations between the structure of (bio)surfactants and their surface activity.
