Based on the understanding of the adhesion mechanisms of target organisms, we develop biocide-free bioactive antifouling surfaces. For example, as many fouling species use proteins and glycoprotein polymers to attach to surfaces, we explore strategies for the use of immobilized proteolytic enzymes to prevent marine biofouling. Investigations of the impact of the characteristics of the polymer films on the amount, conformation, availability function, and release of bioactive molecules; together with studies if the influence of bioactive compounds on cell adhesion will enable the rational design of surfaces with optimal antifouling properties.
