Abstract

Urinary polyurethane (PU) and silicone (SI) catheters were coated with poly(catechin) to reduce bacterial adhesion. Laccase was used as a biocatalyst to oxidize the catechin monomer and produce the polymer. Optimization of the catheter surface functionalization followed two different approaches: with or without previous alkali treatment. The results indicated higher levels of polymer attachment for the alkali-treated catheters ( 18% for PU and  33% for SI catheters). The reduction of biofilm formation on the catheter surface was quantitatively evaluated under static adhesion conditions again ...
