Superhydrophobic polypyrene films to prevent Staphylococcus aureus and Pseudomonas aeruginosa biofilm adhesion on surfaces: high efficiency deciphered by fluorescence microscopy.

Abstract

A blue luminescent and superhydrophobic coating based on electropolymerized fluorinated-pyrene monomer and its planktonic bacteria and biofilm repellent properties are reported. Two different pathogenic bacterial strains (gram-positive and gram-negative) at two different incubation times (2 h planktonic bacterial and 24 h biofilm adhesion) are studied and followed (analyzed) using multicolor scanning confocal fluorescence microscopy. The coating proves to reduce the bacterial adhesion by 65 %. It is highly effective against biofilm attachment with 90 % reduction of bacteria surface coverage. Such blue fluorescent surface provides an easy way to characterize the coating, observe the bacterial distribution and quantify the bacterial coverage rate by different color fluorescence imaging. Furthermore, the film does not show a significant bacterial toxicity during the worked incubation times.
