Abstract
Polar coatings are used to protect surfaces from marine fouling based on the formation of a hydrated surface layer, which acts as a barrier to marine microorganisms. In this context, we have developed a material with glucose bound to ferrocene to prevent surface absorption. Glucose brings the polarity while ferrocene has the role of varying the state of charge of the surface. We therefore describe the synthesis of 6-deoxy-6-(4-ferrocenyl-1H-1,2,3-triazol-1-yl)-1-(4-aminophenyl)-beta-D-glucopyranose 6 and its immobilization on the surface of a C electrode and develop a methodology used for antibacterial testing. We were able to demonstrate that the immobilization of glucose 6 could be done in an artificial seawater environment by oxidation of an amine. The use of a 96-microwell platform equipped with electrodes for cyclic voltammetry, linked to a potentiostat, allowed the electrical solicitation of the coating in the presence of marine bacteria with a greater number of biological replicates. We have shown that the coating has an antibacterial effect, and this effect is accentuated when the coating is electrically stressed, resulting in the appearance and disappearance of charge on ferrocene, a phenomenon that seems to be conducive to colonization by bacteria.This publication has 38 references indexed in Scilit:
