Abstract
With the constant need for surface sterilization to prevent bacterial contamination, easily applied, non-leaching, wash resistant and contact-killing coatings that not include copper or silver ions are the ideal solution to the problem of inhibiting bacterial growth. Herein catechol coatings utilizing Schiff-base grafting to a polyethyleneimine matrix are evaluated for their contact inhibition against S.aureus and E.coli bacteria and their performance after water and ethanol washes, comparing zone of inhibition on agar plates and the toxicity of leachates from water submerged coatings.Keywords
