In this work, longa term antibacterial, antiadhesion, and antibiofilm activities are afforded to industrial stainless steel surfaces following a green and bioa inspired strategy. Starting from catechol bearing synthetic polymers, the film crossa linking and the grafting of active (bio)molecules are possible under environmentally friendly conditions (in aqueous media and at room temperature). A bioa inspired polyelectrolyte, a polycationa bearing catechol, is used as the filma anchoring polymer while a poly(methacrylamide)a bearing quinone groups serves as the crossa linking agent in combination with a polymer bearing primary amine groups. The amine/quinone reaction is exploited to prepare stable solutions of nanogels in water at room temperature that can be easily deposited to stainless steel. This coating provides quinonea functionalized surfaces that are then used to covalently anchor active (bio)molecules (antibiofilm enzyme and antiadhesion polymer) through thiol/quinone reactions.
