Abstract
Antimicrobial azo compounds include azobenzene monomers having a phenyl ring comprising a hydroxyl substituent group. The azobenzene monomers can be reacted with a polymeric material to form an antimicrobial coating that prevents growth of persistent biofilms. In some implementations, the azobenzene monomers can be used to coat the surface of a dental resin-based composite to prevent the formation secondary caries. In some implementations, the azobenzene coating can be used to disperse microbial biofilms through a photofluidization process (rapid photoisomerization) in addition to biochemically preventing formation of the microbial biofilm.
