Facile and material-independent fabrication of poly(luteolin) coatings and their unimpaired antibacterial activity against Staphylococcus aureus after steam sterilization treatments

Abstract

Poly(luteolin) coatings on different surfaces are fabricated via facile one-step autoxidation of luteolin in alkaline solution. They exhibit unimpaired antibacterial activities against Staphylococcus aureus even after high temperature steam sterilization treatments, which provides them with extra advantages for practical applications, e.g., in the field of implant materials and devices.
