Formation and physicochemical properties of glycogen phosphorylase in complex with a cationic polyelectrolyte

Rational design of dual-functional surfaces on polypropylene with antifouling and antibacterial performances via a micropatterning strategy

“…One is because the surface of the micropattern sample has good hydrophilicity, the other is because the cationic polyelectrolyte QPDMAEMA shows a strong positive charge and is located at the top layer of the surface, it will first interact with the negatively charged phosphatide bimolecular layer in the bacterial cytomembrane to rupture the bacterial cytomembrane and kill the bacteria. 63,64 The similar sterilization rates of around 95% were also obtained for the patterned PP-QPDMAEMA-PMPC against S. aureus and E. coli (Fig. 8D).…”
