Title

Effect of polystyrene particles on the properties of model biological membranes

Abstract

Biological membranes are the first barrier encountered by particles foreign to the cell. Characterizing the interaction of plastic nanoparticles (NPs) and polymers with cell membranes is the first step towards understanding the physical and chemical basis for their toxicity in all living organisms. Recently we found that doping doses of short chains of polystyrene (25 monomers) alter the thermal and structural properties of DPPC model membranes, in a concentration-dependent fashion. Our aim is to study the interaction of polystyrene with increasing chain-length with different biomimetic model membranes by neutron reflectometry to investigate the disposition of polymer chains in the lipid core as a function of their length and mole fraction.
