Abstract

A simple method was developed to fabricate nano-patterned protein layers on poly (lactic acid) (PLA) surface by dewetting method. It was found that nano-patterned protein layers were formed on PLA surface by slow drying in high humidity. The influence of wettability and viscoelastic properties of substrates were also investigated. As a result, typical spinodal dewetting patterns formed for BSA. However, network structures were obtained for collagen at acidic condition and well-oriented fibrils at neutral pH. It was attributed to dewetting on hydrophobic substrate as well as the plasticity and variety of collagen self-assemblies.
