A light sensitive self-assembled nanogel as a tecton for protein patterning materials†
Abstract
A self-assembled nanogel is constructed from light-sensitive cholesteryl pullulan (Ls-CHP) by using photo-labile ortho-nitrobenzyl (o-NB) units. The nanogel-based film is obtained by evaporation of an Ls-CHP nanogel solution. Exposure of the resulting nanogel-based film to light with a mask resulted in a patterned film that can encapsulate FITC-insulin.
