Özet
Thermoresponsive polymeric colloids attract great attention in several biotechnological applications owing to their ability to manipulate drug release characteristics in a controlled manner. Majority of these applications utilized N-isopropylacrylamide (NIPAM)-based particles for controlled drug release. Despite its advantages, such as easy chemical modification and well-documented literature, a potentially important bottleneck for NIPAM in biological applications is its tendency for nonspecific protein adsorption. Herein, we report a simple way to prepare novel thermoresponsive colloids composed of oligo(ethylene glycol) side chains via precipitation polymerization technique. In addition to displaying highly reversible thermal response, these particles also have considerably low nonspecific protein adsorption when compared with NIPAM counterparts. These crosslinked poly(ethylene glycol) ethyl ether methacrylate particles were characterized using dynamic light scattering and transmission electron microscopy. The effects of co-monomer, crosslinker and initiator on particle characteristics were investigated. Finally, particle toxicity studies were carried out using 3T3 fibroblast cell lines in MTT cytotoxicity assay. (C) 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 49: 4800-4808, 2011
