Nanogel receptors for high isoelectric point protein detection: influence of electrostatic and covalent polymer-protein interactions

Chem Commun (Camb). 2020 Jun 7;56(45):6141-6144. doi: 10.1039/d0cc02200d. Epub 2020 May 4.

Abstract

An aldehyde acrylate-based functional monomer was incorporated into poly(N-isopropylacrylamide-co-methacrylic acid) nanogels for use as protein receptors. The aldehyde component forms dynamic imines with surface exposed lysine residues, while carboxylic acid/carboxylate moieties form electrostatic interactions with high isoelectric point proteins. Together, these interactions effect protein adsorption and recognition.
