Effect of monolayer on nanoparticle-protein (ChT) interactions. a) Simple alkanethiol-based monolayer results in protein denaturation. b) TEG-functionalized particles are non-interacting. c) Termination of the TEG layer with carboxylate groups results in reversible binding to ChT that stabilizes the protein towards denaturation.
