Label-free detection of C-reactive protein using highly dispersible gold nanoparticles synthesized by reducible biomimetic block copolymers†
Abstract
Biomimetic block copolymer-protected gold nanoparticles (AuNPs) were prepared by autoreduction. Excellent colloidal stability of the AuNPs was observed at a high salt concentration and over a wide pH range. Functional AuNPs are useful for label-free detection of an inflammation biomarker, C-reactive protein (CRP).
