Abstract

The stability of gold nanoparticles modified with heterobifunctional poly (ethylene glycol) (PEG) were investigated. An effective method for preparing hetero-bifunctional PEG by anionic ring-opening polymerization was also developed. Streptavidin-PEG gold nanoparticle showed extremely high response with biotinylated surface plasmon resonance (SPR) sensors. PEG-modified gold nanoparticles showed remarkable stability in physiological conditions, such as the solution of high ionic strength.
