Hetero-bifunctional Poly(ethylene glycol) Modified Gold Nanoparticles as an Intracellular Tracking and Delivery Agent

, , , , , , , , ,
To increase the targeting potential, circulation time, and the flexibility of surface-attached biomedically-relevant ligands on gold nanoparticles, hetero-bifunctional poly(ethylene glycol) (PEG, MW 1,500) was synthesized having a thiol group on one terminus and a reactive [...]
