Descripción

Application

Poly(ethylene glycol) methyl ether thiol can be used to functionalize Fe₃O₄@Au core-shell nanoparticles. The thiolated PEG increases the water solubility and significantly lowers the nanotoxicity.

It can be used as a precursor to synthesize PEG conjugated poly(β-amino ester) polyplexes for gene therapy.
