General description

Poly(ethylene glycol) methyl ether thiol (mPEGthiol) is a thiol-terminated biocompatible polymer widely used in the surfacefunctionalization of gold nanoparticles. Thiol moieties bind with high affinityto gold surfaces by forming a self-assembled monolayer (SAM) through thecovalent thiolate–metal bond. mPEG thiol-coated Au nanoparticles findapplication in the fields of biosensors and drug delivery systems.

Application

Poly(ethylene glycol) methyl ether thiol-coated Au nanoparticles can be used for the determination of melamine T. by an optical method. It can also be used to fabricate switchable super-wetting membranes foroil/water separation.

The use of conductive nanoparticles (NPs) was previously proposed as a way to locally amplify the electric field (EF) intensity at the cell membrane to enhance cell electroporation. To achieve this, a close distance between the NPs and the cell

Antibody-coated nanoparticles have recently attracted considerable attention, with the focus falling on diagnostics. Nevertheless, controlled antibody bioconjugation remains a challenge. Here, we present two strategies of bioconjugation with the aim of evaluating the best approach for the coupling of antibodies
