| 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. |
| 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. |
