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

Degradable Poly(ethylene glycol) Hydrogels for 2D and 3D Cell Culture

Progress in biotechnology fields such as tissue engineering and drug delivery is accompanied by an increasing demand for diverse functional biomaterials. One class of biomaterials that has been the subject of intense research interest is hydrogels, because they closely mimic the natural environment of cells, both chemically and physically and therefore can be used as support to grow cells. This article specifically discusses poly(ethylene glycol) (PEG) hydrogels, which are good for biological applications because they do not generally elicit an immune response. PEGs offer a readily available, easy to modify polymer for widespread use in hydrogel fabrication, including 2D and 3D scaffold for tissue culture. The degradable linkages also enable a variety of applications for release of therapeutic agents.
