5-CARBOXY-1-PENTANETHIOL Chemical Properties,Usage,Production

Chemical Properties

Colorless to yellow liquid

Uses

MHA can be used in the surface modification of InP quantum nanowires for their potential uage in fluorescent chemical sensors that monitor cyanide ions. MHA may also be covalently bonded with liposomes that can form a SAM on the surface of gold for use as an insect odorant receptor in biosensor based applications.

General Description

6-Mercaptohexanoic acid (MHA) forms a self-assembled monolayer (SAM) that is used to cap a variety of materials like gold nanoparticles (AuNPs) and indium phosphide quantum dots (InPQDs). It is majorly used in immobilizing the surface molecules, which enhance the physio-chemical and electrical properties.
