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.

Application

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.
Used to prepare thiol-functionalized 1.5 nm gold nanoparticles via a ligand exchange process with triphenylphosphine-stabilized nanoparticles. This compound is used in self-assembly to produce hydrophilic SAMs. The resulting monolayers which are terminated with carboxylic acids can be further functionalized with various amines and alcohols to introduce more complex end groups. Can also be used to control the rate of aggregation of gold colloidal nanoparticles using pH.

Inorganic nanomaterials are tunable by size, shape, structure, and/or composition. Advances in the synthesis of well-defined nanomaterials have enabled control over their unique optical, electronic, and chemical properties stimulating tremendous interest across a wide range of disciplines. This article illuminates some of the recent research advances of inorganic nanoparticles (NPs) in optoelectronics applications.

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold).

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
