Descrizione generale

11-mercaptoundecanoic acid (MUA) has long alkane chains and carboxyl containing thiols that are highly packed and form a self-assembled monolayer (SAM). It modifies the surface of nanoparticles to facilitate their dispersion into water and solvent based mediums.

Applicazioni

MUA is used for the carboxylic acid functionalization of 1-dodecanethiol-protected gold nanoparticles (AuNPs) by Murray place-displacement reaction generally utilized in biomedical applications. It can also be used to modify the surface of platinum nanoparticles (PtNPs) by creating a ligand nano-assembly with a high surface coverage for use in surface-enhanced Raman spectroscopy (SERS). A single cell biochip platform can be developed utilizing a cell attachment technique with MUA forming a SAM that was attached to single cells. MUA may be used to prepare a tetrafluorophenyl-activated ester self-assembled monolayer to immobilize amine-modified oligonucleotides and DNA. It is also used to create 3D-assembled gold nanostructures for plasmonic biosensors.

Precise Nanoparticles for Optoelectronics Applications

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.

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

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.
