Application

MDA can functionalize gold nanoparticles which can form screen printed electrodes for electrochemical detection. It can also form ligands with cadmium selenium (CdSe) quantum dots (ODs) which can be deposited on titanium oxide(TiO2) based films.
This compound is used to produce hydrophilic SAMs. The resulting monolayers which are terminated with carboxylic acids can be further functionalized to introduce more complex end groups. Used in a study of the effect of molecular structure on the precision of copper-bound α,ω-mercaptoalkanoic acid "molecular ruler" stacks.

General description

12-Mercaptododecanoic acid (MDA) is a carboxylic acid terminated thiol that forms self-assembled monolayers (SAMs) on a variety of surfaces. It provides a blocking effect and immobilizes the surface atoms.
