General description

Mercaptosuccinic acid(MSA) is a chiral multifunctional intermediate material used as a stabilizing and capping agent in the synthesis of biologically active sulfurs.

Application

MSA has been used to cap cadmium telluride quantum dots(QDs) and nanocrystals for a wide range of applications like detection of benzoic acid and total paraben based preservatives in food items, biological fluorescent labelling in bio-imaging and can bond with antibodies or antigens for biomedical applications. MSA may be coated on gold nanoparticles(AuNPs) as a reducing agent and a surface modifier that finds potential application in fluorescent detection of mercury.
