Description

General description

3-Mercaptopropionic acid (3-MPA) is used as a self-assembled monolayer (SAM) with a thiol and carboxylic groups. It has short carbon chains and is mainly used as a capping agent on a variety of nanoparticles.

Application

3-MPA is used as a capping agent on CdTe quantum dot nanocrystals (QD NCs) that may be used as labeling materials in biomedical applications. SAMs of 3-MPA are capped on ZnSe quantum dots for the electrochemical detection of dopamine. It can also be used to modify the surface of iron oxide nanoparticles (Fe2O3) in the extraction and preconcentration of Al3+ and Cr3+ ions from different biological samples.

Packaging

5, 100, 500 g in glass bottle
