설명

일반 설명

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.[1][2]

애플리케이션

3-MPA is used to produce hydrophilic SAMs, which are terminated with carboxylic acids and can be further functionalized[3] to introduce more complex end groups such as enzymes for biosensor applications.[4] SAMs of 3-MPA are capped on ZnSe quantum dots for the electrochemical detection of dopamine.[2] 3-MPA is used as a capping agent on CdTe quantum dot nanocrystals (QD NCs) for use as labeling materials in biomedical applications.[5][6] 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.[7]
