Application

meso-2,3-Dimercaptosuccinic acid (DMSA) has been used to form a monolayer on Mg/Ti/Au micromotors to enhance the chelation of toxic heavy metal contaminants (Zn(II), Cd(II) and Pb(II)) from polluted aqueous solutions.
It can be used:
  • As a reducing and stabilizing agent to synthesize monolayer-protected gold clusters.
  • For terminal carboxylation of the oleylamine coated Fe3O4 nanoparticles, to develop targeted curcumin drug delivery system.
