Antonio Montoro Bustos (Assoc)

Analytical Chemist

Dr. Antonio R. Montoro Bustos, an analytical chemist, received his undergraduate degree in Chemistry and his international doctorate degree in Analytical Chemistry from The University of Oviedo, Spain. He is presently a Guest Researcher at the National Institute of Standards and Technology (NIST). Dr. Montoro’s current research efforts are focused on the application of single particle ICP-MS (inductively coupled plasma mass spectrometry), for the characterization of nanomaterials at environmentally relevant concentrations, including the validation of the technique against HR-SEM, the evaluation of the role of different coatings on the stability of nanoparticles and the study of the matrix effects on the spICP-MS analytical performances. As an analytical chemist, Antonio has extensive experience in synthesis, solubilization and functionalization of different types of nanoparticles, development of immunoassays, organization of interlaboratory and multidisciplinary projects and in the coupling of different separation techniques such as SEC, AF4, LC to ICP-MS detection for the quantification of a wide range of biomolecules.
