María Antonia Herrero (born 1978) is a chemist who works in the faculty of chemical sciences at the University of Castilla–La Mancha (UCLM) in Ciudad Real.

[3] Her work centres on the study of the applications of nanomaterials, specifically nanotubes, that can be modified for distinct uses in such diverse fields as medicine (e.g. as conveyors of drugs to treat illnesses like cancer or Alzheimer's disease).

[1][2] After she joined the nano-chemistry group at UCLM, her research focused on microwave radiation for the activation of carbon nanostructures in solvent-free conditions, developing multifunctional synthetic materials to be used in science and biological applications.

[4] In 2012, María Antonia Herrero obtained a grant from the Iberdrola Foundation to develop a project in the field of energy and the environment.

In 2012, the Iberdrola Foundation granted her an important line of investigation with the main subject of integration of carbon nanomaterials into solar cells.
