Professor Marisol Espinoza Castañeda was born in Mexico City in 1982. She obtained her degree in Chemical Engineering at the Universidad Autónoma Metropolitana (UAM) Azcapotzalco Campus, with the project entitled: "Electrochemical study of adrenaline and ascorbic acid with an anionic surfactant and analytical determination in real samples", with which she won the Diploma for research for having obtained first place in the contest for the best thesis, convened by the Division of Basic Sciences and Engineering, awarded by the Azcapotzalco Campus.

She obtained her master's degree in Nanotechnology presenting the project entitled "Prussian blue nanoparticles for biosensing applications" obtained at the Universidad Autónoma de Barcelona, Spain, also her doctorate in Biotechnology was obtained at the Universidad Autónoma de Barcelona, Spain, for the work presented to obtain the doctorate degree with the title: "Study and development of new biosensors based on nanoparticles and nanochannels", for which she obtained the mention of Cum Laude.

She is currently an associate Professor in the Department of Basic Sciences at the Universidad Autónoma Metropolitana, Azcapotzalco Campus. She received support for the incorporation of new full-time professors (2015-2016), granted by the Subsecretaría de Educación Superior (PRODEP), for the realization of the project entitled: "Synthesis of magnetic nanoparticles for future functionalization and application in environmental biosensors for the detection of E. coli in water".

To date, she has directed nine undergraduate theses in Chemical, Physical and Environmental Engineering (4 in process), as well as two Master's theses in Environmental Science and Engineering (one in process). He has published around 15 articles, in scopus he has an H Factor of six and his appointment in the National System of Researchers is Level I.

Her research focuses on the fields of Microbiology, Biotechnology, Bionanotechnology, and Electrochemistry. She has developed work on the synthesis of nanomaterials for use in electrochemical and optical biosensors, and has also worked on the development of rapid electrochemical detection systems for pathogens, as well as on the implementation of bioremediation processes for water and soil.
