Dr. Ioana Andreea Brezestean is a Scientific Researcher III (R2 rank) at the National Institute for Research and Development in Isotopic and Molecular Technologies (Cluj-Napoca, Romania). She holds a PhD in Physics (2022) and Master's degrees in Medical Physics (2013, 2015) from Babeș-Bolyai University . Her work focuses on nanomaterial synthesis , SERS substrate development , and environmental/health monitoring through advanced spectroscopic techniques. Current projects include NanedisSERS (bioinspired 3D nanoplatforms for neurodegenerative disease diagnostics) and AL-DIBI SERS (Alzheimer's biomarker detection using gold nanourchins). Her expertise spans nanoparticle fabrication (silver/gold), microfluidic sensor design , and multi-modal characterization (Raman, FT-Raman, SERS, TERS, microscopy). She contributes to eco-friendly nanocomposite development in projects like ECONANO4AUTO (bio-PA materials with chicken feather derivatives). Key collaborations include SINTEF AS (Norway), University of Medicine and Pharmacy 'Iuliu Hațieganu' , and NANOM MEMS SRL . Her methodology integrates DFT calculations , quantum chemistry modeling , and statistical pattern recognition for pathogen resistance analysis.
