Leyre Bei Fraile Aguirre

Leyre Bei Fraile Aguirre is a predoctoral student enrolled in the Materials PhD program at the University of Oviedo. She completed her Biotechnology degree (2019/2020–2022/2023) at the University of Oviedo and pursued a master's in Nanoscience and Molecular Nanotechnology (2023–2024) at the Universidad Autónoma of Madrid.
She carried out an internship at the company Táctica Corporativa S.L., working on the detection of toxins using lateral flow immunoassays, where she gained expertise in the synthesis of magnetic nanoparticles, physicochemical characterization techniques, and lateral flow immunoassays.
She has been working for two years in an applied physics laboratory led by Montserrat Rivas Ardisana, the head of the MAGNES research group, focusing on nanomaterials for biological applications. The research group's projects can be found on their website: MAGNES People - NANOBIOAP. Within this group, she completed her undergraduate thesis, titled "Synthesis and Characterization of Nanoparticles for Lateral Flow Immunoassays," and her master's thesis, titled "A Radiofrequency Study of Nanoparticles Deposited on Solid Surfaces for Biosensor Applications." She has also participated as a predoctoral research collaborator in an R&D&I strategic project called NEUMOSENSOR (Ref: PLEC2022-009490), aimed at developing a biosensor for pneumonia diagnosis using magnetic nanoparticle labeling.
She has been awarded two research initiation grants at the IUTA (University Institute of Industrial Technology of Asturias), where she worked on magnetic nanoparticles for rapid SARS-CoV-2 antibody tests (SV-22-GIJON-1-18) and the study of flexible ultra-high-frequency sensors (SV-24-GIJON-1-20).
Additionally, she has presented her research at both national and international conferences, is a co-author of a scientific article titled "Mn-ferrite nanoparticles as promising magnetic tags for radiofrequency inductive detection and quantification in lateral flow assays" (DOI: 10.1039/D4NA00445K), and has served as a member of the local organizing committee for the international conference IEEENANO2024.
She is currently working on her doctoral thesis titled "Design of a Biosensor for the Detection and Quantification of Tumor Vesicles" , co-supervised by Montserrat Rivas from the University of Oviedo and Mónica López Fanarraga, leader of the Nanomedicine Group at the Valdecilla Health Research Institute.
