Dr. Leo Bey Fen
University of Malaya, Malaysia
Dr. Leo Bey Fen is a senior lecturer at the Faculty of Medicine, University of Malaya (UM). She obtained her PhD from the London Centre for Nanotechnology (LCN), Imperial College London (UK) in 2015. She is the current consultant at the Electron Microscopy Services, Central Unit of Advanced Research Imaging (CENTUARI), UM. She is also an associate research member at Nanotechnology and Catalysis Research Centre (NANOCAT). Her research interest includes synthesis and characterisation of nanomaterials, functionalisation and applications of nanomaterials (e.g. biosensors for pathogen or toxin identification, antimicrobial agents, drug delivery, nanomagnetic gloves) and nanosafety & toxicology assessment of nanomaterials. In these research projects, Synchrotron Small Angle X-Ray Scattering (SAXS) at DIAMOND Light Source, High Resolution Transmission Electron Microscopy (HRTEM), Time of Flight – Secondary Ion Mass Spectroscopy (TOF-SIMS), Focused Ion Beam – Scanning Electron Microscopy (FIB – SEM), RAMAN spectroscopy, confocal microscopy and ICP-MS analysis were used to characterise as-synthesised nanomaterials and investigate the stability of ENMs in biologically relevant environments.
Many of her peer reviewed papers on the topics including: nanomaterials synthesis and characterisation, nanotoxicology, biosensors etc. have been published in high impact journals. Moreover, the first-authored paper ‘The Stability of Silver Nanoparticles in a Model of Pulmonary Surfactant’ that has been published in the ES&T and noted as a science highlight in the UK Diamond Light Source Annual review. Besides, Dr. Leo also serves as manuscript reviewer for scientific papers including New Journal of Chemistry, Scientific Reports (Nature), Aquatic Toxicology, RSC Advances and conference papers etc. Her research group had established collaboration between UM, Imperial College London, Leeds University, top class research groups in National Heart and Lung Institute (NHLI) in the UK; toxicology group from New Jersey, US and Diamond Light Source at Oxfordshire.
