Yimin Chao obtained his PhD in Nanosciences from Newcastle University in 2004 with a thesis that Electronic and optical properties of nanostructured materials. He held postdoctoral research fellowship at the Wolfson Chemical Nanosciences Centre at Newcastle between 2004 and 2007 on Nanoscale sensors for genomic and proteomic analysis inside the living cell. He joined UEA in 2007.
Yimin Chao’s research interest is in investigating nanostructured systems, from the basic physical and chemical mechanisms of synthesis, through their optical and electronic properties to biological and medical applications. Current research themes include functionalization and characterization of Si quantum dots (Si-QDs); evaporation and deposition of Si-QDs in ultra-high-vacuum (UHV) at relatively low temperatures; biological and medical applications of QDs as luminescence and Raman probes; and applications in floating gate memory devices. His research is carried out both at his laboratories at the University of East Anglia and in central facilities in Europe. These include SRS Daresbury Lab in UK, Max-lab in Sweden and Elettra in Trieste, Italy.
