研究领域

Nanomaterials and nanotechnology Our research focuses on synthesis and characterization of nanomaterials with multifunctions for biological and environmental applications. Specifically, we will develop new wet chemical methods to synthesize nanomaterials with well-controlled size, shape and composition. We will employ analytical tools in both chemistry and materials science to characterize these nanomaterials. They include UV-vis-NIR, IR, Raman, NMR, Mass spectrometry, as well as powder X-ray diffraction, SEM, TEM, XPS, AFM, and so forth. These nanomaterials are expected to find use in a variety of applications, such as catalysis, fuel cells, disease diagnosis and treatment. We will further study, for example, the effects of different parameters (e.g. size, shape, composition and surface layer) on catalytic and electrocalytic activities of these materials. For biomedical applications, we will emphasize on drug delivery using these nanomaterials through exploration of their bioconjugation, stability, as well as cellular interactions.
