Development of novel bio-analytical techniques and to investigate protein-protein interaction.

The research work in Zhong’s group has two main focuses. One is the development of novel bio-analytical techniques with unique specificity and sensitivity for high-throughput detection of biomolecules; the other is to investigate host-pathogen interaction using proteomic approaches, both relying on various techniques like chromatography, mass spectrometry, microscopy imaging, and flow cytometry.

Develop sensitive immunoassays for biomolecule detection: Biomolecules in interest usually exist at very low levels in biological samples, and sensitive and high-throughput biosening assays are highly demanded in the field of biomedical research. Our effort will be centered on three aspects for the developments of such tools. One is to enhance sensitivity by adopting DNA amplification techniques in immunoassays. Another is to explore new detection platform of immunoassays by making use of the separation techniques such as capillary electrophoresis and field flow fractionation. The last is to combine nanotechnology to enhance sensitivity and feasibility of the assay.

Study host-pathogen interaction: Identification of the molecular mechanism underlying the pathogenic infection processes helps to assess virulence of pathogens and define pathogenic infectivity for the purpose of epidemic or pandemic control. Such study can also assist the development of new drugs or treatments by better understanding disease progression. Our group devotes our effort to isolating and analyzing protein complexes that are involved in the infection process for better understanding of their functions and the underlying infection mechanisms.
