Research Interests

We are employing fullerenes as model systems to probe molecular dynamics and complexation properties with macromolecules of biological significance.  These studies are also being used to develop a universal model for describing molecular dynamics in liquids. 

Our group is currently utilizing quantum dots to develop biosensors for diagnostic purposes.  The diagnostic technique currently being used to test for prostate cancer (CaP) is dependent on detecting prostate-specific antigen (PSA) levels in the serum.  This diagnostic protocol is however limited since frequently it can not differentiate between CaP and benign prostate hyperplasia (BPH).  The recent discovered correlation between the over-expressed protein delta-catenin and the occurrence of prostate cancer (CaP) provides a unique opportunity for developing a specific diagnostic essay based on this correlation.  The scientific question we are addressing in the initial phase of this project is the feasibility of developing a QD-biosensor that is robust, sensitive, and highly selective toward detecting the delta-catenin protein.
