RESEARCH INTERESTS

 


           Our group is composed of graduate students, postdoctoral researchers and visiting scholars. Our research interests lie in the area of Bioanalytical Chemistry, Materials and Environmental Chemistry. In Bioanalytical Chemistry, we are working at the interface between Analytical Chemistry and Molecular Bioelectronics. More specifically, our group employs antibodies, cells, nucleic acids, carbohydrates and enzymes to design new assays and biosensors based on electrochemical, piezoelectric and optical techniques that find application in the biomedical and environmental fields. Additional research involves a series of engineered nanomaterials and natural phenolic estrogens for their ability to affect the viability and proliferation of mammalian cells. To assess and distinguish the cytotoxic effect of individual estrogens we are using both MTT tetrazolium spectrophotometric method and Fluorescence assay, while the induction of the cell-specific apoptotic process is being examined by fluorescence microscopy after treatment of cells with fluorescent dyes.

Our Group has extensive expertise in interfacial reaction at metal-metal surfaces using electroless plating. We have specifically studied the mechanism of electroless gold, nickel and cobalt. We employ a combination of surface, structural and morphological techniques to monitor the interfacial reactivity and plating rates, including electrochemical quartz crystal microbalance (EQCM), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and X-ray photoelectron (XPS) analysis. We have also developed EQCM based mass sensor arrays for correlating the bath chemistry with the overall plating quality on industrial wirebond samples.

More recently, our group has also focused on the design and fabrication of U-PAC devices involving a biosensor and a completely automated sampling system requiring minimal user interaction.  The current prototype does not require a laptop (although optional) for signal processing and is completely battery powered.  The user must only insert the sample, turn the pump switch on or off and record the data.  The rigid alignment of the sensor components and the integrated closed fluidics system provide a durable setup for field use and can easily be adapted to remote sensing applications. These advanced sensing systems are aimed to provide individually addressable multi sensing elements, to meet the needs of each patient and/or user.
