Active Projects in the Lab

Nanomaterials, are the core of an emerging technological revolution because they offer unique thermal, mechanical, electronic, and biological properties. Combining these properties with their remarkable recognition capabilities has resulted in analytical systems with significantly improved performance and novel applications across physics, chemistry, biology, and engineering. Owing to these characteristics, our group is interested in the development, characterization, and application of novel analytical strategies combining nanomaterials, electrochemistry, and microfluidics; in particular those that could provide significant advantages for biomedical research. A few of the projects currently underway are:

Microchips are one of the most promising analytical platforms due to the great advantages with respect to conventional bench-top equipment. Microfluidic devices are able to offer custom design, high throughput, sensitivity, selectivity and portability. Our group is interestd in the development of capillary electrophoresis based devices as well as paper-based microfluidic devices.

Electrochemistry is the study of redox chemical reactions at the surface an electrode. In our case, it provides a simple, fast, an inexpensive way to perform detection of analytes at low concentrations. Our lab is interested in the developemnt of new electrodes, their chemical modifications, and their applications.

Example of an adsorption curve experiment Interaction of Macromolecules with Nanostructred Materials
The adsorption of proteins to surfaces is a central concern for the rational design and application of materials. The rate and strengths of the initial physical interactions between proteins and surfaces dictate (to a large degree) the final conformation, stability, and activity of such proteins. Our group is specifically interested in understanding the effect of the applied potential on the adsorption process.

Picture of Dr. Torresi and Kaylee Clark in Sao Paulo US-Brazil: International Research Experience for Students
Recent developments in nanotechnology and microfluidics have allowed the understanding and rational utilization of a series of micro total analysis systems (uTAS). Considering this, the IRES program aims to provide students an enriching research experience and link chemical properties with a real-world analytical problem.

A recent study stated that lead is still the most prevalent contaminants in US school drinking water. This is critical because lead can enter drinking water from service lines and lead-containing plumbing, particularly in the presence of corrosive water. Aiming to identify potential sources of lead contamination in drinking water outlets in schools, our lab is now testing water samples from schools in South Carolina.
