The Dun research group is interested in the development, application, and commercialization of novel nanoprobes that enable nanosurgery of single cells and sub-cellular compartments. Specifically, carbon-based nanoprobes offer significant advantages over existing commercial technologies such as probe durability, minimally damaging to cells, and multifunctional analytic capabilities. In collaboration with several multidisciplinary groups from Temple University, Drexel University, and the University of Pennsylvania, the Dun group utilizes nanoprobes for intracellular delivery and the measurement of cell signals to study cellular functions. NTI-funded research explores using carbon nanopipettes (CNPs) for the real-time detection of intracellular molecules through fluorescent microscopy and surface enhanced Raman spectroscopy (SERS). Long term, the Dun group aims to develop novel tools and techniques to analyze single and multiple cells for use in pharmacology and physiology.

The Promise of Nanotechnology
“The use of nanotechnology in consumer products and industrial applications is growing rapidly, with the products listed in the inventory showing just the tip of the iceberg. How consumers respond to these early products — in food, electronics, health care, clothing and cars — will be a litmus test for broader market acceptance of nanotechnologies in the future.”
