Abstract:
Nanotechnology offers tremendous potential to meet 21st Century technical challenges in many areas of high global priority. Photonics is the science and technology involving light.Nanophotonics, created at the interface of nanotechnology and photonics, deals with interaction between light and matter on nanometer length scales, which can be utilized to produce novel effects and develop nanoscale devices1. The world faces a major challenge in meeting future energy needs. Nanophotonics provides new approaches for solar energy conversion. In areas of solar energy conversion, we are developing new nanophotonics-based approaches for efficient harvesting of solar photons over the entire solar spectrum from UV to IR, and their efficient conversion to electrical energy (e.g. direct or electrochemical conversion). Nanotechnology also offers new approaches to thermoelectric and energy storage which we are pursuing to integrate them with solar energy harvesting, thus providing a comprehensive energy solution.Biophotonics, created by interfacing photonics with biotechnology, deals with the interaction of light with biological or biologically-relevant matter2. It provides novel means for optically probing cellular and tissue processes. We have developed an integrated Biophotonics Platform that combines a number of nonlinear optical imaging modalities, e.g. CARS ,two-photon excited fluorescence and FLIM, with quantitative Raman spectrometry for real-time bimolecular cell diagnostics. Using this platform, we have studied cell cycle progression in normal and malignant cells and cellular mechanism of apoptosis, as well as stem cell differentiation and reprogramming. Localized, confocal quantitative Raman microspectrometry provides cellular site-specific molecular concentrations and their changes as a function of cellular processes or drug-cell interactions.Another major area of our research is nanobiophotonics and nanomedicine which combines nanotechnology, biotechnology and photonics utilizing multifunctional nanoparticles3. We are developing multifunctional nanoparticles containing multiple imaging and sensing probes for in-vitro rapid detection of diseases (cancer, neurological)and infections (such as swine flu, HIV, HPV, tuberculosis and malaria), together with nanoplatforms for highly effective multimodal imaging and targeted therapy with minimal side effects. We are also developing nanoplexes which involve electrostatic complexetion of genetic materials for non-viral gene/si-RNA delivery for other health care issues e.g. aging, genetic disorder, addiction influenza, HIV, tuberculosis and obesity.Nanotechnology also provides new solutions for environmental monitoring as well as decontamination. Some examples of the impact of nanotechnology on environmental issues will also be discussed.Nanotechnology provides major advances in information technology, surveillance, security encoding, and chem/bio detection For information technology, our program focuses on efficient high bandwidth and high density integration of optical communication using photonic crystal circuitry, high capacity data storage using two-photon 3-D writing and high contrast LED displays. In addition, we are pursuing development of new metamaterials, a novel class of future nanomaterials for information technology and surveillance.
