Major breakthroughs needed to meet 21st Century technical challenges across areas of top global priority, including alternative energy, healthcare, environmental monitoring, information technology, and world security, will be achieved through a convergence of science. This talk will provide examples of how our institute is conducting multidisciplinary research linking materials Science and engineering with nanotechnology and photonics to create new generation multifunctional hybrid materials for applications in the fields of optical information processing, sensor technology, energy, and healthcare. This talk will focus only on applications to energy and health care


We are developing new photoresponsive inorganic: Organic hybrid materials  for efficient harvesting of solar photons  over a broad spectral range A major direction is development of   photon transforming nanostructures, the  optical nanotransformers  which convert a single ultraviolet photons to two visible photons  and those which upconvert  two or more infrared photons to visible photons to enhance ultraviolet photon utilization, while also harvesting IR photons that are unutilized in conventional solar cells . Our work on perovskites will also be presented.


Nanomedicine provides a new pathway to produce breakthrough approaches for meeting our current and future healthcare challenges such as cancer, neurological disorders, infectious diseases.1-3 Our research applies biophotonics to nanomedicine, using multifunction nanomaterial for bioimaging, sensing, and light-guided and light-activated therapy. A major direction pursued in our lab is brain research with the emerging field of neurophotonics, where we apply these photoresponsive materials for functional mapping of the brain using optical and photoacoustic imaging as well as for noninvasive optogenetic stimulation of brain activity using near-IR absorbing optical nanotransformers.


This talk will conclude with a discussion of future outlook and new opportunities in these fields.
