I will focus on fundamental light-matter interactions: manipulate light to induce new chemical and physical phenomena, and leverage these to pursue interdisciplinary projects linking physics, chemistry, materials science and biomedical engineering. The research builds upon my skillset and training, and involves instrumentation, technology, and materials development to extend the capabilities of nanoscale optical processes. I seek to formulate and interrogate new plasmonic/optical cavity enabled near-field phenomena for fundamental studies of liquid-phase surface chemistry, with the aid of applications in regenerative medicine. This will be achieved via the following interrelated projects:
Coherent Control of Surface Chemistry
Quantum coherent control of surface-bound molecules will introduce new chemical mechanisms at surfaces. I will use weak and moderately intense laser field, with the aid of plasmon-enhanced near-field effects, to manipulate the molecular alignments and torsional angles in the liquid-phase. Systems of interest will focus on isolated single-molecules and self-assembled monolayers including biomimetic surfaces. Degree of control will be monitored by laser-coupled, non-contact atomic force microscopy and plasmon-enhanced near-field linear and nonlinear optical spectroscopy with single-molecule resolution. The goal is to maintain and generate energy states that are inaccessible using conventional methods.
Several fundamental advances are anticipated including establishment of a powerful platform for manipulating photochemistry and transformation of our ability to control and to reprogram chemical reaction pathways. Technologically, these fundamental developments will impact efforts to introduce precise controls in biomedical applications such as strategies for optical intracellular delivery and cell manipulations.
Non-Contact Plasmon-Induced Intracellular Delivery
The goal is to develop plasmon-induced intracellular delivery and imaging platforms capable of facilitating efficient and precise delivery of a variety of cargos into living cells, while maximizing their survivability. This NIH funded R00 project has three specific aims which target improved delivery efficiency, throughput, and cell viability in intracellular delivery with an emphasis on stem cell gene editing.
A universal pathway will be created for non-contact intercellular delivery of nanomaterials with varied physical properties and biochemical functionalities. This will provide fundamental underpinnings for development of new minimally-invasive diagnostic methods, single-cell research, and genome therapies. The strength of this research is its broad interdisciplinary insight and scope. This presents unique capabilities that can drive innovation in fundamental science and translational medicine.
