"Optical Control of Microscopic Systems"
Dr. Samarendra Mohanty

I will introduce recent developments on manipulating several micro/nanoscopic systems optical methods and simultaneous probing of structural/functional changes using multimodal microscopy. The unique multimodal imaging and manipulation platform developed in our lab allows multiphoton excitation, digital holographic imaging, atomic force microscopy, total internal reflection fluorescence excitation, near-field scanning optical microscopy, epifluorescence and phase contrast imaging, integrated with optical tweezers, laser spanner, optical stretcher and laser scissors. I will describe recent introduction of fiber-optic tweezers, scissors, and rotator for manipulation and characterization of microscopic objects at large depths. I will also briefly describe recent use of optical methods for highly-efficient axonal guidance, and gene delivery as well as highly-effective stimulation of neuronal systems with high specificity.
