(nominal inner diameter: 0.6 mm) needles into rotating 40 wt.-% PEI (branched; average molecular weight, M w ~ 25 000; water-free; Aldrich) solutions in methanol. The SWNT/PEI composite fibers were characterized by SEM (LEO 1590 VP microscope) and micro-Raman spectroscopy (Jobin± Yvon Horiba high-resolution LabRam micro-Raman spectrometer; helium±neon(More)
PURPOSE The feasibility of Raman spectroscopy for the noninvasive assessment of axial corneal hydration was investigated. METHODS A scanning confocal Raman spectroscopy system, with an axial resolution of 50 microns, was used to assess noninvasively the water (OH-bond) to protein (CH-bond) ratio as a measure of the hydration in collagen-based phantom(More)
Tissue surface temperature distribution on the treatment site can serve as an indicator for the effectiveness of a photothermal therapy. In this study, both infrared thermography and theoretical simulation were used to determine the surface temperature distribution during laser irradiation of both gel phantom and animal tumors. Selective photothermal(More)
the very beginning of my study not only in solving academic problems as a professor but also as a guardian. I am thankful to my wife Urmila S. Gnyawali for her incredible heartfelt support. My sons Bipul and Ankit are a part of my recreation after jaded day-long work. I would like to thank my research group especially Dr. Yichao Chen at University of(More)
Puroose: To develop an instrument with high spatial resolution probing chemical composition of comeal tissue in live animal model without interference of signals originating from adjacent tissues. Methods: A Raman probe for in viva studies was developed that has the required resolving power in space, obtained by a confocally placed fiber for transportation(More)
