High Throughput Poration of Mammalian Cells using Femtosecond Laser-activated Plasmonic Substrates, at Tokyo Metropolitan University (Tokyo, Japan), Thursday, January 29, 2015:
    We present a new cell transfection method that uses femtosecond laser-excited localized surface plasmons (LSPs) on a nanostructured micropyramid array. Our gold-layered micropyramids have nano-apertures at the apex to form high local electric field enhancements, or “hot spots.” These hot spots form microbubbles that temporarily perforate mammalian cell (HeLa S3) membranes and allow dye molecules and plasmid vectors to diffuse through the membrane openings. We optimize our laser parameters for successful poration and high cell viability. Our nontoxic, efficient, and scalable technique...

    The interaction of infrared radiation with isolated molecules: intramolecular nonequilibrium, at Lasers ¹86 Conference (Orlando, FL), Saturday, November 1, 1986
    Anti-Stokes signals from various modes of isolated, infrared multiple photon excited molecules are measured to determine the intramolecular distribution of vibrational energy. This paper presents results for CF2HCl, CF2Cl2, SF6 and 1,1-C2H4F2. All but CF2HCl exhibit collisionless changes in Raman spectrum after infrared multiphoton excitation. This shows that the excitation modifies the population of these modes. Even though the symmetric SF6 molecule reaches an intramolecular equilibrium within the 20 ns time resolution of the experiment, the other molecules exhibit a distinct nonequilibrium...

    MilliHertz Surface Spectroscopy, at Ninth International Conference on Laser Spectroscopy (Bretton Woods, NH), Thursday, June 1, 1989
    A technique that has been repeatedly employed in high resolution light scattering experiments is that of light beating, or heterodyne, spectroscopy. By detecting the beating signal between the scattered light and a 'local oscillator' derived from the same laser source, one can obtain ultrahigh spectral resolution, independent of the random fluctuations of the light source. We reported earlier of a novel Fourier transform heterodyne spectroscopy (FTHS) technique with high resolution which is simpler and more direct than the conventional heterodyne technique; we have since improved our...

    Note: This is my first ever computer presentation. It was given using HyperCard on an Apple Macintosh Portable (well, barely portable; it was not for another 6 months that Apple would ship the first PowerBook). The image was projected using an LCD-panel that had to be placed on an overhead projector.
