  • Publication number: 20190256171
    Abstract: Provided is an anchor for a ship that may facilitate retrieval of the anchor as a folding operation of the anchor is smoothly performed by improving a design of a contact portion such that a mechanical contact resistance of components that perform a folding operation of the anchor is minimized. Consequently, the anchor may be easily retrieved without cutting the wire or the iron chain, that is, without loss of the anchor in a situation in which the anchor arm is caught by an underwater structure not to be pulled out when the ship leaves a harbor after the mooring.

  • Publication number: 20190127784
    Abstract: A digital assay for a micro RNA (miRNA) or other target analyte in a sample makes use of nanoparticles that absorb light at the resonant wavelength of a photonic crystal (PC). Such nanoparticles locally quench the resonant reflection of light from the PC when present on the surface of the PC. The nanoparticles are functionalized to specifically bind to the target analyte, and the PC surface is functionalized to specifically bind to the nanoparticles that have bound to the target analyte. The sample is exposed to the functionalized nanoparticles, and the individual nanoparticles bound to the PC surface can be identified and counted based on reduced intensity values in the reflected light from the PC. The number of bound nanoparticles that are counted in this way can be correlated to the abundance of the target analyte in the sample.

  • Publication number: 20190120766
    Abstract: Photonic Resonator Outcoupler Microscopy (PROM) is a novel, label-free approach for dynamic, long-term, quantitative imaging of a sample on a surface of a photonic crystal (PC) biosensor, in which components of the sample outcouple photons from the resonant evanescent field, resulting in highly localized reductions of the reflected light intensity. By mapping changes in the resonant reflected peak intensity from the PC surface, components of a sample (e.g., focal adhesions) can be detected and dynamically tracked. To demonstrate the simplicity and utility of PROM for focal adhesion imaging, PROM images are compared with biosensor images of surface-bound dielectric permittivity and with fluorescence microscopy images of labeled adhesion molecules in dental stem cells. PROM can dynamically quantify the surface-attached cellular mass density and lateral dimensions of focal adhesion clusters.
