SANTA CLARA, Calif., Nov. 5, 2012 — Coherent Inc. has acquired Innolight Innovative Laser and Systemtechnik GmbH and Midaz Lasers Ltd., a move it said will provide core technology building blocks for an emerging class of commercial, low-cost, subnanosecond pulsed lasers for...
Fluorescence Microscopy Given New Power
URBANA, Ill., Nov. 5, 2012 — A new method that studies the critical process of cell transport dynamics at multiple spatial and temporal scales has revealed properties of diffusive and directed motion transport in living cells.
DNA Origami Nanolenses to Visualize Single Molecules
BRAUNSCHWEIG, Germany, Nov. 2, 2012 — Overlapping plasmonic fields, created by positioning two gold nanoparticles on DNA origami, form a nanolens that acts as a nanoantenna capable of enhancing the fluorescent emission of a single molecule, researchers in Germany report.
3-D Stress Map Reveals Embryonic Heart Defects
CLEVELAND, Nov. 1, 2012 — Stresses induced in an embryonic heart by blood flow have been visualized for the first time in 3-D using an optical coherence tomography (OCT) method. The technique could provide new insight into how and why heart defects develop.
Semrock Reveals Facility Expansion
ROCHESTER, N.Y., Nov. 1, 2012 — At a ribbon-cutting ceremony last month, Semrock Inc., a unit of Idex Corp.’s Optics & Photonics (IOP) platform, opened a high-volume manufacturing facility capable of producing tens of thousands of optical filters per year.
System measures limits of plasmonic enhancement
DURHAM, N.C., and LONDON – Photonic interactions have been measured for the first time on the scale of a single atom. The ability to quantify the unique properties of light gives physicists a road map to precise control of scattering in metal-based devices such as biosensors...
