Laser Imaging Assesses Sunscreen Safety
WASHINGTON, Dec. 2, 2011 — In an attempt to answer safety questions about the use of nanoparticles in sunscreen, a new laser imaging technique has been developed to assess the risks associated with one of sunscreen’s ingredients — zinc oxide (ZnO). Overlay of the confocal/multiphoton image of the excised human skin. Yellow color represents skin autofluorescence excited by 405 nm; the purple color represents zinc oxide nanoparticle distribution in skin (stratum corneum) excited by 770 nm, with...

Dec 1, 2011 — Mad City Labs Inc. of Madison, Wis., has opened a direct sales office in Zurich. It established Mad City Labs GmbH to enhance service and support to its European customers and to strengthen its relationship with its distribution network and business...
Proper Load Distribution Ensures Stable Operation
Dec 1, 2011 — With vibration-isolated platforms, questions of load distribution and static stability of pneumatic support systems are not always properly understood. This can create difficulties when setting up modern optoelectronic systems. Optical tables on...
Quantum Cascade Lasers Enhance Mid-IR Spectroscopy
Dec 1, 2011 — Voltage-tunable output wavelength, broad gain spectra, high output power and efficiency, and innovative cavity geometries give quantum cascade laser-based sensor systems an edge in applications from gas analysis to chemical sensing. Most vapor...
Research at the Nanoscale Boosts Green Photonics
Dec 1, 2011 — Improving the efficiency of thin-film solar cells is a key challenge, and some believe that nanophotonics could be the answer. Nanophotonic structures give us better control over light, enabling us to manipulate it in ways never seen before...
Smart petri dish analyzes cell growth
PASADENA, Calif. — Built from a smartphone, a commercially available cell phone image sensor and some Lego blocks, ePetri isn’t like other petri dishes. The compact, lens-free microscopy imaging platform can track cell cultures and bacteria as they incubate....
Microscopy Technique Targets Solar Cells
PITTSBURGH, Nov. 30, 2011 — A new take on a microscopy technique could help in the design of more energy-efficient solar cells. Although current plastic solar cells are low in cost and easy to produce, they are not energy-efficient. Researchers at the University of Pittsburgh...
Smarter Way to Make UV Beams
ANN ARBOR, Mich., Nov. 30, 2011 — A better way to build compact ultraviolet (UV) light sources with low power consumption has been discovered using an optimized optical resonator, which could lead to improved information storage, microscopy and chemical analysis. Researchers...
Zeiss Marks CrossBeam’s 10th Anniversary
PEABODY, Mass., Nov. 30, 2011 — Carl Zeiss Microscopy, a Carl Zeiss Group company, recently celebrated the 10th anniversary of its CrossBeam FIB-SEM (focused ion beam-scanning electron microscope) technology. The ceremony was held at the Center for Composite Materials at the...
Blocked Holes Enhance Light Transmission
PRINCETON, N.J., Nov. 28, 2011 — Placing a metal cap over a small hole in a metal film does not stop light from passing through the hole, but rather enhances its transmission — quite contrary to the conventional thought that blocking a hole would allow less light to pass...
Carbon Nanotube Forest Camouflages 3-D Objects
ANN ARBOR, Mich., Nov. 23, 2011 — One of the unique properties of carbon nanotubes — the low refractive index of low-density aligned nanotubes — also has a unique application: making 3-D objects appear as nothing more than a flat, black sheet. Researchers from the...
AFM Measures Mechanical Properties of Living Cells
WEST LAFAYETTE, Ind., Nov. 22, 2011 — A new atomic force microscope (AFM) technique that measures the mechanical properties of living cells could be used to diagnose human disease and better understand biological processes. Researchers from Purdue University and the University of...
Leica Signs Gated STED Development Deal
WETZLAR, Germany, Nov. 16, 2011 — Leica Microsystems signed an agreement with the Max Planck Society and the German Cancer Research Center (DKFZ) to develop gated stimulated emission depletion (STED) microscopy, the next generation of the superresolution technique. Under the...
