Multiwavelength TIRF Microscopy Enables Insight into Actin Filaments Researchers at the University of California, San Francisco (UCSF) are combining multiple laser excitation wavelengths in total internal reflection fluorescence (TIRF) microscopy to investigate the...
Supercontinuum Sources Enhance UHR-OCT Methods Ultrahigh-resolution optical coherence tomography (UHR-OCT) enables micron-scale, cross-sectional and 3D-imaging capabilities. Supercontinuum sources offer the necessary optical bandwidths, spatial...
Sterilization Effects on Optical Fibers for Clinical Use Optical fibers have a broad range of uses in medical and clinical applications and can be adapted for many invasive and noninvasive procedures. However, any optical fiber to be used inside a human...
EDITORIAL
Photonics – Forever Relevant in Biological Applications Photonic technologies for biological applications — whether they’re currently in development, in trial or already in active use — are advancing at a mind-blowing pace. Given the sheer momentum the biophotonics industry has gained, it’s highly unlikely that this sector will ever obey the laws of inertia. If anything, its velocity is more likely to speed up, both in terms of...

Lasers Transform Drug into More Useful Form Exposure to laser light may make one type of anti-inflammatory drug more effective. Researchers at Osaka University used lasers to induce selective crystallization of the metastable form of indomethacin. The exposed drug remains in that form for up to eight months in air at room temperature. Previous research achieved metastability for less than a day. Active pharmaceutical ingredients that can...
Microlasers Track Cells from the Inside Embedded microlasers could allow scientists to track and distinguish between several hundred thousand cells simultaneously. The approach could enable new forms of cell tracking, intracellular sensing...
Fluorescent Mesh Aids Tissue Regrowth Polymer fibers provide a mesh for tissue growth that can be monitored through near-infrared fluorescence imaging. Originally developed for solar cells, the material, called TQ1, exhibits fluorescent...
Selective Laser Micromelting Creates Medical Implants Selective laser micromelting allows processing of new materials that could be useful in medical implants. Researchers at Laser Zentrum Hannover EV and the University of Rostock used the additive...
Cutting-Edge Multispectral Microscope Aims to Advance Drug Research A new multispectral device is said to have produced the largest microscope image ever, combining 13 color channels gathered by thousands of microlenses into a nearly 17-gigapixel picture. Able to...
Blue LEDs Could Help Preserve Certain Refrigerated Foods Blue light may be the key to keeping chemical preservatives out of certain food products. A team of scientists from the National University of Singapore has found that blue LEDs have strong...
Identification of Ion Channel Mechanics Yields Optogenetic Insights Researchers at the University of California, Santa Cruz, have identified the molecular mechanism involved in the light-induced activation of Channelrhodopsins — a discovery that could help...
Boron Compounds Employed to Create OLEDs Chemists at Goethe University Frankfurt have developed a new class of organic luminescent materials through the targeted introduction of boron atoms into graphene. The compounds exhibit an intense...
Graphene Confines Light for Nanomolecular Sensing A plasmonic sensor made of graphene can conduct complex analyses of the smallest molecules without altering them. The device overcomes a limitation of traditional IR absorption spectroscopy,...
Light-Activated Technique to Improve, Refine Chemotherapy Treatments A new technique that uses light to activate chemotherapy drugs in specific cells shows promise as a way to improve the effectiveness of cancer therapies while preventing severe side effects. By...
Spectrometer Aims at Disease Detection via Breath Analysis An IR frequency comb spectrometer could help clinicians detect diabetes, infections and cancers by analyzing the air patients exhale. The system uses a commercial frequency comb, variable-length...
Microscopy Platform Enables Ultrastable Measurements Stable enough to track the movements of individual molecules over many hours, a new measurement platform for microscopes could enable a deeper understanding of subcellular processes. The technology...
Optical Cavity Allows for Measurement of Nanosystems A new type of microscope uses an optical cavity to dramatically enhance image signals and enable detailed measurements of the structure and movements of individual nanoparticles The technique has...
RAPIDSCAN
Optical Glucose Sensor on the Road to Commercialization A University of Leeds spin-out company is seeking to commercialize an optical glucose sensor that could make finger-prick blood tests unnecessary for people with diabetes. Glucosense Diagnostics Ltd. intends to make tabletop and wearable versions of the device, which is now in clinical trials. The sensor uses a nanoengineered silica chip with an active layer of ions that fluoresce when...
