As the world increasingly ramps up to a future of wearable technology, sensors that can measure strain, and thus bodily motions, in real time have become a hot commodity....

Scientists at the National Institute of Standards and Technology (NIST) have developed the first miniature laser in which the light is guided along the floor of an open metallic trench. The laser could act as a nanoscale device to sense...

Researchers have developed a way to build multifunctional nanoscale structures using aluminum nanocrystals. The structures have an aluminum core and are dotted with even smaller metallic islands. The nanocrystals are used as a base for creating size-tunable transition-metal nanoparticle islands...

In 2015, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) developed the first on-chip metamaterial with a refractive index of zero, meaning that the phase of light could be stretched infinitely long. The metamaterial...

Scientists at Osaka University in Japan have shown that non-labeling multiphoton microscopy (NL-MPM) can be used for quantitative imaging of cancer that is safe and requires no resection, fixation, or staining of tissues....

Using DNA from salmon, researchers in South Korea hope to make better biomedical and other photonic devices based on organic thin films. Often used in cancer treatments and health monitoring, thin films have all the capabilities of silicon-based devices with...

Researchers at King’s College London have developed a series of nano-structured materials that rapidly change the polarisation of light faster than electronic methods currently allow. The materials, described in today's Nature Photonics, could lead to faster data transfer rates, better...

University of Michigan researchers have developed a laser-based method that could be used to detect chemicals such as explosives and dangerous gases quickly and accurately.  Eventually, this method could be used in systems placed in airports, for the environmental monitoring...

Syntec Optics develops and manufactures medical optics for emerging biomedical imaging technologies based on nanoparticles, optofluidics, photoacoustics and laser propulsion....

Fluorescence microscopy gives researchers incredible power to illuminate the tiniest structures and capture the real-time activities of live cells by tagging biological molecules with a veritable rainbow of fluorescent dyes....
