The Viability of Meta-Optics for High-Quality, Full-Color Imaging

Researchers at Princeton University and the University of Washington have developed a full-color nano-camera the size of a grain of salt. 1.6 million cylindrical nano-posts were etched on a silicon nitride layer. A neural image reconstruction algorithm manipulates the morphology of these nano-posts to create wide field-of-view (FOV) full-color images.

Scientists Edge Closer to Probe that Would Inspect Atherosclerotic Plaques by Forcing Molecules to Sound Their Presence

Skoltech researchers and their colleagues have come one step closer to a working optoacoustic endoscopic probe — a device that could slip inside a blood vessel and analyze atherosclerotic plaques by shining laser light on them to make them wobble like a loudspeaker membrane and betray their chemical composition with an ultrasound signature.

Researchers Design Broad-Range Luminescent Boltzmann Thermometer

Luminescent thermometers become progressively essential for remote, non-invasive temperature sensing at particularly small lateral dimensions, as contact-based detection methods only function in a partial way or even not at all. Standard application areas are temperature recording on catalytic surfaces or in biomedical procedures.
