People who have lost their eyesight may be able to see thanks to the development of bionic eyes again. According to other studies, these bionic eyes may create streaky images and are too slow to capture quick movements, so they aren’t clear enough for them to depend on to navigate the world. But this novel [..]

The deterioration of photoreceptors is a significant factor in blindness. Patients with localized retinal degeneration may benefit from additional vision function if their blind human retina is made sensitive to near-infrared light. Researchers restored the light sensitivity of damaged photoreceptors using tunable, near-infrared devices. An antibody to temperature-sensitive ion channels was coupled with gold nanorods [..]

Researchers have created a molecular shield that strengthens the usefulness of near-infrared fluorescent dyes and stabilizes them. Because it can effectively penetrate human flesh, near-infrared light is frequently used in fluorescence bioimaging. However, the dyes must also be water soluble and carry functional groups for conjugating with targeting biomolecules, such as antibodies or tumor-binding peptides. [..]

More trustworthy deep learning medical imaging models will be needed as artificial intelligence (AI) is widely used for crucial tasks like diagnosing and treating diseases, necessitating predictions and outcomes about medical care that practitioners and patients can rely on. The objective of a new deep learning method put forth by a group of computer scientists [..]

Magnetic tape and hard disk drives hold much of the world’s archival data. Compared with other memory and storage technologies, optical data storage in tape and disk drives cost less and are more reliable. Archivists may soon have another option—using an extremely fast laser to write data into a 2-millimeter-thick piece of glass, roughly the [..]

Scientists and engineers working in the fields of optical and photonics have been captivated by the rapidly developing, interdisciplinary field of metasurfaces. They view these advanced materials as a path to a new breed of ultra-compact flat optics, such as camera lenses. But most of the metasurfaces that have been demonstrated up to this point [..]

Scientists have created a novel optomechanical integrated device with a resolution of 45 femtometers in a fraction of a second. Importantly, the gadget does not require a tunable laser because of its ultrawide optical bandwidth of 80 nm. The indium phosphide (InP) membrane-on-silicon (IMOS) technology, perfect for including passive components like detectors or lasers, is [..]

High-speed communication channels for supercomputers and data centers could significantly benefit from understanding the physics of lasers at the nanoscale and how they interact with semiconductors, but only if researchers can figure out how and why they work to replicate their findings. The experimental findings of the experts demonstrate that lasers can be made in [..]

By increasing their brightness by more than 150 times, silver nanocubes can make it simpler to read diagnostic tests that depend on fluorescence. The method could enable such tests to become much more affordable and commonplace when combined with an emerging point-of-care diagnostic platform that has already demonstrated its ability to identify minute amounts of [..]

Researchers have created a novel technique for producing color 3D images that operate across the full visible spectral range. Metasurfaces are 2D-engineered materials that are usually made of subwavelength elements. Adjusting the light’s polarization, phase, and amplitude offers excellent control over shaping the optical wavefront. Unlike conventional metasurface-based holography methods, the developed method does not [..]

A brand-new fluorescence microscopy method has been created by researchers to significantly improve the resolution that can be obtained when imaging intracellular structures.
