Skin Biopsies – Millimeter-Wave Imaging

Outliers of a population, e.g., cells with a rare function that arise in fewer than one in a million individuals, are of great interest to biologists. The inherent balance with microscopes between viewing cells at a sufficient spatial resolution while still keeping a large field of view to capture unique specimens has impeded these investigations. [..]

Solar Materials For Ultrathin, Lightweight Solar Panel

High-performance mirrors are critical for the construction of optical resonators in various applications in optics and photonics. Stable resonators narrow the linewidth of continuous-wave lasers, creating optical references for frequency comb stabilization and precision molecular spectroscopy. High-performance, low-loss mirrors at mid-infrared wavelengths can help researchers probe new phenomena with increased precision in chemical sensing, discrete [..]

Dental Exam – NIR Light Outperforms X-Rays

The estimation of dental age remains part of active research in forensic science. For accurate age estimation of living individuals in legal proceedings, a series of clinical and radiological examinations are carried out. The age estimation procedure often includes a physical examination, dental examination with dental status and an X-ray of the dentition, and an [..]

Vibrational Spectroscopy Measures Terahertz, Raman

One of the most widely used techniques to generate light through an efficient electron transfer is called electrochemiluminescence, or electrogenerated chemiluminescence (ECL). ECL mechanisms can be explored via ‘spooling spectroscopy’ in which individual ECL spectra showing emitted light are collected continuously during a potentiodynamic course. The obtained spectra are spooled together and plotted along the [..]

Mitochondria Function As Microlenses

A partnership between artificial intelligence systems and clinicians may lead to mutual advancements in glaucoma research and clinical practice, according to a review published in the British Journal of Ophthalmology. Given that glaucomatous changes to the optic nerve head tissues are irreversible, timely, and reliable structural and functional evaluation of the eye could help in [..]

Thin Film Solar Cells - Efficient, Non-Toxic, Flexible

Moth eye has inspired researchers to design a new, highly effective anti-reflective coating that could be useful for solar panels, smartphones, and tablet computers. These mainly nocturnal creatures have evolved eyes that are non-reflective to protect them from the notice of predators. The non-reflective nature of the moth eye arises because of the periodic nanoscale [..]

Mitochondria Function As Microlenses

Rochester researchers demonstrate a way to track the interactions of microscopic immune cells in a living eye without dyes or damage, a first for imaging science. Combining infrared videography (adaptive optics) and artificial intelligence, the new technique could be a ‘game-changer’ for some clinical diagnoses as well as for fields like pharmaceuticals. The researchers integrated [..]

Thin Film Solar Cells - Efficient, Non-Toxic, Flexible

Researchers employed Nafion as a solid medium for the fabrication of transparent luminescent materials with tunable emissions. These membranes are quite famous for their ability to conduct protons and exchange cations. Nafion is composed of hydrophobic main chains and pendant hydrophilic side chains. The side chains are especially important. When Nafion is introduced to a [..]

Photoplethysmography – Remote Heart Rate Monitoring

A groundbreaking artificial intelligence-powered facial recognition system that can identify people wearing masks has been deployed by law enforcement and intelligence agencies around the globe. The technology can also recognize individuals in extreme low-light conditions. Using a reference image or video as a starting point, the biometric system can ID people with as little as [..]

Thin Film Solar Cells - Efficient, Non-Toxic, Flexible

Apple’s new patent relates to further strengthening both the cover glass display and structural housing glass of future iPhones and other devices like a possible future all-glass iMac. Apple notes that while it may be desirable to coat glass structures with anti-scratch and anti-reflection coatings, they create stress concentrations that make the glass structure susceptible [..]

Mitochondria Function As Microlenses

The ability to monitor progression of retinal vascular diseases like diabetic retinopathy in small animal models is often complicated by their failure to develop the end-stage complications which characterize the human phenotypes in disease. Interestingly, as micro-vascular dysfunction typically precedes the onset of retinal vascular and even some neurodegenerative diseases, the ability to visualize and [..]

Linear Polarization Holography Broadens Applications

The three-dimensional (3D) vectorial nature of electromagnetic waves of light has not only played a fundamental role in science but also driven disruptive applications in optical display, microscopy, and manipulation. However, conventional optical holography can address only the amplitude and phase information of an optical beam, leaving the 3D vectorial feature of light completely inaccessible. [..]

Spectral Filters – IR Region – Remote Thermal Imaging

Will automated infection tracking become standard procedure in airports around the world? Real-time thermal monitoring combined with biometric data that could be immediately extracted and analyzed (using computer vision technology) would help airport personnel quickly identify individuals with potential illness in even the most crowded terminals. Possible points of contact with the individual could also [..]

Optical Transistors

Leading research groups in the field of nanophotonics are working toward developing optical transistors – key components for future optical computers. These photonic devices will process information with photons instead of electrons, thus reducing the heat and increasing the operation speed. However, photons do not interact with each other well, which creates a big problem [..]
