Fano Resonance Optical Coating

A multi-institutional team has developed an optical coating capable of simultaneously reflecting and transmitting the same wavelength. The new class of optical coatings has been dubbed Fano Resonance Optical Coatings (FROCs). Previously, optical coatings were limited to reflecting certain wavelengths of light, or, conversely, to better transmit certain wavelengths through them. With the new technology, [..]

Chest CT Scan - Algorithm Predicts Heart Attack Risk

Coronary artery calcification is an important and independent predictor of adverse cardiovascular events such as heart attacks. But despite this knowledge, and the fact that it can be assessed from any chest CT scan, quantification of coronary artery calcium (CAC) is not automatically integrated into the patient pathway as it requires radiological expertise, time, and [..]

VR Head-Mounted Display - Adaptable Facial Interface

A patent application from Apple relates to their future VR head-mounted display and more specifically to a system that will provide users with the ability to customize the headset’s fit on their face so that it’s comfortable and snug. A head-mounted display is worn on the head of the user and engages the face thereof. [..]

Ink Jet Approach To Print Microdisk Lasers

Researchers have developed a unique ink jet printing method for fabricating tiny biocompatible polymer microdisk lasers for biosensing applications. The approach enables the production of both the laser and sensor in a room temperature, open-air environment, potentially enabling new uses of biosensing technologies for health monitoring and disease diagnostics. The ability to use an inexpensive [..]

SARS-CoV-2 Imaging With A Helium Ion Microscope

Scientists have succeeded for the first time in the SARS-CoV-2 imaging with a helium ion microscope. In contrast to the more conventional electron microscopy, the samples do not need a thin metal coating in helium ion microscopy. This allows interactions between the coronaviruses and their host cell to be observed particularly clearly. The study shows [..]

X-Ray Imaging with CT

A team of researchers is developing an advanced X-ray imaging method that aims to improve the detection and diagnosis of breast cancer. The noninvasive technology uses dyes, called contrast agents, that are specifically designed to recognize molecularly breast cancer cells and bind to them. The dyes will amplify the X-ray signal for tumors when imaged [..]

Laser-Induced Breakdown Spectroscopy

Laser-induced breakdown spectroscopy (LIBS), is a possible rapid, non-contact method for the detection and quantitative analysis of various isotopes including hydrogen critical to a wide range of disciplines (e.g. nuclear energy, hydrogen storage). With no sample preparation requirement, a relatively simple experimental set-up, and the ability to detect all elements in the periodic table in [..]

Organs-On-A-Chip

In many ways, our brain and our digestive tract are deeply connected. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases. Modeling these complex interactions in animals such as mice is difficult to do, because their physiology is very different from humans’. To help researchers better understand [..]

Metasurface Optics

Polarization, the direction in which light vibrates, is invisible to the human eye but provides a great deal of information about the objects with which it interacts.  Being able to control and characterize the polarization is important for a range of applications, from biomedical imaging to optical communications. Researchers have developed metasurface optics that can [..]

Under-Display Optical Fingerprint Sensor

The filing for an under-display optical fingerprint sensor with NFV collimator and TFT/organic imager depicts a biometric sensor implemented in a touch-display layer and covered by a transparent layer. The invention includes a collimator layer and a pixelated image sensor. A collimator is a device that narrows or focuses a beam of particles or light. [..]

Organic Photodetectors

Physicists discovered that trap states rule the performance of organic photodetectors, ultimately limiting their detectivity. Organic photodetectors (OPDs) have a huge potential for applications in low-cost imaging, health monitoring, and near-infrared sensing. Yet, before industrially realizing these applications, the performance of these devices still needs to be improved. Recent research on organic photodetectors based on [..]

Oral Cancer Diagnosis

One of the most prevalent forms of oral cancer is oral squamous cell carcinoma (OSCC), for which the five-year survival rate has stubbornly remained at 50 percent for many years partly because diagnosis is usually made at a late stage. Better identification of both OSCC and the non-malignant lesions that can precede it would help [..]

Data Transmission with Optical Computing

Researchers have developed the next generation of ultrafast data transmission that may make it possible to make already high-performance computing “on demand.” The technology unjams bottlenecks in data streams using a hybrid silicon-vanadium dioxide waveguide that can turn light on and off in less than one trillionth of a second. The researchers demonstrate that it [..]

Glaucoma Research

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 [..]
