Scientists could image SARS-CoV-2 using a helium ion microscope for the first time. In contrast to more traditional electron microscopy, helium ion microscopy does not require a thin metal coating on the samples. It allows a more detailed examination of interactions between coronaviruses and their host cells. The study demonstrates that the helium ion microscope [..]

A group of scientists is working on an advanced X-ray imaging method that will aid in the detection and diagnosis of breast cancer. The noninvasive technology employs dyes known as contrast agents specifically designed to recognize and bind to breast cancer cells at the molecular level. When imaged with a special, cutting-edge computed tomography (CT) [..]

Laser-induced breakdown spectroscopy (LIBS) is a possible rapid, non-contact method for detecting and quantitatively analyzing various isotopes, including hydrogen critical to various 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 a matter of seconds, the [..]

In many ways, our brain and digestive tract are inextricably linked. Recent research has even suggested that bacteria in our gut may have an impact on some neurological diseases. Modeling these complex interactions in animals like mice is difficult because their physiology differs greatly from that of humans. Researchers have created an “organs-on-a-chip” system that [..]

Polarization, or the direction in which light vibrates, is imperceptible to the human eye but contains a wealth of information about the objects with which it interacts. Controlling and characterizing polarization is critical for various applications ranging from biomedical imaging to optical communications. Researchers have created metasurface optics, which allow them to remotely control the [..]

A patent application for an under-display optical fingerprint biometric sensor based on a narrow field-of-view collimator filed has been published by the U.S. Patent and Trademark Office (USPTO). While an in-display version of Touch ID biometrics has not been announced, numerous intellectual property filings and other indications have suggested it is at least under consideration. [..]

Researchers discovered that trap states govern the performance of organic photodetectors, limiting their detectability. Organic photodetectors (OPDs) have enormous potential for low-cost imaging, health monitoring, and near-infrared sensing applications. However, before these applications can be commercialized, the performance of these devices must be improved. Recent research on organic photodetectors based on donor-acceptor systems has yielded [..]

One of the most common types of oral cancer is oral squamous cell carcinoma (OSCC), for which the five-year survival rate has stubbornly remained at 50% for many years, partly due to late-stage diagnosis. Better identifying both OSCC and the non-malignant lesions that can precede it would help to reduce the disease’s impact, and optical [..]

Researchers have developed the next generation of ultrafast data transmission, which could enable already high-performance computing to be provided “on demand.” The technology uses a hybrid silicon-vanadium dioxide waveguide that can turn light on and off in less than one trillionth of a second to unjam bottlenecks in data streams. The researchers show that data [..]

According to a review, collaboration between artificial intelligence systems and clinicians may lead to mutual advancements in glaucoma research and clinical practice. Given that glaucomatous changes to the optic nerve head tissues are an irreversible, timely, and dependable structural and functional evaluation of the eye could aid in glaucoma diagnosis.
