One-Photon Confocal Fluorescence Imaging

New imaging technology may lead to early detection of neurological illnesses such as Alzheimer’s disease, allowing doctors to diagnose and treat patients more swiftly. The super-resolution imaging technique combines position emission tomography (PET) with an external motion-tracking device to provide incredibly detailed brain images. The patient’s undesired movements frequently hamper the quality of brain PET [..]

Graphene Quantum Dots For Optoelectronic Applications

The development of a blood-oxygen sensor (that clips onto your finger) eliminated the need for costly, risky, time-consuming invasive measurements that required drawing of blood and provides accurate results in real-time. Modern optoelectronics technologies have made “medicine” much more accessible, quicker, and safer. However, the blood-oxygen sensor can only measure oxygen saturation in the circulatory [..]

III-V Photodetectors For Silicon Photonics

A highly sensitive optomechanical ultrasound detector integrated onto a silicon photonic chip has been developed by researchers. The device is 100 times more sensitive than state-of-the-art piezoelectric detectors of identical sizes. Their design could substantially improve the performance of ultrasound detectors in a wide variety of biomedical applications. The researchers used a new optomechanical ultrasound [..]

Vein Visualization From Color Images For Medical Applications

Excessive fat accumulation in the liver can lead to serious medical problems, including liver failure. Thus, understanding the distribution of lipids within the liver is a critical step in diagnosing fatty liver diseases. A team of researchers has now shown that near-infrared hyperspectral imaging permits the visualization of lipid content in mouse liver. This technique [..]

Enzyme Study With A Polymer 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 [..]

Vein Visualization From Color Images For Medical Applications

Positron emission tomography (PET Tracer) imaging with 68Ga-pentixafor is an effective diagnostic tool for the central nervous system (CNS) B-cell lymphoma, according to a proof-of-concept study. Targeting the CXCR4 biomarker involved in the growth, survival, and dissemination of aggressive B-cell lymphoma, 68Ga-pentixafor PET imaging shows excellent contrast characteristics between lymphoma lesions and surrounding healthy brain [..]

Vein Visualization From Color Images For Medical Applications

Researchers have demonstrated that X-Ray Holographic Nano-Tomography (XNH) could help accelerate efforts to map neural circuits and ultimately the brain itself. The team describes how XNH can be used to image relatively large volumes of mouse brain and fruit fly nervous tissue at high resolutions. Combined with artificial intelligence-driven image analysis, they reconstructed dense neural [..]

Diagnostic Imaging Automation With Robotic Scanner

While your skeleton helps your body to move, fine skeleton-like filaments within your cells likewise help cellular structures to move. Now, researchers have developed a new imaging method that lets them monitor a small subset of these filaments, called actin. Actin is the most abundant protein in the cell, so when you image it, it’s [..]

Biomechanics – Drug Response In Hypoxia - Spectroscopy

Researchers have demonstrated that a new mapping approach based on near-infrared spectroscopy can distinguish between fat and muscle tissue in the heart. This distinction is critical when using radiofrequency ablation to treat a serious heart rhythm problem known as ventricular tachycardia. Radiofrequency ablation, the only treatment for ventricular tachycardia, involves identifying areas of the heart [..]

Vein Visualization From Color Images For Medical Applications

The tree of life is rich in examples of species that changed from living in water to a land-based existence. Occasionally, some species took the opposite direction. New insights, provided by a CT scan, into the anatomy of the inner ear of prehistoric reptiles, the thalattosuchians, revealed details about one of these evolutionary turning points. [..]

Diagnostic Imaging Automation With Robotic Scanner

Silver Nanocubes can make diagnostic tests that rely on fluorescence easier to read by making them more than 150 times brighter. Combined with an emerging point-of-care diagnostic platform already shown capable of detecting small traces of viruses and other biomarkers, the approach could allow such tests to become much cheaper and more widespread. Plasmonics is [..]

UV Light

The number of COVID-19 cases has not yet hit its peak and supplies of essential personal protective equipment (PPE) such as N95 masks are dwindling, so medical communities are desperately looking for alternative solutions for disinfecting masks that healthcare workers are being forced to reuse. Medical optics solutions can prove very helpful in such conditions.  [..]

Phase Contrast Imaging

Propagation-based phase-contrast CT (PB-CT) is an advanced X-ray imaging technology that can generate higher quality diagnostic breast images than absorption-based CT (AB-CT), at a glandular radiation dose comparable to, or lower than, conventional mammography and digital breast tomosynthesis (DBT). The technology is currently limited to use with synchrotron light sources, but the evolution of compact [..]

QCL

Lasers that switch on and off billions of times per second are the backbone of optical communications networks, but this feat is only possible at certain laser frequencies. A team of researchers has now taken a step towards extending this frequency range by using sound waves to modulate the emission of a terahertz (THz) quantum [..]
