Chip to Evaluate Health of Immune System from Blood Sample

Knowing how well a patient’s immune system is functioning may be very useful in diagnosing a disease and guiding the course of therapy. Researchers from Nanyang Technological University in Singapore are making this a reality, having developed a hybrid chip that assesses the health of white blood cells in a whole blood sample. The microfluidic (Read more...)

3D Liquid-Cell Electron Microscopy Imaging Now Possible

Electron microscopy revealed a world that exists at scales smaller than the wavelength of light. Advancements in this field have allowed scientists to visualize ever more objects and processes, but actually seeing living cells in 3D and within a liquid environment has been impossible. Now, a team of researchers from Penn State University, Virginia (Read more...)

Microfluidic Device for Rapid Lyme Disease Diagnosis

Researchers at Columbia University have developed a microfluidic device that can diagnose Lyme disease in as little as 15 minutes. The device is particularly accurate in identifying antibody biomarkers that are present during early stage Lyme disease, raising hopes that it could be useful in detecting cases of early infection in a doctor’s of (Read more...)

Low Power MRI Helps Image Lungs, Brings Costs Down

Modern clinical MRIs usually have magnetic field strengths of 1.5 or 3.0 Tesla. These are pretty powerful magnets and it’s the reason that these devices are very expensive. While such strengths have been standard for a long time, the internal hardware and software beyond the magnets have been improving steadily. Now, researchers affiliated wi (Read more...)

New Imaging Technique Reveals Deep Tumors, Helps Attack Them

Tumors deep inside the body can be very difficult to spot, track, and study. The brain, being surrounded by a thick skull, is particularly challenging to image using light, so MRI and CT are currently the go-to imaging modalities when looking at deeply seated tissues. Now, researchers at Stanford University are reporting the development of [&hellip (Read more...)

New Chip for Microwave Imaging of Body

Today’s clinicians are limited to a few imaging modalities, primarily X-ray, CT, MRI, and ultrasound. Microwaves, in principle, can also be used as a useful way to look inside the body. Microwave radiation is non-ionizing, so should be safer than X-rays, but in practice microwave imagers, because of the electronics inside, have remained bulky (Read more...)

Smart Phyjamas for Monitoring Physiological Signals at Night

Researchers from University of Massachusetts at Amherst have developed a new smart pajama, dubbed Phyjama, that can track physiological signals during sleep. Their work demonstrates that the technology can reliably measure heart rate, breathing rate, and sleep position during the course of the night. One day, advances like this can be incorporated (Read more...)

Ultrasound Otoscope to Help Diagnose Middle Ear Infections

Diagnosing infections of the middle ear is prone to a great deal of subjectivity. Antibiotics being the typical treatment option, way too many patients are treated who are actually not infected. This can result in the development of antibiotic-resistant bacteria and a host of other problems. Researchers at the Fraunhofer Institute for Photonic Micr (Read more...)

Nanoscale Light Manipulation for Detection of Tiny Pathogens

Viruses are so small that to be able to detect them using light you need instruments that work on the nanoscale. Sensors so perfect are very hard to make, as most manufacturing processes disrupt nanoscale structures. Now, a team at Purdue University has developed a way to combine 3D plasmonic nanoarrays, special light manipulation devices, [&hellip (Read more...)
