Peptide Particles Ferry Drugs Across Blood-Brain Barrier

Most drugs, genetic materials, and other therapeutic agents are very difficult to use inside the brain because of the blood-brain barrier. There have been attempts to use ultrasound and microbubbles to create temporary passages through the barrier, including as a possible therapy for Alzheimer’s disease, but this is approach is not easy or id (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...)

Soft Robotic Glove for Hand Grasp Rehab

All sorts of conditions, including muscular dystrophy, ALS, and partial spinal cord injury, result in patients losing their ability to confidently grasp objects with their hands. Regaining this important capability is usually a priority, as it is one of the biggest impediments to living a normal life. Now, researchers at Harvard’s Wyss Instit (Read more...)

Exoskeleton Walks to Brain’s Commands

Powered exoskeletons are used to help people with lower limb paralysis get on their feet and allow post-stroke patients to recover faster. They’re pretty impressive devices, but people who are severely disabled, including those suffering from tetraplegia, can’t get much benefit from them. Now, a team of researchers in France has succeed (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...)

Implantable Nanolasers for Tissue Imaging, Neurotherapy

A variety of imaging techniques and technologies, such as optogenetics, could benefit from devices that can emit visible laser light from inside tissues. Conventional lasers are too large, while nanolasers tend to be inefficient, heating up too much, and typically require damaging ultraviolet light to power them. Now, researchers at Northwestern an (Read more...)

FDA Clears Siemens Artis icono Angiography Systems

Siemens Healthineers won FDA clearance for the ARTIS icono angiography systems that are designed for use in a variety of procedure types. The ARTIS icono 2D/3D biplane system is intended for neuroradiology and abdominal imaging while the ARTIS icono floor has a single fluoroscope and is designed for vascular, interventional cardiology, surgical, an (Read more...)
