Electrospinning Gun Protects Wounds with Nanofiber Mesh

An Israeli company called Nanomedic has begun showing off its impressive device for applying an electrospun material to the surface of wounds. Electrospinning involves using electricity to produce extremely fine polymer threads. This technology is almost always used during manufacturing. The SpinCare product is the first portable electrospinning de (Read more...)

Nanocomposite Heart Valve to Replace Animal-Derived Devices

Researchers at the University of British Columbia (UBC) have developed a nanocomposite biomaterial heart valve that could provide an alternative to the animal valves that are currently used as heart valve replacements. Moreover, the nanocomposite valves can be delivered to the heart through a transcatheter, allowing for minimally invasive placement (Read more...)

Injectable Bone Scaffolding Made of Plant Cellulose

The majority of bone implants, cements, and grafts are hard objects that don’t always work well in filling the space they’re supposed to inhabit. Soft objects can gently expand and relocate their mass evenly over a volume, and they tent to be less dense so as to leave room for cells to make home inside […]

Researchers Give Animals Infrared Vision

Even those of us with perfect vision are actually blind in some ways. Many birds can see ultraviolet light and snakes can detect infrared, something we don’t have the right retinal cells for. But now researchers at University of Massachusetts Medical School and University of Science and Technology of China have shown that it may soo (Read more...)

Microrobots Take Minutes to Detect C. diff in Stool Samples

Detecting bacterial infestations within the GI system, particularly using low cost methods, takes so much time that treatment is often administered too late. Clostridium difficile (C. diff) is a particular nasty nuisance that kills many frail patients, and even with a hospital lab it can take up to two days to get the results. Researchers (Read more...)

Graphene Biosensors to Detect Lung Cancer

Exhaled breath is rich in biomarkers that can point to the presence of disease. In particular, ethanol, acetone, and isopropanol can point to the presence of lung cancer, so having a way of measuring these chemicals in breath might provide a way to diagnose lung cancers or to screen for them. Current methods of measuring […]

Electronic Nanomesh Gently Hugs Beating Heart Cells

Unlike with most other cells, studying the heart’s beating cardiomyocytes is prone to difficulty because attaching rigid sensors to moving cells hinders the movement of those cells. A collaboration of Japanese scientists at University of Tokyo, Tokyo Women’s Medical University, and RIKEN research institute have developed (Read more...)

Spray Gel Helps Prevent Cancer Spread Following Surgery

All too often after tumor resections cancers end up spreading to other parts of the body. Metastasis is not well understood, but researchers at University of California, Los Angeles, University of North Carolina, Chapel Hill, South China University of Technology, Guangzhou and Fudan University in China, have developed and tested a re (Read more...)
