Microrobot Developed for Delivery of Stem Cells to the Brain

Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea have developed a new microrobot that can precisely deliver therapeutic cells to very specific parts of the brain. Their work, recently published in Science Robotics, demonstrates that neural stem cells can be cultured and differentiated on their robot and th (Read more...)

Molecular Motors Drill Through Cancer Cells

A couple of years ago a team of U.S. and U.K. scientists came up with a way of making molecular motors that can drill through cancer cells, destroying them in the process. The researchers, from Rice University, Durham University, and North Carolina State University, used an ultraviolet (UV) light source to energize these motors, but […]

Octopus-Inspired Wearable Biosensor Sticks to Wet and Dry Skin

Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea have developed a new waterproof, wearable biosensor that can stick to the skin in a unique way. Their work, recently published in ACS Applied Materials and Interfaces, demonstrates the biosensor adheres to the skin in wet and dry conditions and can monitor [ (Read more...)

Machine Learning Helps Design Complex Immunotherapies

Researchers from Northwestern University have leveraged machine learning to aid in the design of nanomedicines for immunotherapy. They utilized a high-throughput method to synthesize 800 unique immunostimulatory nanoparticles called Spherical Nucleic Acids (SNAs). “Spherical nucleic acids represent an exciting new class of medicines that are (Read more...)

Crumpled Carbon Nanotube Forests to Power Medical Devices

Most implantable and wearable medical devices benefit from having on-board batteries powering them, but because conventional batteries have specific internal geometries, they end up being blocky and not flexible. This limits development of the electronic devices, especially pliable ones, since the human body itself is mostly soft and flexible. Whil (Read more...)

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...)
