Drug Delivery & Dispensing

A team of scientists at the University of Cincinnati, OH, says that an electrical stimulus can promote the growth of blood vessels and help to speed healing in diabetic ulcers and other hard-to-heal chronic wounds. Their research examines the best stimulus parameters, such as frequency and magnitude,...

A new technique to purify blood uses a nanofiber mesh, which could be useful as a cheap, wearable alternative to kidney dialysis, say a team of researchers at the International Center for Materials Nanoarchitectonics, National Institute for Materials Science in Ibaraki, Japan. The mesh could be incorporated...

William “Bill” Cook started Cook Medical out of a spare bedroom in his Bloomington, IN, apartment in 1963. It was where he and his wife, Gayle, made guide wires, guiding catheters, and other small devices used in diagnostic radiology.

Silk and diamonds are the ingredients for a new kind of tiny glowing particle that could provide researchers with a novel technique for biological imaging and drug delivery. The particles, just tens of nanometers across, are made of nanodiamonds covered in silk.

Researchers at the University of Delaware, Newark, have developed a “smart” hydrogel that can deliver medicine on demand, in response to mechanical force. What’s new about their material, is its ability to release medicine in response to force, a major challenge for people with osteoarthritis, which...

Administering health care in space demands innovative biomedical solutions. Small companies developing products that can be modified for use in space may be eligible for a unique funding opportunity offered through the National Space Biomedical Research Institute (NSBRI).

Researchers at the Institute of Bioengineering and Nanotechnology (IBN) at the Agency for Science, Technology and Research (A*STAR), Singapore, and California's IBM Research - Almaden (IBM) have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely...

Microbeam radiation therapy (MRT) provides tremendous promise for cancer patients due to its ability to destroy tumor cells while protecting surrounding healthy tissue. Yet its clinical use has been limited by the size of the massive electron accelerators called synchrotrons needed to generate the...

Multiple sclerosis (MS) involves an immune system attack against the central nervous system and causes progressive paralysis by destroying nerve cells and the spinal cord. It interrupts vision, balance, and even thinking. Although there is still no cure, there are some medications and alternative treatments that may...
