Sutures and staples are the traditional methods for closing surgical incisions and wounds in emergency situations. However, these methods can be inadequate in complex surgeries and cannot make an air-tight or liquid-tight seal on a lung or artery wound or incision. Now researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have created a surgical glue that is squirted onto wounds and then sets to form an elastic air-tight or liquid-tight seal in just one minute. Successfully tested in animals, the sealant has enormous promise for life-saving use in humans.

NIH researchers have devised a biochemically formulated patch of dissolvable microneedles for the treatment of type 2 diabetes. The biochemical formula of mineralized compounds in the patch responds to blood chemistry to manage glucose automatically. In a proof-of-concept study performed with mice, the researchers showed that the chemicals interact in the bloodstream to regulate blood sugar for days at a time.

A study activated genes in human stem cells that initiate biomineralization, a key step in bone formation, according to a science team. Scientists engineered spider web silk combined with silica to activate cell membrane protein receptor integrin. The research will help scientists model intracellular pathways that govern bone formation and efforts to cure diseases such as osteoporosis and calcific aortic valve disease.

Scientists have invented a major new advance in DNA nanotechnology. Dubbed 'single-stranded origami,' their new strategy uses one long, thin noodle-like strand of DNA, or its chemical cousin RNA, that can self-fold -- without even a single knot -- into the largest, most complex structures to date. The strands forming these structures can be made inside living cells, opening up the potential for nanomedicine. Read more form Arizona State University.
