Nanoparticles accelerate and improve healing of burn wounds

InterNano Industry News - August 22, 2015 - 3:45am
Skin thermal burns are a complex and major source of morbidity, mortality and healthcare expenditure. Given the range of causes, from fire associated injury to water scalding, patients often present with multiple and complex burns - wounds that often worsen and expand over the first few days do to the associated underlying inflammation and injury. To facilitate better wound healing, researchers have developed nanoparticles that can both release the potent biomolecule nitric oxide (NO) over time, as well as facilitate nitrosation, the addition of an NO group to a biological molecule, which is central many of NO's activity.

Could stronger, tougher paper replace metal?

InterNano Industry News - August 22, 2015 - 3:45am
Researchers at the Univ. of Maryland (UMD) recently discovered that paper made of cellulose fibers is tougher and stronger the smaller the fibers get. For a long time, engineers have sought a material that is both strong (resistant to non-recoverable deformation) and tough (tolerant of damage). Read more about Could stronger, tougher paper replace metal?Comments
