Researchers show how new hydrogel can facilitate microsurgery

Skillful surgeons can do amazing things in extremely small places, but finding better ways to suture tiny blood vessels has been an ongoing challenge for even the best. In new work, researchers show how a new peptide-based hydrogel could one day make that reconnection process easier to perform and less likely to fail.

Carbon nanotube catalysts for converting CO2 to CO

Converting solar or wind into carbon-based fossil fuels might seem anything but green, but when you start with carbon dioxide - which can be dragged out of the air - it's as green as it gets. The technology that makes it economically feasible isn't available yet, but a recently published paper presents nice step forward in the effort to not just sequester CO2, but turn it into a useful fuel that is part of a carbon-neutral future.

Sugar-coated nanoworms for better cancer detection

Nanoparticles could aid diagnosis and treatment of diseases including cancer... if the immune system would leave them alone. A new study shows that inducing crosslinks on nanoparticle surface sugars lets them escape mouse immune system and identifies remaining culprit for human immune recognition of nanoparticles.

Researchers build nanoscale autonomous walking machine from DNA

Researchers have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer detector that could roam the human body searching for cancerous cells and tagging them for medical imaging or drug targeting.

Preventing dental implant infections with silver nanoparticles

One million dental implants are inserted every year in Germany, and often they need to be replaced due to issues such as tissue infections caused by bacteria. In the future, these infections will be prevented thanks to a new plasma implant coating that kills pathogens using silver ions.
