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.
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.
Engineers have designed magnetic protein nanoparticles that can be used to track cells or to monitor interactions within cells. The particles are an enhanced version of a naturally occurring, weakly magnetic protein called ferritin.
Scientists have developed a working laboratory demonstrator of a lithium-oxygen battery which has very high energy density, is more than 90% efficient, and, to date, can be recharged more than 2000 times, showing how several of the problems holding back the development of these devices could be solved.
Scientists announced an important advance in the field of cancer imaging and phototherapy, using a single-agent system that may ultimately change the efficacy of cancer surgery and treatment around the world.
Researchers have successfully constructed a fluorescent biosensor for serum albumin by carefully connecting the two color variants of a green fluorescent protein to the antigen binding fragment of an antibody.
