By 'crumpling' to increase the surface area of graphene-gold nanostructures, researchers have improved the sensitivity of these materials, opening the door to novel opportunities in electronics and optical sensing applications.
With the gadget's unique design as inspiration, researchers now report the development of bottle-brush nanotags that can contain thousands of fluorophores, greatly enhancing the detection and analysis of cells.
Researchers integrated graphene with silicon microelectromechanical systems (MEMS) to make their device. Testing showed it could be used to detect a person's heat signature at room temperature without cryogenic cooling.
The European Commission's DG for Research and Innovation is in the process of gathering data in support of evidence-based policy-making in the field of research and innovation in nanosciences and nanotechnologies.
A new type of 'nanotweezer' capable of positioning tiny objects quickly and accurately and freezing them in place could enable improved nanoscale sensing methods and aid research to manufacture advanced technologies such as quantum computers and ultra-high-resolution displays.
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.
