Unique surface structures play a vital role in metamaterials, and scientists have begun looking to nature itself for patterned surfaces from which to draw inspiration. Using a lotus leaf as a template, the new substance is capable of almost total absorption of light across the entire visible spectrum.
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.
