(Phys.org) — Researchers in Spain have succeeded in building a photodetector that is a billion times more sensitive than other such detectors based on graphene and could herald the use of graphene based light sensors and solar cells. The team, from the Institut de Ciencies Fotoniques, in Barcelona, describe their research and results in a paper they’ve published in the journal Nature Nanotechnology.
(Phys.org) — Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and “personalized medicine” tailored to the specific biochemistry of individual patients.
Kansas State University researchers have come closer to solving an old challenge of producing graphene quantum dots of controlled shape and size at large densities, which could revolutionize electronics and optoelectronics.
(Phys.org) — University at Buffalo researchers are making significant progress on rust-proofing steel using a graphene-based composite that could serve as a nontoxic alternative to coatings that contain hexavalent chromium, a probable carcinogen.

In an article in the highly ranked interdisciplinary journal PNAS, Loïg Kergoat, a researcher at Linköping University, describes how transistors made of plastic can be controlled with great precision.
Synthetic scent hounds: Nanostructured sensor for detection of very low concentrations of explosive
– phys.org
To prevent terrorist attacks at airports, it would be helpful to detect extremely low concentrations of explosives easily and reliably. Despite the development of various sensor technologies, dogs continue to be the most efficient detectors. In the journal Angewandte Chemie, a German and French team has now described a type of micromechanical sensor with a structure derived from the sense organs of butterflies.
Graphene and carbon nanotubes could improve the electronics used in computers and mobile phones, reveals new research from the University of Gothenburg, Sweden.
