Anti-reflective coating inspired by fly eyes

The eyes of many insects, including the fruit fly, are covered by a thin, transparent coating made up of tiny protuberances with anti-reflective, anti-adhesive properties. An article published in the journal Nature reveals ...

Great progress for electronic gadgets of the future

Researchers at the Norwegian University of Science and Technology (NTNU) have found a completely new method to check the electronic properties of oxide materials. This opens the door to even tinier components and perhaps ...

Harnessing DNA molecules for disease detection and electronics

DNA molecules express heredity through genetic information. However, in the past few years, scientists have discovered that DNA can conduct electrical currents. This makes it an interesting candidate for roles that nature ...

Energy harvesting goes organic, gets more flexible

Nanogenerators capable of converting mechanical energy into electricity are typically made from metal oxides and lead-based perovskites. But these inorganic materials aren't biocompatible, so the race is on to create natural ...

Single-atom-thin platinum makes a great chemical sensor

Researchers at Chalmers University of Technology, Sweden, together with colleagues from other universities, have discovered the possibility to prepare one-atom thin platinum for use as a chemical sensor. The results were ...

Understanding electron transport in graphene nanoribbons

Graphene is a modern wonder material possessing unique properties of strength, flexibility and conductivity whilst being abundant and remarkably cheap to produce, lending it to a multitude of useful applications—especially ...

A new method to produce gold nanoparticles in cancer cells

Dipanjan Pan, professor of chemical, biochemical, and environmental engineering at UMBC, and collaborators published a seminal study in Nature Communications that demonstrates for the first time a method of biosynthesizing ...
