Vertical semiconductor nanowire arrays are a promising material for retinal prostheses, which could help restore the eyesight of people suffering from severe retinal diseases. These nanowires could also be used to fabricate bio-inspired photoreceptors and lightweight, highly efficient photovoltaics. In new work, scientists present theoretical and experimental studies on the microscopic optical behavior of highly dense and randomly distributed nanowire arrays embedded in a transparent polymer.

Molecular switches are the molecular counterparts of electrical switches and play an important role in many processes in nature. Nanotechnologist now produced a photographic film at the atomic level and thus tracked the motion of a molecular building block.
New research on the two-dimensional material graphene has allowed researchers to create smart adaptive clothing which can lower the body temperature of the wearer in hot climates.
Researchers have developed an ultra-thin nanostructure gold film with the potential to revolutionise next-generation bio-sensing chips.
Graphdiyne is as flat and thin as graphene, which is the one-atomic-layer-thin version of graphite, but it has a higher porosity and adjustable electronic properties. Researchers describe its simple bottom-up synthesis from tailor-made precursor molecules.
Scientists are looking for ways to make millions of molecule-sized robots swarm together so they can perform multiple tasks simultaneously.
So-called frequency combs play a major role in laser research today. Scientists now succeeded in producing this special kind of light, using simple circular quantum cascade lasers - a result that seemed to contradict conventional laser theories completely.
As a newly emerging two-dimensional material, the metallenes with ultrathin morphology will enable a superhigh atomic utilization for catalysis, leading to the partial homogenization of such heterogeneous catalysts, presenting great potentials in electrocatalytic CO2 reduction reaction.
In order to reduce the number of animal experiments in research, researchers are now combining test tube experiments with mathematical modelling.
Engineers have designed a thin adhesive film that could upgrade a consumer smartwatch into a powerful health-monitoring system. The system looks for chemical indicators found in sweat to give a real-time snapshot of what's happening inside the body.
