The toxicity of carbon nanotubes (CNTs) has received significant attention due to their usage in a wide range of commercial applications. While numerous studies exist on their impacts in water and soil ecosystems, there is a lack of information on the exposure to CNTs from the atmosphere.
Scientists have developed a method for preparing methylammonium-lead bromide hybrid nanoparticles with extraordinary luminescence. This work has successfully increased the luminescence efficiency of nanoparticles up to 80% and has also proven their high stability under ultraviolet visible light.
It is evident from samples from mammoths, bears, and other fossils: sequenceable DNA can last up to several hundred thousand years. But one does not necessarily need fossil bones as capsules of silica glass spheres can do the same job.
With properties that promise faster computers, better sensors and much more, graphene has been dubbed the 'miracle material'. But progress in producing it on an industrial scale without compromising its properties has proved elusive. University of Groningen scientists may now have made a breakthrough.
Researchers have designed and developed hybrid gold-silica nanoparticles, which are turning out to be genuine therapeutic 'Swiss Army knives'. Tested in mice and on cultured human cells, they make it possible to combine two forms of tumor treatment and three imaging techniques.
