Of mice and molecules: In vivo photoacoustic imaging using semiconducting polymer nanoparticles
Delicate oxidation can transform greenhouse gas into useful chemicals
'Trojan horse' gold nanoparticles treatment could beat brain tumors
A "Trojan horse" treatment for an aggressive form of brain cancer, which involves using tiny nanoparticles of gold to kill tumour cells, has been successfully tested by scientists.
Highly efficient nanoparticles could bring down the cost of fuel cells
(Phys.org) —Fuel cells are a promising, non-polluting way to power cars, but their platinum catalysts are so expensive that there's no way current technology could be economically scaled up for widespread ...
Nano-scale gold particles are good candidates for drug delivery
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
'Nanojuice' could improve how doctors examine the gut
Located deep in the human gut, the small intestine is not easy to examine. X-rays, MRIs and ultrasound images provide snapshots but each suffers limitations. Help is on the way.
Clot-building nanoparticles raise survival rate following blast trauma
A type of artificial platelet being developed to help natural blood platelets form clots faster offers promise for saving the lives of soldiers, as well as victims of car crashes and other severe trauma.
Scientists develop a 'nanosubmarine' that delivers complementary molecules inside cells
With the continuing need for very small devices in therapeutic applications, there is a growing demand for the development of nanoparticles that can transport and deliver drugs to target cells in the human ...
DNA-linked nanoparticles form switchable 'thin films' on a liquid surface
Scientists seeking ways to engineer the assembly of tiny particles measuring just billionths of a meter have achieved a new first—the formation of a single layer of nanoparticles on a liquid surface where ...
Researchers create nanoparticle thin films that self-assemble in one minute
The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory ...
Targeting tumors using silver nanoparticles
Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique—and important—properties. Spherical in shape and silver in composition, it is encased in a shell coated with a peptide ...
Opening a wide window on the nano-world of surface catalysis
(Phys.org) —Surface catalysts are notoriously difficult to study mechanistically, but scientists at the University of South Carolina and Rice University have shown how to get real-time reaction information ...
Researchers develop an invisible type of bar code to thwart criminals
(Phys.org) —A team of researchers at Worcester Polytechnic Institute in Massachusetts has developed a type of bar coding system that would be almost impossible for criminals to thwart. As the team describes ...
