Color hologram uses plasmonic nanoparticles to store large amounts of information
Of mice and molecules: In vivo photoacoustic imaging using semiconducting polymer nanoparticles
New nanodevice defeats drug resistance
Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking ...
New nanogel for drug delivery
Scientists are interested in using gels to deliver drugs because they can be molded into specific shapes and designed to release their payload over a specified time period. However, current versions aren't ...
Researchers find easy way to deposit metal nanoparticles on a surface using tape
Nano-antioxidants prove their potential
Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism.
Scientists model molecular movement within narrow channels of mesoporous nanoparticles
Scientists at the U.S. Department of Energy's Ames Laboratory have developed deeper understanding of the ideal design for mesoporous nanoparticles used in catalytic reactions, such as hydrocarbon conversion ...
Unexpected finding shows nanoparticles keep their internal crystal structure while flexing like droplets
A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal ...
DNA nano-foundries cast custom-shaped 3-D metal nanoparticles
Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have unveiled a new method to form tiny 3D metal nanoparticles in prescribed shapes and dimensions using DNA, ...
Nanoparticles get a magnetic handle
A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, and that could be precisely manipulated into position within living cells, has been achieved ...

Gold's unexpected oxidation activity: Decoding the role of water in gold nanocatalysis
Researchers from the University of Houston and Trinity University have for the first time provided direct evidence of a water-mediated reaction mechanism for the catalytic oxidation of carbon monoxide.
Engineers develop new sensor to detect tiny individual nanoparticles
Nanoparticles, engineered materials about a billionth of a meter in size, are around us every day. Although they are tiny, they can benefit human health, as in some innovative early cancer treatments, but ...
'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.
