Scientists grow solar cell components in tobacco plants

(PhysOrg.com) -- Over billions of years, plants have evolved very efficient sunlight-collecting systems. Now, scientists are trying to harness the finely tuned systems in tobacco plants in order to use them as the building ...

DNA 'Trojan horse' smuggles drugs into resistant cancer cells

Researchers at The Ohio State University are working on a new way to treat drug-resistant cancer that the ancient Greeks would approve of—only it's not a Trojan horse, but DNA that hides the invading force.

Cancer-fighting nanorobots programmed to seek and destroy tumors

In a major advancement in nanomedicine, Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences, have ...

Electric fields remove nanoparticles from blood with ease

Engineers at the University of California, San Diego developed a new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood. The technology could serve as a ...

Flu virus shells could improve delivery of mRNA into cells

Nanoengineers at the University of California San Diego have developed a new and potentially more effective way to deliver messenger RNA (mRNA) into cells. Their approach involves packing mRNA inside nanoparticles that mimic ...

First Direct Images of Carbon Nanotubes Entering Cells

For the first time, scientists have directly imaged carbon nanotubes entering and migrating within human cells, determining as a result that whether the nanotubes cause cell death depends on the dose and exposure time. The ...

Chemists find fungal shrapnel in the air

In a discovery that has implications for our understanding of the air we breathe, UCI chemists report that they've found nanoscale fragments of fungal cells in the atmosphere. The pieces are extremely small, measuring about ...
