Scientists in Taiwan are reporting development of a nanoparticle drug delivery system that shows promise as a potential way to administer insulin and perhaps other protein-based drugs by mouth rather ...

For those unfamiliar with the term, a "whispering gallery" is a round room designed in such a way that sound is carried around its perimeter - this allows a person standing on one side to hear words ...

This is a schematic presentation of plasmonic-enhanced two-photon fluorescence of a single emitter inside or outside of an individual gold nanoshell. The strategy of using metallic nanoparticles to ...

Researchers have successfully destroyed tumors of human brain cancer cells in the first animal tests of a minimally invasive treatment that zaps glioma tumors with heat. The researchers reported that ...

Scientists from four U.S. universities have created a way to use Rice University’s light-activated nanoshells as building blocks for 2-D and 3-D structures that could find use in chemical sensors, ...

Nanospectra’s AuroLase Therapy uses a combination of lasers and nanoparticles to destroy cancer tumors with heat. Because the nanoparticles — balls of silica encased in a thin shell of gold — are ...

A nanoshell to protect foreign enzymes used to starve cancer cells as part of chemotherapy has been developed by nanoengineers. Enzymes are naturally smart machines that are responsible for many ...

Lateral flow assays, also called immunochromatographic assays, identify or measure biomolecules in intricate samples like blood, saliva, urine, or other fluids to diagnose numerous medical conditions.

BUFFALO, N.Y. – A byproduct of landfilling, livestock farming, coal mining and other human activities, methane emissions are one of the key drivers of climate change. Yet for decades scientists have ...

Two-photon excitation fluorescence is growing in popularity in the bioimaging field but is limited by fluorophores' extremely low two-photon absorption cross-section. The researcher Dr. Guowei Lu and ...

HOUSTON -- (Feb. 1, 2011) -- Rice University bioengineers and physician-scientists at Baylor College of Medicine and Texas Children's Hospital have successfully destroyed tumors of human brain cancer ...
