Plasmonic gold nanoparticles make pinpoint heating on demand possible.
Scientists have developed a system to quickly detect trace amounts of chemicals like pollutants, explosives or illegal drugs.
Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location.
DNA holds the genetic code for all sorts of biological molecules and traits.
New research at Rice University that seeks to establish points of reference between plasmonic particles and polymers might lead to smaller computer chips, better antennae and improvements in optical computing.
Using light-harvesting nanoparticles to convert laser energy into “plasmonic nanobubbles,” researchers at Rice University, the University of Texas MD Anderson Cancer Center and Baylor College of Medicine (BCM) are developing new methods to inject drugs and genetic payloads directly into cancer cells.
They look like fruit, and indeed the nanoscale stars of new research at Rice University have tasty implications for medical imaging and chemical sensing.
Take an ounce of lettuce, test it for 17 hours, and the results show whether that mainstay ingredient in green salads is contaminated with Salmonella, the food poisoning bacteria that sickens millions of people each year.
Chemists at Brown University have created a triple-headed metallic nanoparticle that reportedly performs better and lasts longer than any other nanoparticle catalyst studied in fuel-cell reactions.
