... up to three or four drugs.
The new technique takes advantage of the fact that when gold nanoparticles are exposed to infrared light, they melt and release drug payloads attached to their surfaces. ...
... have found that packing small interfering RNA (siRNA) molecules onto the surface of a gold nanoparticle can protect siRNAs from degradation and increase their ability to regulate genes involved in ...
... cancer. In tests using mice, the resulting nanospheres were found to be significantly more effective than solid gold nanoparticles due to much stronger near infrared-light absorption of the hollow ...
Technique uses gold nanoparticles and DNA in new test for prostate cancer 300 times more sensitive than commercial assays
... a hole in its protective membrane and killing it. The key to their approach? Stripes.
The team found that gold nanoparticles coated with alternating bands of two different kinds of molecules can ...
... . However, high magnification imaging showed the band was in fact, a mass of gold nanoparticles and nanoplates. These are identical to those being manufactured in laboratories around the world for ...

... nanoparticles, the research team is collaborating with other groups at Georgia Tech to determine how peptide-directed gold nanoparticles and nanohydrogels might also be used in fighting cancer.
... . In this project, Hutchings' group carried out the fabrication and catalytic testing of the gold nanoparticles, and the characterization of the catalyst using x-ray photoelectron spectroscopy (XPS). ...
... Company, a company that is in the beginning stages of producing environmentally friendly gold nanoparticles. The company will focus on the development, commercialization and worldwide supply of gold ...
Gold nanoparticles are everywhere. They are used in cancer treatments, automobile sensors, cell phones, blood sugar monitors and hydrogen gas production. However, until recently, scientists couldn't ...
... in three dimensions. To do so, the team uses gold nanoparticles, which can be placed on single-stranded DNA, ... in addition to closed rings. A 10 nanometer gold particle however, exerted greater steric ...
Using tiny gold particles and infrared light, MIT researchers have developed a drug-delivery system that allows multiple drugs to be released in a controlled fashion.
