University of Oklahoma researchers have created a new drug delivery system that helps cancer cells take in much more of a ...

Of the many weapons science has come to offer in the fight against cancer, ones that are showing plenty of potential are gold nanoparticles. We have seen how these could be grown inside tumors to ...

Spherical and star-shaped gold nanoparticles (top) and colon cancer cells after approx. five hours of exposure to them (bottom, respectively). The photo in the bottom left corner proves that, despite ...

Though the sun produces more energy than we would ever need on Earth, current ...

Researchers have engineered tiny gold nanospheres that can soak up almost the entire spectrum of solar energy, promising a ...

A single gold nanoparticle tends to absorb within a narrow band. Much of its strongest response sits in visible wavelengths.

A new therapy involving laser light and sugar-coated gold nanoparticles can rapidly destroy slimy bacterial accumulations called "biofilms" that cause tooth decay and infect wounds—all without needing ...

Some key applications of gold nanoparticles include photonics, medicine and catalysis. 3 Gold nanoparticles have a high absorption cross-section in the visible and infrared regions, which can be tuned ...

Gold is a precious metal that has always fascinated humans. From Priam’s Treasure to the legend of El Dorado, gold —regarded as the noblest of metals— has been a symbol of splendour and wealth in many ...

The basic working principle of colorimetric sensing is colorimetry, which is a visible change in color that results from a chemical interaction between the sensing/detecting material and the target ...
