The engineers coated gold nanoparticles with titanium dioxide and exposed the material to UV, visible, and infrared light and studied how electrons jump from gold to the material. The researchers ...

Metal nanoparticles, particularly noble metals like gold and silver, exhibit unique optical properties due to their surface plasmon resonance (SPR). UV-Vis spectroscopy can probe the SPR band, which ...

The visible light excites the electrons in the gold nanoparticles and initiates reactions that culminate in charge separation on the silver chloride nanowires. Tests have already shown that gold ...

Researchers have published the first example of a synthetic sugar detection test for snake venom, offering a new route to rapid diagnosis and better antivenoms.

Gold nanorods possess the unique property of being able ... aspect ratio and rod quality for a group of nanoparticles. However, UV/Vis offers limited information regarding actual size. TEM and SEM are ...

Gold nanospheres play a pivotal role in point-of-care diagnostics, but manufacturing them at scale with uniform size and ...

Scientists from the University of Bath (UK) and Northwestern University (USA) have developed a new type of sensor platform using a gold nanoparticle array, which is 100 times more sensitive than ...

Some of the newest medical treatments out there require gold—minute rods and spheres wrapped in gold. These nanoparticles ... cells to millisecond pulses of visible light, which heated up ...

Reports state that colloidal gold nanoparticles have been utilized for centuries by artists for their vibrant colors, which are produced by their interaction with visible light. However, only in the ...
