Pulsed Laser Irradiation Enhances Nanoplate Properties

Facebook Twitter LinkedIn Email Comments
When gold-coated silver nanoparticles are irradiated with a pulsed laser, the heat from the laser enables silver ions to escape through the gold coating, thus preserving the strong antibacterial effect of the silver. When gold-coated silver nanoplates are irradiated with a pulsed laser, they change shape into a sphere and release silver ions which produces a strong antibacterial effect. Courtesy of Dr. Takuro Niidome. Silver nanoparticles (AgNPs) are known to have antibacterial properties; but they also have a propensity to conglomerate, which reduces their antibacterial attributes....Read full article
