By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanoparticles. According to news reporting originating in Brno, Czech Republic, by NewsRx journalists, research stated, "We have investigated the absorbed power in a single gold or silver metallic nanoparticle together with the optical force acting upon it if the particle is illuminated by two counter-propagating plane waves forming a standing wave. We have used the Generalized Lorenz-Mie theory (GLMT) and considered the incident wavelengths 250 nm
The news reporters obtained a quote from the research from the Institute of Science, "However, in the case of a metallic object this phenomenon occurs for considerably smaller particles and the conditions change considerably with the illuminating wavelength especially near the localized surface plasmon resonances. Similarly, we have found that the absorbed heat does not change with the position of the particle in the standing wave for certain wavelengths and particle sizes."
According to the news reporters, the research concluded: "These sizes generally differ from those giving zero optical force and, therefore, the particle can be trapped at the intensity maximum or minimum and in both cases its heating is maximal or minimal depending on the particle size."
