This phenomenon arises as incident light interacts with surface electrons and is scattered. It forms the basis of many of the applications of nanoparticles in photonics, for instance.<\/p>\n<p>The team explains that the approach is more convenient and less time-consuming than other techniques. They add that it is possible to use the technique in real-world environments rather than requiring pristine laboratory conditions and a scanning electron microscope. And they have now validated their size estimates against precise measurements and claim that an error margin of less than 5 nm is possible.<\/p>\n<p>&#8216;I do believe this work represents a very elegant new method for estimating gold nanoparticle size according to their light scattering optical properties,&#8217; <strong>Qun Huo of the University of Central Florida<\/strong> tells Chemistry World. Huo specialises in the synthesis and properties of nanoparticles. &#8216;The principle behind the method has been known within the community for a while,&#8217; she adds. &#8216;However, the authors of this paper have managed to introduce mathematical software to analyse the optical properties and so correlate the information with nanoparticle size.
