Measuring nanoparticles with light

A colourful way to size up nanoparticles – A property of nanoparticles commonly exploited in a wide range of applications can be turned on the nanoparticles themselves to give scientists an estimate of the particles' size. Researchers in China have now developed a straightforward light-scattering technique to estimate the size of gold nanoparticles in the 35 to 110nm range. Reference: C Jing et al, Anal.
