Fanqing Frank Chen, Ph.D., at the Lawrence Berkeley National Laboratory, led a group of investigators that created a nanoplasmonic ruler designed to measure changes in DNA length quantitatively and instantly. The ruler uses gold nanoparticles and relies on the fact that precious metal nanoparticles emit light at well-described wavelengths of light in a manner that is highly influenced by the exact physical and chemical environment surrounding the particle.
