For the last decade, scientists around the globe have worked to develop and refine highly fluorescent nanoparticles that light up when bathed with laser light, enabling scientists to pinpoint the location of an individual molecule inside a living cell or tissue.Recently, Clemson chemists developed novel, highly fluorescent nanoparticles called “polymer dots” that can be attached to individual proteins, DNA or invading microbes. According to chemist Jason McNeill, the polymer dot particles are hundreds or thousands of times brighter than conventional fluorescent dyes.
The two chemists credit the highly collaborative, multidisciplinary environment at Clemson as a key factor in this new frontier in nanotechnology.
Details of the nanoparticle technology were recently presented at the 2007 national meeting of the American Chemical Society in Boston and have been published in the Journal of the American Chemical Society, Langmuir and in the Journal of Physical Chemistry. END
