Nanocrystals are small collections of several hundred to hundred thousand atoms arranged in a crystal matrix. Quantum dots are nanocrystals made of semiconductors, and the several hundred atoms act like one giant molecule with regards to their electrons with variations in energy levels due to the size of the dot. The smaller the dot, the higher photon energy released during fluorescence. This video was compiled from fluorescing colloidal quantum dots of different sizes excited by an argon laser. The dots are invisible (with one exception in a microscope at 2:14) but they produce the bright colors in the beam. The bits of bright blue flashes are dust particles in the solutions. |

 Stuart Lindsay, Arizona State University Regents’ professor and director of the Biodesign Institute’s Center for Single Molecule Biophysics, has just released the first comprehensive guide to a tiny world a million times smaller than a single grain of sand. "Introduction to Nanoscience" (published by Oxford University Press) provides readers with an overview of an emerging discipline which has in recent years, produced remarkable achievements in areas as varied as DNA sequencing, molecular machinery, nanocrystals and microscopy.
Nanonet foundation would like to thank Professor Stuart Lindsay from ASU for letting us use his article and videos links.
