Technique Simplifies Creation of Pure Colloidal Crystals

In an article published online July 21 in the journal Nature Communications, Panagiotopoulos and colleagues propose that pure photonic crystals could be created from a mixture in which colloidal particles are dispersed in a polymer melt. The research team, led by Thanos Panagiotopoulos, Susan Dod Brown Professor of Chemical and Biological Engineering, included CBE graduate student Nathan Mahynski, and Prof. Sanat K. Kumar and Postdoctoral Associate Dong Meng from Columbia University.  For more information, see the research article, “Stabilizing colloidal crystals by leveraging void distributions”, or the story posted on the Princeton University homepage.
