Channels and Chambers Lead to Better Function in Nanoparticles (2 of 2) (image) American Association for the Advancement of Science Share Print E-Mail Caption (Left) False-colored transmission electron microscopy image of a multicompartment mesoporous silica nanoparticle (mc-MSN) showing four branches emanating from the core. (Right) Corresponding model of the mc-MSN. By distinguishing the different compartments, multiple drugs could be potentially loaded on a single particle and released on a different time scale. This image relates to a paper that appeared in the April 19, 2013, issue of Science, published by AAAS. The paper, by Teeraporn Suteewong at Cornell University in Ithaca, NY, and colleagues was titled, "Multicompartment Mesoporous Silica Nanoparticles with Branched Shapes: An Epitaxial Growth Mechanism."
