image: Digital photo of an EV-CLUE chip highlights the variable iridescent colors displayed by the microarray of 3D S-shaped wavy stripes patterned inside each microreactor. These micro-stripes were self-assembled from uniform nanoparticles, which create a regularly packed nanostructure that causes light scattering and interference to intensify different colors at certain angles, in a way similar to the iridescence of natural opals. This material relates to a paper that appeared in the Jun. 10, 2020, issue of Science Translational Medicine, published by AAAS. The paper, by P. Zhang at University of Kansas in Lawrence, KS; and colleagues was titled, "Molecular and functional extracellular vesicle analysis using nanopatterned microchips monitors tumor progression and metastasis." view more
