The cluster of tiny blue stars shows zinc oxide crystallized in the presence of gold nanoparticles. In the expanded image we see the star’s broken arms in blue, with gold in the center, in yellow. The images were made using scanning electron microscopy with field effect transistors, magnified 80 thousand times and digitally colored by Eder Guidelli, doctoral candidate at the Ribeirão Preto Faculty of Philosophy, Science and Languages and Literature (FFCLRP) of the University of São Paulo (USP). Guidelli, under his advisor, Oswaldo Baffa, is studying the applications of nanotechnology in medical physics to develop nanomaterials for use in X-ray detection. The images were finalists in the Science as Art competition at the 2013 Materials Research Society Fall Meeting in Boston.
