What looks like the movement of strips of woven fabric is actually a pile of iron oxide nanoparticles. This is a type n semiconductor, used to capture photons (light particles) for transformation into electric energy. The photos of the nanoparticle have been taken with an extremely high resolution electron microscope and afterwards colored by researchers or technicians. “The habit of painting photos of nanometric formations has given rise to nanoart, for which there is now guaranteed room in gallery exhibitions worldwide,” says Elson Longo, coordinator of the Interdisciplinary Laboratory of Electrochemistry and Ceramics at Paulista State University, Araraquara campus. The photo, named Spirals, was exhibited at a show in New York in 2011.
