Researchers assemble patterns of micro- and nanoparticles

Researchers from the Department of Chemical Engineering at the Vrije Universiteit Brussel, Riga Technical University and the MESA+ Institute at the University of Twente have succeeded in arranging very small particles (10 µm to 500 nm, 10 to 100 times thinner than a human hair) in a thin layer without using solvents. This is a hugely important first step towards developing a new generation of sensors and electronics for a wide range of applications

"Common methods based on crystallising solutions are not as versatile as we would like. What’s more, previous dry methods were mainly effective on sticky surfaces, which limited their applications," says Ignaas Jimidar of the VUB. ...
