Magnetic Droplets Self-Assemble on Water-Repellent Surfaces
Added Jul 23, 2013 | Rate View top rated
Researchers from Finland's Aalto University and France's Paris Tech have placed water droplets containing magnetic nanoparticles on superhydrophobic surfaces and made them align in various static and dynamic structures using periodically oscillating magnetic fields. This is the first time reversible switching between static and dynamic self-assembly has been demonstrated. The self-assembly process is very interesting for scientists and industry because many natural systems rely on self-assembled structures and they can further inspire technological applications. "We are conducting this line of research because it opens up a way to create new responsive and intelligent systems and materials," said Dr. Robin Ras of Aalto University.
