Last Monday, Rüdiger Trojok made a short stop at realraum on his way through Graz and gave a live Demo of OpenDrop, a cool BioHacking Hardware project of his that he has spent more than the last two years working on.
Opendrop, moves tiny drops of fluid (preferably water based) across a surface by way of electrostatic force manipulation.
It can arbitrarily mix or split drops of various chemicals or from various samples. Making it the ultimate microfluidic chemistry or molecular biology lab.
Or one can just use it to … you know … play pacman with colored drops of water.
Whatever the usecase, watching the tiny droplets zoom across the foliated surface, moved by an invisible force is quite awesome to watch. Science seldom looks so cool!
