The team of Koji SUGOKA at RIKEN Photonics Engineering Research Area has developed a technology for depositing metal thin films on a 3D microfluidic structure inside a glass microchip. Within the closed space of „electrofluidics“ fabricated by this technology, it was possible to control the 3D movement directions of Euglena.
