Caption: Researchers have demonstrated a new technology that combines a laser and electric fields to create tiny centrifuge-like whirlpools to separate particles and microbes by size, a potential lab-on-a-chip system for medicine and research. Here the technique is used to collect a bacterium called Shewanella oneidensis.
