Wereley Biochip (IMAGE) Purdue University 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 <i>Shewanella oneidensis</i>. <p>A publication-quality image is available at <a target="_Blank"href="http://www.purdue.edu/uns/images/2013/wereley-biochip.jpg">http://www.purdue.edu/uns/images/2013/wereley-biochip.jpg</a>.
