Researchers have demonstrated a new microfluidic sorting device that rapidly analyzes millions of biological reactions. Smaller than an iPod Nano, the device analyzes reactions a 1,000-times faster and uses 10 million-fold less volumes of reagent than conventional state-of-the-art robotic methods. The scientists anticipate that the invention could reduce screening costs by 1 million-fold and make directed evolution more commonplace in the lab.
