Our lab has developed a novel platform for droplet sorting that can be used to sort enzymes by activity, and cells by metabolism. It is a passive technique that utilizes no excitation laser, detector, active sorter and related electronics, or fluorescent labels. It presents a robust way to sort enzyme libraries for screening and sort cancer cells by a defining characteristic, their aberrant metabolism. The technique also enables the isolation of activated T-cells prior to the display of cellular surface markers. The isolation of activated T-cells in minutes rather than hours can have broad usage as a biotechnology tool and for the study and selection for immunology and immunotherapy.
