A new technology uses human teardrops to spot disease

Chinese scientists at Wenzlou Medical University have    “devised a new way to capture the sacs from tiny volumes of tears. First, the researchers collected tears from study participants. Then, the team added a solution containing the tears to a device with two nanoporous membranes, vibrated the membranes and sucked the solution through. Within minutes, the technique lets small molecules escape, leaving the sacs behind for analysis.”  The sacs are tear exosomes.       MORE
