Researchers at Washington University in St. Louis Use Microneedle Patch with Fluorescent Nanolabels to Detect Biomarkers in Skin’s Interstitial Fluid

Painless technology could one day replace some phlebotomy blood draws as the go-to specimen-collection method for clinical laboratory testing and health monitoring Clinical laboratories have long sought a non-invasive way to do useful medical laboratory testing without the need for either a venipuncture or a needle stick. Now engineers at the McKelvey School of Engineering at Washington University in St. Louis in Missouri have developed a disposable microneedle patch that one day could be a...
