A Universal One-Step Device to Safely and Painlessly Collect Blood

Donald Chickering and a team at Seventh Sense Biosystems in the U.S. are developing its Touch Activated Phlebotomy (TAP) platform to enable one-step blood collection in a safe, painless, and convenient manner. The device uses an integrated system of microneedles and vacuum capture of a blood sample for downstream analysis. TAP has the potential to expand access to diagnostic testing into underserved and hard-to-sample populations, while also improving safety and ease of collection.
