aptamer sensors patched up My astrobiology co-author Kevin Plaxco has been pioneering the development of biosensors based on aptamers (the artificially generated DNA equivalent of antibodies) for many years now and every once in a while I write about the progress in this fascinating field. Now the work has reached its first clinical trial, so I wrote a news story for Chemistry World to help spread the word. The news story is out now: World first for clinical trial of skin patch to monitor therapeutic drugs in real time Chemistry World 5.2.2026 Source: © Marsilea A Booth et al/Springer Nature America 2026 Previous episodes in this serie are listed here.
