What's going on with nanomedicine?

Back in the spring of 2015, one of our Nanowerk Spotlights asked the question: 'Has nanomedicine lived up to its promise?' The answer then was that, judging by research activity and funding, the field of nanomedicine has been very fertile; however, by using the yardstick of clinical success and paradigm shifts in treatment, the results appear quite a bit more modest. So here we are, at the end of 2020, and the answer to that same question still is inconclusive. To address this problem, researchers now propose the creation of new nanomedicine design criteria.
