Abstract

Go for gold: As-prepared insulin-Au nanoclusters (NCs) show intense red fluorescence, excellent biocompatibility, and preservation of natural insulin bioactivity in lowering the blood-glucose level. Their versatility in applications is demonstrated by fluorescence imaging, X-ray computed tomography, and insulin-inhibitor interactions (see picture; IDE=insulin-degrading enzyme).
