We describe a technique that uses biocompatible chemical agents to enhance both the sensitivity and the resolution of <i>in vivo</i> imaging with low-level light-emitting probes. We demonstrate experimentally, with chemiluminescence (CL) imaging <i>in vitro</i> as an example, that the detected intensity of CL from treated 3-mm-thick skin tissue is approximately fivefold stronger than that from untreated skin. The spatial resolution correspondingly increases approximately threefold.
