The chemical construction of dispersed CdS nanoparticles within the polypeptide cage of apoferritin is demonstrated to be possible by a multistep synthetic route, as shown schematically in the Figure. Ferritin‐induced nucleation of CdS clusters (squares) is followed by reaction with excess sulfide to give CdS–ferritin. Such biocompatible nanoparticles might find uses as tunable photochemical agents for diagnosis, sensing, and drug delivery.
