An engineered variant of the plant virus, Cowpea mosaic virus, can template the controlled fabrication of silica nanoparticles of ≈30-nm diameter under environmentally benign conditions at ambient temperature and in aqueous solvent. This is the first reported mineralization of the external surface of a cage-like viral bionanoparticle (see image).
