Abstract
A virion-constrained nanoparticle of the invention comprises a shell of a virion coat protein(s) that encapsulates a core non-viral material, which is organic, inorganic or organometallic in nature. A particularly preferred virion coat is that of cowpea chlorotic mottle virus (CCMV). Encapsulation of a desired particle is effected by adjusting reaction conditions, e.g., by lowering the pH of a solution containing the virion protein and the non-viral substance. Processes for producing the virion-constrained nanoparticles of the invention are also described.
