Synthesis of Uniform and Dispersive Calcium Carbonate

Jun 15, 2011· We have synthesized calcium carbonate nanoparticles (Ca-NPs) in the cavity of a cage-shaped protein, apoferritin, by regulating the electrostatic potential of the molecule. The electrostatic potential in the cavity was controlled by pH changes resulting from changes in the dissolved carbon dioxide (CO2) concentration in the reaction solution. Recombinant l-apoferritin was mixed with a
