A facile way to prepare mesoporous spherical calcites controlled by chondroitin sulfate for shape and carboxymethyl chitosan for size†
Abstract
Inspired by biomineralization, monodispersed spherical calcites coated with a layer of polymer were obtained with the cooperative role of two polymers: carboxymethyl chitosan for size control and chondroitin sulfate for shape control. These calcites can be regarded as mesocrystals aggregated by nanoparticles with a mesoporous structure, and therefore have potential application as drug delivery systems.
