Polyelectrolyte multilayer microcapsules templated on spherical, elliptical and square calcium carbonate particles†
Abstract
Recent studies have revealed that a variety of shaped particles can interact with cells in a different way. Elongated particles can be effectively and quickly internalized intercellularly compared with other configurations. Herein we present the potential of fabrication of anisotropic polyelectrolyte multilayer capsules formed by coating spherical, ellipsoid-like and square calcium carbonate (CaCO3) particles. By varying the intermixing speed, time, pH value and ratio of initial ingredients during
