Microcapsules have been widely used in medicine,food,cosmetics and daily necessities.Especially,the smart degradable microcapsules which served as carriers for controlled release of drugs,DNA,RNA and proteins have got more and more attentions.In this paper,a novel disulfide bond crosslinking degradable polyelectrolyte microcapsule was prepared via layer-by-layer(LBL)method.MnCO3 microparticles and 3,3′-Dithiodipropionic acid(DPA)were employed as templates and wall materials,respectively.The results show tha...
