摘要：
We report self-assembly of double hydrophilic block copolymer poly(acrylic acid-b-N-isopropylacrylamide) in aqueous solution. Self-assembly of calcium ions chelated complex micelles upon mineralization reaction forms calcium carbonate (CaCO3) sphere. High porosity on CaCO3 spheres can accommodate a large amount of anticancer drug (doxorubicin) and achieve sustainable drug release. (C) 2018 Elsevier B.V. All rights reserved.
