Hierarchical self-assembly of heparin-PEG end-capped porous silica as a redox sensitive nanocarrier for doxorubicin delivery

Hierarchical self-assembly of heparin-PEG end-capped mesoporous silica through host-guest interaction for trapping doxorubicin. The copolymer attached on PNS via disulfide bond which is rapidly cleaved in redox environment, and as a result a huge amount of doxorubicin will release.173
