An H2O2-responsive nanocarrier for dual-release of platinum anticancer drugs and O2: controlled release and enhanced cytotoxicity against cisplatin resistant cancer cells

Abstract

Synergistic release of platinum anticancer drugs and O₂ can be achieved in an H₂O₂-responsive nanocarrier incorporated with catalase. Such a system combines the advantages of chemotherapy and oxygen therapy and demonstrated improved therapeutic efficacy against cisplatin resistant cell lines which often appear to be in hypoxia.
