    Abstract

    In this work, a novel layered double hydroxide (LDH)-based multifunctional nanoplatform was built for synergistic temperature photothermal therapy (PTT)/chemotherapy. The platform was modified using the peptide B3int to target cancer cells with overexpression of integrin αvβ3. Indocyanine green (ICG) and doxorubicin (DOX) were loaded into the nanocarrier (LDH-PEG-B3int NPs) to form a system having a high DOX drug loading (18.62%) and a remarkable photothermal conversion efficiency of 25.38%. It also showed pH-responsive and near-infrared (NIR)-triggered DOX release. In vitro and in vivo studies indicated that the anti-tumor activity of the combined delivery system was significantly higher than that of a single delivery system. This co-delivery nanosystem may be helpful for future application in the clinical treatment of cancer.
