High
reactive oxygen species (ROS) generation efficiency and induction
of targeted cell apoptosis are recognized as key objectives to achieve
a highly efficient strategy for cancer therapy with minimum side effects
of inflammatory reactions. However, it is still a challenge to realize
higher therapeutic efficiency with a cell apoptosis model. Herein,
we present strong upconversion luminescent biosafe cores derived from
Linde Type A (LTA) zeolites and modification with targeted/therapeutic
drugs for multimodal therapy, in which sonodynamic therapy (SDT) combined
with photodynamic therapy (PDT) increases therapeutic efficiency especially
in deep sites of tumor via producing cytoplasmic ROS and mitochondrial
superoxide and photothermal therapy (PTT) enhances PDT effects via
higher fluorescence resonance energy transfer (FRET) efficacy attributed
to an increased temperature. Furthermore, the transcriptomic analysis
reveals that cellular internalization of the nanosystem can lead to
tumor ablation via cell apoptosis. We expect that the multimodal therapy
based on LTA zeolite drug nanocarriers could be applied in the cancer
therapeutics in the near future.
