Nanoceria decorated flower-like molybdenum sulphide nanoflakes: an efficient nanozyme for tumour selective ROS generation and photo thermal therapy.

We report nanoceria (NCeO2) decorated flower-like MoS2 nanoflakes as a nanozyme for cancer photothermal therapy (PTT). They exhibited enzyme-like activity for selectively killing tumor cells by ROS induction. The NCeO2 decoration significantly improved the photoconversion efficiencies (PCEs) of MoS2 nanoflakes when a NCeO2 concentration of ≤0.5 mg mL-1 was used for synthesis. The novel material demonstrated here showed high photostability and PCE, without any systemic toxicity for cancer PTT.
