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

Abstract

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.
