Abstract:
Gold and gold-based alloy nanocrystals (NCs) have been widely used in the field of photothermal therapy (PTT). However, the synthesis of multimodal nano-agents for precise and efficient PTT in the second near infrared (NIR-II) region remains a great challenge. Herein, Au3Cu TPNCs were developed as a powerful platform for multimodal image-guided photothermal therapy with significant therapeutic effects and good metabolizability in the NIR-II region.
