In Situ Nanozyme‐Amplified NIR‐II Phototheranostics for Tumor‐Specific Imaging and Therapy

The discovery of near‐IR‐II (NIR‐II) tumor phototheranostics holds a great promise for use in nanomedicine on account of its enhanced penetration depth, high spatial resolution, and noninvasiveness. However, contemporary “always on” phototherapeutic agents often have many undesirable side effects that hinder their clinical trial progress. To overcome this dilemma, an in situ nanozyme‐amplified chromogenic nanoreactor by loading...
