Sono‐Controllable and ROS‐Sensitive CRISPR‐Cas9 Genome Editing for Augmented/Synergistic Ultrasound Tumor Nanotherapy

The potential of the cluster regularly interspaced short palindromic repeat (CRISPR)-associated protein 9 (Cas9)-based therapeutic genome editing is severely hampered by the difficulties in precise regulation of the in vivo activity of the CRISPR-Cas9 system. Herein, sono-controllable and reactive oxygen species (ROS)-sensitive sonosensitizer-integrated metal-organic frameworks (MOFs), denoted as P/M@CasMTH1, are developed for augmented sonodynamic therapy (SDT) efficacy using the genome-editing technology. P/M@CasMTH1 nanoparticles comprise singlet oxygen (
