Jahn-Teller distortion-engineered self-propelled nanorobots for mitochondrial targeting and bioenergetic disruption in tumor therapy.

ABSTRACT: Mitochondrial metabolism plays a pivotal role in tumor progression, yet effective therapeutic targeting remains constrained by limited tissue penetration and lack of spatiotemporal control. Herein, we present Jahn-Teller distortion-engineered, self-propelled nanorobots (IDP@Z@AP) that integrate catalytic oxygen generation, mitochondria-targeted drug delivery, and real-time 3D NIR-II photoacoustic (PA) imaging for precision tumor therapy. The nanorobots are fabricated by co-encapsulating a NIR-II photothermal agent (IR1048) and a mitochondria-targeting chemotherapeutic (DOX-TPP) within a ZIF-8 framework, followed by in situ anchoring of ultrasmall AuPt bimetallic nanozymes. Pt-induced Jahn-Teller distortion modulates the electronic structure of AuPt, enhancing glucose oxidase- and catalase-
