DNAzyme-based sensors remain at the forefront of metal-ion imaging efforts, but most lack subcellular precision necessary to their applications in specific organelles. Here, we seek overcome this limitation by presenting a biosensor technology for spatiotemporally controlled metal ions mitochondria. A DNA nanodevice was constructed integrating an optically activatable DNAzyme sensor and upconversion nanoparticle with organelle-targeting signal. We exemplify that approach allows mitochondria-specific Zn2+ living cells near-infrared light-controlled manner. Based on this, system is used monitoring mitochondrial during drug treatment cellular model ischemia insult. Furthermore, employed assess dynamic change pharmacological interventions injury cell toxicity. This method paves way engineering investigate pathophysiological roles level.

Hepatic ischemia–reperfusion (I/R) injury accompanied by oxidative stress is responsible for postoperative liver dysfunction and failure of surgery. However, the dynamic non-invasive mapping redox homeostasis in deep-seated during hepatic I/R remains a great challenge. Herein, inspired intrinsic reversibility disulfide bond proteins, kind reversible redox-responsive magnetic nanoparticles (RRMNs) designed imaging both oxidant antioxidant levels (ONOO–/GSH), based on sulfhydryl coupling/cleaving reaction. We develop facile strategy to prepare such MRI nanoprobe via one-step surface modification. Owing significant change size response, sensitivity RRMNs greatly improved, which enables monitor tiny injury. Notably, can non-invasively visualize tissue slice living mice. Moreover, this not only report molecular information about degree but also provide anatomical where pathology occurred. The probe promising accurately facilely monitoring process, accessing developing powerful precise treatment.
