For its vital role in maintaining cellular activity and survival, mitochondrion is highly involved in various diseases, and several strategies to target mitochondria have been developed for specific imaging and treatment. Among these approaches, theranostic may realize both diagnosis and therapy with one integrated material, benefiting the simplification of treatment process and candidate drug evaluation. A variety of mitochondria-targeting theranostic agents have been designed based on the differential structure and composition of mitochondria, which enable more precise localization within cellular mitochondria at disease sites, facilitating the unveiling of pathological information while concurrently performing therapeutic interventions. Here, progress of mitochondria-targeting theranostic materials reported in recent years along with background information on mitochondria-targeting and therapy have been briefly summarized, determining to deliver updated status and design ideas in this field to readers.

Colorectal cancer (CRC) is a major cause of cancer-related death, with poor outcomes at advanced stages due to metastasis and limited early detection. Photodynamic therapy (PDT), which relies on reactive oxygen species (ROS) to kill tumor cells, is promising but limited by hypoxia and short ROS diffusion distances. Here, we report Ir-EA, a novel cyclometalated Ir(III) complex with enhanced mitochondrial targeting and dual ROS generation capability, effective under both oxygen-rich and hypoxic conditions.

Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer. There are very few targeted treatment options with satisfactory therapeutic indexes for TNBC. Although chemotherapy is the principal treatment modality for TNBC, its effectiveness is significantly compromised by low chemosensitivity in the TNBC patient population.

The development of mitochondria-targeting fluorescent compounds with theranostic potential for tumor cells remains a topic of great interest. Inspired by previously reported delocalized lipophilic cations (DLCs) based on styryl dye framework, we introduce a series of seventeen novel styrene dyes, several of which exhibit enhanced optical properties compared to their parent compounds. Most dyes display strong Stokes shifts (104-112 nm), primarily due to the indolyl chromophore, with minimal influence from other substituents.

Pro-inflammatory photodynamic therapy (PDT) holds immense potential to ignite robust and long-lasting systemic anti-tumor immune responses. However, the limited penetration depth of conventional ultra violet (UV)-visible irradiation and the tumor hypoxia microenvironment significantly constrain the efficacy of immune-regulatory PDT. Here, a mitochondria-targeting enhanced nanoplatform (NZ) is reported, activated by near-infrared (NIR) light-driven PDT, to address these challenges and amplify systemic anti-tumor immunity.

Functionalizing nanoparticles with peptides (3-30 amino acids) reduces premature clearance and increases colloidal stability and targeting capacity of cancer therapeutics. Glutamate/lysine-rich zwitterionic and hydrophilic/neutral peptides minimize reticuloendothelial digestion of nanomedicine through reducing particle hydrophobicity and depressing plasma anti-PEG immunoglobulin that disrupts the PEG-based particle stealth. Anionic peptides negate protein corona formation and subsequent particle aggregation in vivo enabling efficient nanoparticles biodistribution and drug targeting by facilitating their endothelial/extracellular matrix pore diffusion.
