Abstract Metastasis, the leading cause of mortality in cancer patients, presents challenges for conventional photodynamic therapy (PDT) due to its reliance on localized light and oxygen application tumors. To overcome these limitations, a self‐sustained organelle‐mimicking nanoreactor is developed here with programmable DNA switches that enables bio‐chem‐photocatalytic cascade‐driven starvation‐photodynamic synergistic against tumor metastasis. Emulating compartmentalization positional assembly strategies found living cells, this nano‐organelle reactor allows quantitative co‐compartmentalization multiple functional modules designed self‐illuminating chemiexcited PDT system. Within space‐confined nanoreactor, biofuel glucose converted hydrogen peroxide (H 2 O ) which enhances luminol‐based chemiluminescence (CL), consequently driving generation photochemical singlet ( 1 via resonance energy transfer. Meanwhile, hemoglobin functions as synchronized supplier both oxidation PDT, while also exhibiting peroxidase‐like activity produce hydroxyl radicals (·OH). Crucially, keeps switching off normal tissues, on‐demand activation tumors through toehold‐mediated strand displacement. These findings demonstrate self‐sufficient precise striking tumors, promising paradigm managing highly metastatic cancers.

Cancer has emerged as a formidable challenge in the 21st century, impacting society, public health, and economy. Conventional cancer treatments often exhibit limited efficacy considerable side effects, particularly managing advanced stages of disease. Photodynamic therapy (PDT), contemporary non-invasive therapeutic approach, employs photosensitizers (PS) conjunction with precise light wavelengths to selectively target diseased tissues, inducing generation reactive oxygen species ultimately leading cell apoptosis. In contrast conventional therapies, PDT presents lower incidence effects greater precision targeting. The integration intelligent nanotechnology into markedly improved its effectiveness, evidenced by remarkable synergistic antitumor observed utilization multifunctional nanoplatforms PDT. This paper provides concise overview principles underlying PS PDT, while also delving nanomaterial-based context treatment.

Photodynamic therapy (PDT) holds promise as a cancer treatment modality due to its potential for enhanced precision and safety. To enhance deep tissue penetration minimize adsorption phototoxicity, developing photosensitizers activated by second near-infrared window (NIR-II) light shows significant potential. However, the efficacy of PDT is often impeded tumor microenvironment hypoxia, primarily caused irregular vasculature. Fortunately, stimulator interferon genes (STING) pathway, known immune activation, has been linked vasculature normalization. In this study, we developed nanoplatform (Fe-THBQ/SR) loading STING agonist (SR-717) into an iron-tetrahydroxy-1,4-benzoquinone (Fe-THBQ) metal–organic framework. Fe-THBQ was proven be effective NIR-II photosensitizer, generating numerous reactive oxygen species (ROS) under 1064 nm laser irradiation. These ROS downregulated heat shock protein expression, consequently promoting mild-photothermal (mild-PTT), facilitated ferroptosis depleting glutathione (GSH)/glutathione peroxidase 4. Moreover, Fe-THBQ/SR released SR-717 upon GSH stimulation, synergizing with ROS-mediated double-stranded DNA leakage activation. This process contributed normalization hypoxia alleviation, thereby enhancing efficacy. Overall, presented versatile single-laser-triggered mild-PTT simultaneously coupled it activation form reinforcing cycle. synergistic enhancements increased immunogenicity cells, remodeled immunosuppressive microenvironment, T lymphocyte infiltration, improved therapeutic outcomes.

Photodynamic therapy (PDT), a promising treatment modality, employs photosensitizers to generate cytotoxic reactive oxygen species (ROS) within localized tumor regions. This technique involves administering photosensitizer followed by light activation in the presence of (O 2 ), resulting ROS production.
