Abstract Phototherapy, including photodynamic therapy (PDT) and photothermal (PTT), has attracted wide attention in tumor treatment. However, the hypoxic microenvironment heat shock proteins produced by cells significantly reduce their efficacy. Developing effective phototherapy agents that have high reactive oxygen species generation efficiency conversion (PCE) while simultaneously utilizing is of great importance. Here, a thienothiophene‐benzopyran derivative, BTPIC4F‐C10 designed synthesized, with near‐infrared (NIR) absorption fluorescence. Then lipid nanoparticles (LipBFCA NPs) which encapsulated phospholipid bilayer together hypoxia‐activated prodrug banoxanthrone (AQ4N) are constructed for NIR‐II fluorescence imaging‐guided synergistic PDT/PTT/chemotherapy immune activation. Under 808 nm laser irradiation, LipBFCA NPs singlet quantum yield 20.2% PCE 78.8%. With ultra‐high photon energy utilization 99%, an excellent effect. The environment caused can further activate AQ4N to transform into chemically toxic AQ4 radicals kill cells. Moreover, induce immunogenic cell death, release tumor‐associated antigens, responses. This work provides new way clinical application imaging guiding diagnosis

Abstract Two‐photon excitation (2PE) represents substantial advantages in biophotonics over traditional one‐photon (1PE), offering enhanced spatial resolution and deeper tissue penetration capabilities. Since its introduction the 1990s, two‐photon excited microscopy has spurred rapid emergence of novel 2PE‐based applications, including photodynamic therapy (PDT) targeted release biologically active agents. This review first elucidates fundamental principles 2PE before comprehensively examining evolution photosensitizers (PSs) for PDT (2P‐PDT), covering both nanomaterials small molecules, categorized based on their respective characteristics. Additionally, it explores advancements PS development integrating 2P‐PDT with other therapeutic modalities (e.g., photothermal therapy, chemotherapy, immunotherapy, gene etc.). Subsequent sections provide an overview photoactivatable compounds absorption properties controlled various agents drugs, genes, gasotransmitters), emphasizing potential anticancer applications. Last, a deep discussion deciphers prospects challenges 2P‐mediated cancer treatment, particularly concerning clinical translation.

A series of dinuclear Ir(III) complexes have been constructed for enhanced photodynamic and photothermal therapy (PDT PTT) cisplatin-resistant non-small-cell lung cancer. They enter cells via caveolar endocytosis, target mitochondria but not nuclear, generate both singlet oxygen superoxide anion, release heat when exposed to infrared (IR) irradiation, thus inducing reactive species (ROS)-associated cell disruption thermal ablation. The IR-generated ROS can further activate caspases, triggering apoptosis. Additionally, the deplete intracellular glutathione, lead lipid peroxidation, induce ferroptosis. selected complex

Abstract Despite the advent of various medical interventions for cancer treatment, disease continues to pose a formidable global health challenge, necessitating development new therapeutic approaches more effective treatment outcomes. Photodynamic therapy (PDT), which utilizes light activate photosensitizer produce cytotoxic reactive oxygen species (ROS) eradicating cells, has emerged as promising approach due its high spatiotemporal precision and minimal invasiveness. However, widespread clinical use PDT faces several challenges, including inefficient production ROS in hypoxic tumor microenvironment, limited penetration depth biological tissues, inadequate accumulation photosensitizers at site. Over past decade, there been increasing interest utilization photofunctional transition metal complexes applications their intriguing photophysical photochemical properties. This review provides an overview current design strategies used innovative phototherapeutics, aiming address limitations associated with achieve The challenges future perspectives on translation are also discussed.
