Summary: Due to deficiencies in specific accumulation at tumors and undesired activation in normal tissues, many photodynamic therapy (PDT) agents show off-target phototoxicity. To address this issue, activatable photodynamic nano-photosensitizers (nanoPSs) that generate reactive oxygen species (ROS) in response to tumor-associated or external stimuli have been developed. These nanoPSs are in an off-state during delivery and are only activated in targeted lesions, enhancing the accuracy and minimizing side effects. This review discusses the design, work principle, and therapeutic performance of PDT using activatable nanoPSs, categorized by different stimuli and composite materials.

Summary: This study introduces an organic polymer nanoenzyme (SPNK) with near-infrared (NIR) photoactivatable immunotherapeutic effects for photodynamic immunometabolic therapy. By generating singlet oxygen (O-1(2)) upon NIR photoirradiation, SPNK induces immunogenic cell death of cancer and degrades immunosuppressive kynurenine (Kyn), ultimately promoting effector T cell proliferation and infiltration, enhancing systemic antitumor T cell immunity, and inhibiting both primary and distant tumors in living mice.

Summary: This study developed a drug carrier consisting of hollow mesoporous silica nanoparticle (HMSNs) encapsulated with folic acid-modified bovine serum albumin (BSA-FA) for tumor targeting and controlled drug release. The carrier achieved specific intracellular drug delivery through folic acid and released the drug in response to intracellular conditions. The targeted and controlled drug release properties of the carrier make it a promising approach for cancer treatment.

Summary: This study reports a smart semiconducting polymer nano-immunomodulator that can achieve precise regulation of photodynamic immunotherapy for cancer in the acidic tumor microenvironment. The release of immunogenic factors and TLR7 agonist at the tumor site activates dendritic cells, leading to strong antitumor activities. Additionally, the nano-immunomodulator can directly eradicate tumors and induce immunogenic cancer cell death. This approach enhances systemic antitumor immune responses, resulting in inhibition of tumor growth and metastasis.

Summary: Cancer-associated fibroblasts (CAFs) are major components of the tumor-associated matrix and play a crucial role in tumor progression and immunosuppression. A new molecular pro-theranostic probe (FMP) with activatable fluorescence, photoacoustic imaging, and photodynamic therapy has been developed to specifically target CAFs. This probe shows efficient activatable phototoxicity towards CAFs and tumor cells, leading to complete regression of primary tumors and abscopal effects on distant tumors in a mouse model. Furthermore, when combined with PD-L1 checkpoint blockade immunotherapy, it also induces enhanced systemic immune responses and long-lasting tumor suppression in living mice.

Summary: Nanodynamic therapies using nanosensitizers triggered by various activators or reactions in tumor microenvironment have emerged as attractive strategies for treating deep-seated tumors. Mesoporous silica nanoparticles (MSNs) and MSNs-based hybrid nanoparticles are promising candidates for nanodynamic therapies due to their large surface area, high pore volume, biosafety, and easy surface modification. This review summarizes the antitumor mechanisms and latest progress in the construction, modification, and application of MSNs-based nanodynamic therapies, including photodynamic therapy, chemodynamic therapy, sonodynamic therapy, thermodynamic therapy, radiodynamic therapy, and electrodynamic therapy. The challenges and prospects for clinical applications of MSNs-based ROS-activated cancer treatments are also discussed.

Summary: Photodynamic therapy (PDT) is an efficient and minimally invasive cancer treatment method. However, current photosensitizers often exhibit dark toxicity and low tumor specificity. To address this issue, researchers have developed a series of acid-activatable photosensitizers for highly sensitive PDT of triple-negative breast tumors. These novel photosensitizers can be activated in an acidic environment to generate reactive oxygen species (ROS) and emit fluorescence. They are also modified with a poly(ethylene glycol) (PEG) chain for prolonged blood circulation and magnetic resonance imaging (MRI) capability. The PEGylated photosensitizers can self-assemble into micellar nanoparticles for targeted tumor PDT. Furthermore, these nanoparticles can deliver the anticancer drug doxorubicin (DOX) and be used for fluorescence image-guided combination PDT and chemotherapy, effectively suppressing tumor growth in a mouse model. These acid-activatable photosensitizer-incorporated nanoparticles provide a versatile platform for precise PDT and combination breast cancer therapy.
