Summary: Metastasis is the main cause of cancer-related deaths, and early detection of tumor metastasis is crucial for better prognoses. In this study, a phosphorescence imaging method using organic nanoparticles was developed to detect microenvironmental changes associated with early tumor metastasis, allowing for early detection before the formation of secondary tumors. This method demonstrated superior sensitivity and convenience compared to other imaging methods, detecting metastases as early as day 3 in experimental models.

Summary: In this study, we report a rational design of triplet sensitizers to achieve high-efficiency red afterglow emission at room temperature. By synthesizing sensitizer and acceptor molecules with different conjugated substituents, we found that the long conjugated substituent greatly enhanced the phosphorescence resonance energy transfer (PRET) from the sensitizer to the acceptor, resulting in improved yield of red afterglow emission at room temperature.

Summary: In this study, improved resolution of bright afterglow emission was achieved by performing photoinduced triplet depletion. Triplet depletion was achieved by charge separation through photoionization from a triplet state caused by depletion and subsequent rapid singlet formation. A higher-resolution afterglow image with an improvement of 25% was obtained by simultaneous focusing of a donut-shaped depletion beam and an excitation beam.

Summary: Magnetothermal therapy (MHT) is a promising non-/minimal invasive and efficient approach for tumor treatment. However, the development of small MHT agents (< 50 nm) with excellent magnetothermal conversion performance and high tumor enrichment remains challenging. In this study, a macrophage-mediated delivery system was designed for enhanced magnetic resonance imaging (MRI) and MHT of solid tumors using small Fe@Fe3O4-DHCA nanoparticles. The aggregation of Fe@Fe3O4-DHCA nanoparticles in macrophages resulted in enhanced MRI and magnetothermal performance in vitro. Moreover, the in vivo MHT effect of macrophages loaded with Fe@Fe3O4-DHCA was superior to that of Fe@Fe3O4-DHCA alone, attributed to the tumor-targeting capability of macrophages. This macrophage-mediated delivery system presents a new strategy for enhanced MHT based on Fe@Fe3O4-DHCA nanoparticles, with great potential for clinical tumor therapy.

Summary: Ultrasound-triggered sonodynamic therapy (SDT) has gained significant attention as a non-invasive and deep tissue penetration alternative for cancer treatment. However, the efficacy of SDT alone is limited by the hypoxic nature of solid tumors. Therefore, this study develops an intelligent theranostic nanoplatform that combines SDT and nitric oxide (NO) therapy to enhance cancer treatment.

Summary: Endogenous activated nanomedicines have significant potential in cancer therapy by improving therapeutic efficacy and reducing side effects. In this study, a novel nanomedicine (CuHCF) was developed based on a mixed-metal Prussian blue analogue, which could respond to endogenous labile iron pool achieving enhanced chemodynamic therapy and in situ NIR-II photothermal therapy of the tumor. The CuHCF showed low Fenton catalytic activity but significantly amplified reactive oxidative species generation when exposed to over-expressed Fe2+ in the tumor region via redox cycles. Furthermore, CuHCF exhibited enhanced near-infrared absorption and enabled in situ hyperthermia under NIR-II irradiation. Synergistic therapy of CDT/PTT was achieved by combining CuHCF with the ferroptosis inducer erastin.

Summary: A hollow mesoporous manganese dioxide-based multifunctional nanoplatform was developed for synergistic cancer treatment, which loaded a histone deacetylase inhibitor AFIPB in its hollow cavity and covalently decorated a ruthenium nitrosyl donor and a folic acid targeting group on its covered polydopamine layer. The nanoplatform exhibited tumor microenvironment-responsive properties and could deplete glutathione to disrupt the antioxidant defense system and deliver drugs on demand. Furthermore, it could generate highly toxic hydroxyl radicals through the catalysis of released Mn2+ and produce controlled nitric oxide delivery and significant photothermal effect under 808 nm light irradiation, resulting in high mortality of cancer cells.

Summary: We developed a nanoplatform for combined chemotherapy and enhanced chemodynamic therapy by self-assembling a water-soluble and amphipathic ferrous metallacage (FM), hydrophilic copolymer (PEG2000-COOH), and oxaliplatin (OXA). The FM acted as a catalyst for the Fenton reaction and potential agent for chemodynamic therapy. OXA not only served as an anti-tumor drug but also activated intracellular enzymes to enhance the chemodynamic therapy effect. In vitro and in vivo experiments demonstrated that FM@OXA-PEG showed minimal toxicity to normal cells, while effectively killing tumor cells and inhibiting tumor growth.

Summary: This article introduces a clever combination of nano-enzymes and therapeutic drugs that can promote the production of reactive oxygen species (ROS) in cancer cells, enhancing the therapeutic efficacy of nanomedicines on malignant tumors. By loading the specific drug onto PEGylated Ce-doped hollow mesoporous silica nanoparticles, a smart nanoplatform is constructed to improve tumor therapy efficiency. The carrier showed multi-enzyme activities, with Ce3+ ions converting endogenous H2O2 into highly toxic OH for chemodynamic therapy and Ce4+ ions exhibiting catalase-like activity to reduce tumor hypoxia and glutathione (GSH) peroxidase-mimicking properties to effectively deplete GSH in tumor cells. Moreover, the loaded drug disrupts mitochondrial functions, causing the accumulation of superoxide anions (O-2(-)) and H2O2 within tumor cells. By combining the advantages of the carrier and the drug, the prepared nanoplatform can efficiently induce cancer cell death and inhibit tumor growth through significantly enhanced ROS production. Therefore, this positive combination therapy strategy has a promising application prospect for enhancing antitumor efficacy.

Summary: In this study, a pH- and glutathione (GSH)-responsive T-1-T-2 dual-mode contrast agent, Fe3O4@ZIF-8-Zn-Mn nanoparticles (NPs), was constructed to improve the sensitivity and accuracy of magnetic resonance imaging (MRI). The NPs showed good stability and weak T-1-T-2 dual-mode MRI contrast effect under neutral conditions, but could be disassembled and release Fe3O4 NPs and paramagnetic Mn2+ ions under acidic environment (pH = 6.5-5.5) and in the presence of GSH (0-4 mM), resulting in enhanced T-1 and T-2 imaging performances. In vivo MRI experiments demonstrated the potential of Fe3O4@ZIF-8-Zn-Mn NPs as a tumor microenvironment-responsive T-1-T-2 dual-mode contrast agent for sensitive tumor imaging.
