Summary: A supramolecular strategy was presented to build a water-stable, nonphotobleaching, and NIR-absorbing nano-PTA (J-NP) from J-aggregation of halogenated BODIPY dyes for efficient in vivo photothermal therapy. The remodeled J-NP significantly improved cellular uptake efficiency and exhibited efficient antitumor photothermal activities in vivo. This work not only establishes a supramolecular platform for high photothermal performance PTAs but also enables appealing optical functions derived from J-aggregation to be applied in vivo.

Summary: Photothermal therapy has limitations in treating deep tissues due to the limited penetration depth of light. To overcome this, the strategy of endovascular photothermal precision embolization (EPPE) is introduced, which uses an endovascular optical fiber to induce local embolization and block the blood supply of the whole tumor. EPPE uses a highly efficient and biocompatible photothermal agent, which effectively kills cells both in 2D and 3D models. The feasibility of EPPE is verified in ex vivo liver models and in vivo rat liver models.

Summary: Photothermal therapy has been established as an effective non-invasive treatment for cancer metastatic lymph nodes, but the monitoring and reporting of treatment progress still need to be explored. In this study, pegylated gold nanorods were delivered via the lymphatic route and combined with laser irradiation, resulting in a time-dependent reduction in tumour activity and statistically significant treatment response even after conclusion. This non-invasive technique could offer more insights into tumour therapy dynamics through lymphatic administration in preclinical studies.

Summary: Phototherapy, including photothermal therapy (PTT) and photodynamic therapy (PDT), is widely used for cancer treatment, but conventional PTT/PDT lack disease recognition ability, resulting in limited therapeutic effects. Integrating fluorescence imaging with PTT/PDT can reveal tumor locations in real-time, enabling early diagnosis and precision treatment. The use of NIR-II fluorescence imaging with PTT/PDT can significantly improve tumor theranostics accuracy and minimize damage to normal tissues.

Summary: Modifying the phen ligand can significantly reduce the nucleolytic activity of Cu-II complexes, but those with fluorinated substituents show excellent DNA cleavage activity. The nucleolytic activity of these complexes correlates well with their half-wave potentials. Cancer cell studies indicate cytotoxic effects of complexes with fluorinated ligands, while they are less toxic to healthy cells.

Summary: Advancements in nanogel applications require precise control over their size, structure, and functionalization. In this work, a post-synthesis reaction strategy was developed to modify the structure and functionalization of thermoresponsive nanogels. The incorporation of a cleavable crosslinker allows control over the crosslinking degree and architecture of the nanogels, and introduces alpha-oxoaldehydes for subsequent bio-conjugation. This strategy provides a valuable tool for fine-tuning drug delivery nanodevices in a post-synthetic step.
