ABSTRACT Imaging‐guided phototherapy holds promise for precision cancer treatment. However, most photosensitizers have only a singular modality of photodynamic therapy (PDT) or photothermal (PTT), which make their therapeutic efficacy severely limited by the hypoxic and complex tumor microenvironment (TME). In this article, we provide smart platform design (BOD‐D) based on visualized light‐triggered phototherapeutic switch transforming from near‐infrared (NIR)‐I imaging‐guided PDT to activatable NIR‐II‐guided PTT while releasing nitric oxide (NO) gas (GT). BOD‐D releases native NIR one‐region fluorescence signals in tumors, is used direct robust killing. As administered, decreasing oxygen content TME becomes progressively insufficient maintain its excellent cell‐killing effect. Subsequently, light triggers dissociation NO BOD‐D, activating agent BOD‐T that emits NIR‐II fluorescence, subsequent PTT. Notably, not light‐mediated mechanism can be switched NIR‐I‐guided PTT, but also released during process will GT sensitize above Our study contributes intelligent cascade photoablation.

Herein, we develop photodynamic therapy (PDT)-accelerated supramolecular nanomaterials based on α-cyclodextrin (α-CD), red-emitting AIEgens (namely, TPE-Py) and a hypoxia-activated paclitaxel-based prodrug PTX-NB), which surpasses hypoxia limitations enhances the efficiency of chemotherapeutic release in melanoma. The cationic AIEgen functions as guest molecule, capable forming complex with α-CD 1:1 binding ratio, showing an increased fluorescence intensity. Interestingly, such accelerates type II ROS generation through consumption intracellular oxygen to result severe hypoxic microenvironment facilitate hypoxia-responsive release. Then, TPE-Py⊂α-CD PTX-NB are coassembled into nanoparticles aid DSPE-PEG2000 for anticancer investigation. Benefiting from excellent PDT property self-accelerated prodrug, these successfully used bioimaging antitumor treatment vitro vivo good biosafety. This strategy helps enhance precision tumor treatment.

Abstract Organic agents possessing NIR‐II and photoacoustic duplex imaging capabilities, coupled with high‐efficiency photothermal conversion, offer significant potential for noninvasive precise phototheranostics of glioblastoma, which is further augmented when these can concurrently exhibit tumor targeting blood–brain barrier (BBB) permeability. This study reports a series finely tunable molecular luminophores based on the aza‐BODIPY scaffold, featuring unique twisted rotatable structures. They are constructed to folate‐decorated polymeric nanoparticles, exhibiting remarkable NIR‐II/photoacoustic performance superior conversion efficiency (49.7%). Folate modification enables BBB permeability through receptor‐mediated transcytosis, allowing efficient phototherapy in 4T1‐/glioblastoma‐bearing mice after single intravenous injection irradiation. presents rational engineering approach versatile structural scaffold designing emitters tailored photophysical properties desirable phototherapeutic efficacy, thereby offering novel perspectives development advanced depth probes brain therapeutics.

Abstract The treatment of ammonia nitrogen wastewater (ANW) has garnered significant attention due to the ecology, and even biology is under increasing threat from over discharge ANW. Conventional ANW methods often encounter challenges such as complex processes, high costs secondary pollution. Considerable progress been made in employing solar-induced evaporators for treatment. However, there remain notable barriers transitioning fundamental research practical applications, including insufficient evaporation rates inadequate resistance biofouling. Herein, we propose a novel evaporator, which comprises bio-enzyme-treated wood aerogel that serves water pumping storage layer, cost-effective multi-walled carbon nanotubes coated hydrophobic/hydrophilic fibrous nonwoven mat functioning photothermal aggregation-induced emission (AIE) molecules incorporated anti-biofouling agent. resultant bioinspired evaporator demonstrates rate 12.83 kg m −2 h −1 when treating simulated containing 30 wt% NH 4 Cl 1.0 sun illumination. AIE-doped exhibits remarkable photodynamic antibacterial activity against mildew bacteria, ensuring outstanding biofouling extended periods When enhanced by natural wind irradiation, achieves an impressive exceeding 20 . This advancement represents promising viable approach effective removal wastewater.
