The ever-increasing threats of multidrug-resistant bacteria and their biofilm-associated infections have bred a desperate demand for alternative remedies to combat them. Near-infrared (NIR)-absorbing photothermal agent (PTAs)-mediated therapy (PTT) is particularly attractive biofilm ablation thanks its superiorities noninvasive intervention, satisfactory antibacterial efficiency, less likelihood develop resistance. Herein, three butterfly-shaped aggregation-induced emission luminogens (AIEgens) with balanced nonradiative decay (for conducting PTT) radiative supplying fluorescence in the NIR-II optical window) are rationally designed imaging-assisted obliteration bacterial biofilms. After being encapsulated into cationic liposomes, AIEgens-fabricated nanoparticles can eradicate wide spectrum biofilms formed by Gram-positive (methicillin-resistant Staphylococcus aureus Enterococcus faecalis) Gram-negative (Escherichia coli Pseudomonas aeruginosa) upon an 808 nm laser irradiation. In vivo experiments firmly demonstrate that AIE liposomes excellent biocompatibility perform well both P. aeruginosa biofilm-induced keratitis mouse model MSRA skin infection model.

Multimodal therapy is attracting increasing attention to improve tumor treatment efficacy, but generally requires various complicated ingredients combined within one theranostic system achieve multiple functions. Herein, a multifunctional nanoplatform based on single aggregation-induced-emission luminogen (AIEgen), DDTB, designed integrate near-infrared (NIR) fluorescence, photothermal, photodynamic, and immunological effects. Intravenously injected AIEgen-based nanoparticles can efficiently accumulate in tumors with NIR fluorescence provide preoperative diagnosis. Most of the are excised under intraoperative navigation, whereafter, some microscopic residual completely ablated by photodynamic photothermal therapies for maximally killing cells tissues. Up 90% survival rate be achieved this synergistic image-guided surgery therapies. Importantly, nanoparticles-mediated photothermal/photodynamic plus programmed death-ligand 1 antibody significantly induce elimination enhancing effect immunotherapy. This strategy basis AIEgen improves cancer mice maximized therapeutic outcomes, holds great promise clinical treatment.

Abstract Golgi apparatus (GA) oxidative stress induced by in situ reactive oxygen species (ROS) could severely damage the morphology and function of GA, which may open up an avenue for effective photodynamic therapy (PDT). However, due to lack design strategy, photosensitizers (PSs) with specific GA targeting ability are high demand yet quite challenging. Herein, we report aggregation-induced emission luminogen (AIEgen) based PS (TPE-PyT-CPS) that can effectively target via caveolin/raft mediated endocytosis a Pearson correlation coefficient 0.98. Additionally, introduction pyrene into TPE-PyT-CPS reduce energy gap between lowest singlet state (S 1 ) triplet (T (Δ E ST exhibits enhanced generation capability. fragmentation cleavage proteins (p115/GM130) observed upon light irradiation. Meanwhile, apoptotic pathway is activated through crosstalk mitochondria HeLa cells. More importantly, TPE-T-CPS show better PDT effect than its non-GA-targeting counterpart TPE-PyT-PS, even though they possess very close ROS rate.
