The significant increase in the maximum coverage of LYZ-Au NCs with ionic strength was attributed to the decreasing range of electrostatic interactions between deposited clusters.

This nanoparticle was prepared by encapsulating near-infrared fluorinated triphenylamine-substituted silicon phthalocyanines (TPA-BPAF-SiPc) within mesoporous silica-coated gold nanorods (AuNR@SiO<sub>2</sub>). TPA-BPAF-SiPc@AuNR@SiO<sub>2</sub> functions as a dual-function two-photon probe, facilitating photoactivated lysosome escape and targeting mitochondria. The inherent aggregation-induced emission (AIE) two-photon fluorescence of TPA-BPAF-SiPc is notably bright when encapsulated in AuNR@SiO<sub>2</sub> nanocarriers, a phenomenon not observed in polymer nanocarriers composed of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (DSPE-PEG<sub>2000</sub>) or in THF/water mixtures. Upon irradiation, this nanoparticle autonomously escapes from lysosomes and selectively targets mitochondria, a process can be visually monitored in real-time through the two-photon AIE fluorescence of TPA-BPAF-SiPc. Moreover, upon activation, TPA-BPAF-SiPc@AuNR@SiO<sub>2</sub> produces a substantial quantity of reactive oxygen species (ROS) and induces hyperthermia effects, showcasing its potential for effective photodynamic therapy (PDT) in conjunction with synergistic hyperthermia. Flow cytometry data corroborate the induction of tumor cell death through both necrosis and apoptosis pathways by TPA-BPAF-SiPc@AuNR@SiO<sub>2</sub>. This study underscores the potential of TPA-BPAF-SiPc@AuNR@SiO<sub>2</sub> as a multifunctional probe capable of enabling lysosome escape, mitochondria targeting, and two-photon fluorescence imaging-guided photothermal synergistic photodynamic therapy, specifically tailored for the treatment of breast cancer.</div></div>","PeriodicalId":16159,"journal":{"name":"Journal of Luminescence","volume":"277 ","pages":"Article 120900"},"PeriodicalIF":3.3,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142314454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
