Description générale

1,3-Diphenylisobenzofuran is a fluorescent dye.1,3-Diphenylisobenzofuran is the model compound in studies of singlet fission.

Application

1,3-Diphenylisobenzofuran(DPBF) was used as a fluorescent probe for detection of superoxide anion radical (O2) inside the membrane lipid layer by DPBF fluorescence quenching method. 1,3-Diphenylisobenzofuran(DPBF) was used as quencher during the photoinactivation of TA-3 mouse mammary carcinoma cells containing hematoporphyrin. 1,3-Diphenylisobenzofuran(DPBF) was used to study the single crystal molecular structure and solution photophysical properties of DPBF.

Utilization of a fluorescence dye, 1,3-diphenylisobenzofuran (DPBF) as a detector of superoxide anion radical (O2*-) was examined. The fluorescence intensity of DPBF incorporated in phospholipid liposomes consisting of phosphatidylcholine (PC) and phosphatidylserine (PS) is effectively quenched by incubation with xanthine/xanthine

Significant efforts are currently being funneled into the improvement of therapeutic outcomes in cancer by designing hybrid nanomaterials that synergistically combine chemotherapeutic abilities and near-infrared (NIR) light-activated photothermal (PTT) and photodynamic (PDT) activity. Herein, a nanotherapeutic platform is specifically designed

A major challenge in photodynamic therapy (PDT) is the development of new tumor-targeting photosensitizers. The tumor-specific activation is considered to be an effective strategy for designing these photosensitizers. Herein, we describe a novel tumor-pH-responsive supramolecular photosensitizer, LDH-ZnPcS

In this work, a triple-stimuli (GSH, pH and light irradiation) responsive system were designed based on CeO2 nanoparticles (CeO2 NPs) coated doxorubicin (DOX) and photosensitizer hematoporphyrin (HP) dual-loaded mesoporous silica nanoparticles (MSN). Upon entering into cancer cells, both high concentration

Photodynamic therapy (PDT) utilizing light-induced singlet oxygen has achieved attractive results in anticancer fields; however, its development is hindered by limited light penetration depth, skin phototoxicity, tumor hypoxia, and PDT-induced hypoxia. Inspired by our previous research work and the limitations
