General description

1,3-Diphenylisobenzofuran is a fluorescent dye[1].1,3-Diphenylisobenzofuran is the model compound in studies of singlet fission[2].

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]. 1,3-Diphenylisobenzofuran(DPBF) was used as quencher during the photoinactivation of TA-3 mouse mammary carcinoma cells containing hematoporphyrin[3]. 1,3-Diphenylisobenzofuran(DPBF) was used to study the single crystal molecular structure and solution photophysical properties of DPBF[2].

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

Questions

1–2 of 2 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
