The article conveys some information:

Early diagnosis of bacterial infection and tracking of treatment effect are of great importance for developing a “”sense-and-treat”” integrated system. Herein, we developed a bacteria-triggered, portable, wearable and colorimetric film-based band-aid (FBA) for closed-loop monitoring and light-controlled therapy of wound infection. FBA with high photothermal conversion efficiency of 52.56% was prepared by wrapping Bi2S3 nanoflowers (BS NFs) loaded with rhodium nanoparticles (Rh NPs) and bromothymol blue (BTB) into LB agar film, integrating bacteria-triggered color change, photothermal/photodynamic therapy (PTT/PDT) synergistic bactericidal therapy and agar-based band aid in one intelligent system. Initially, FBA effectively simulates the pH sensing mechanism, and monitors the occurrence of bacterial infections within 5 min through color changes of Staphylococcus aureus (S. aureus) from blue to yellow and Escherichia coli (E. coli) from yellow to blue. Addnl., the short-term and controlled antibacterial strategy of “”one light dual-mode responses”” (photothermal and photodynamic responses) was implemented with the introduce of near-IR (NIR). Ultimately, the effectiveness of FBA was fully validated in the monitoring and treating of S. aureus-infected mouse wounds. Notably, the designed FBA decisively abandoned off-target side effects maximizing the treatment effect and nakedly tracking therapeutic situation in real time, contributing an effective antibacterial alternative strategy for reducing the use of antibiotics. To the best of our knowledge, such integrated system is still unreported on film-fixed model. In view of the advantages of the low cost and convenience of the simple device, the integrated design is expected to provide a solution for the development of a closed-loop biomedical system combining diagnosis and treatment.

《Gold nanoshells coated 5-aminolevulinic liposomes for photothermal-photodynamic antitumor therapy》 was written by Jiang, Yifei; Liu, Yang; Fang, Siyuan; Ji, Min. SDS of cas: 5471-63-6 And the article was included in Journal of Nanoscience and Nanotechnology in 2020. The article conveys some information:

In this study, a novel antitumor system was designed on the basis of photodynamic therapy and photothermal therapy using gold nanoshells coated 5-aminolevulinic acid (5-ALA) liposomes (GNALs). As a widely used photosensitizer prodrug, 5-aminolevulinic acid (5-ALA)-derived protoporphyrin IX (PpIX) can accumulate to a higher level in tumors than in normal tissues. Protoporphyrin IX (PpIX) initiates a series of cytotoxic reactions after irradiation of target tissue with a measured dose of light with appropriate wavelength, which may be dependent on the generation of reactive oxygen species. Gold nanoshells can strongly absorb NIR lasers at the same time, and can generate hyperthermia to provide photothermic effects. Gold nanoshells coated 5-ALA-Liposomes (GNALs) exhibit a uniform-sized spherical shape of 185.8±0.91 nm, with a zeta potential of 33±1.6 mV. Liposomes with specific sizes ranging from 100 to 200 nm can escape into the tumor interstitial tissue and accumulate preferentially in tumor tissue owing to the EPR effect. In addition, NIR light-excited nanosystems significantly promoted antitumor effects in this study compared to single photodynamic therapy. It was also found that the increased temperature promoted inhibition rate of SKOV3 cells. The novel drug delivery system shows great potential in photothermal-photodynamic antitumor therapy. In the experiment, the researchers used 1,3-Diphenylisobenzofuran(cas: 5471-63-6SDS of cas: 5471-63-6)

1,3-Diphenylisobenzofuran(cas: 5471-63-6) can be 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) can be used as quencher during the photoinactivation of TA-3 mouse mammary carcinoma cells containing hematoporphyrin.SDS of cas: 5471-63-6

Adual-functional nanosysterm is developed by means of Chlorin e6 (Ce6) as photosensitizer and 1,3- Diphenylisobenzofuran (DPBF) as fluorescent singlet oxygen (1O2) probe. Under 660 nmlaser irradation, Ce6 exhibites efficient 1O2 generation, and subsequently the production of 1O2 is assessed by the ratiometric fluorescence of PFO and DPBF under one-photon and two-photon excitation mode. The nanoparticles with excellent biocompatibility can be internalized into Hela cells and applied for tumor treatment. For intracellular PDT, the nanoparticles perform a high phototoxicity, while the PDT proccess can be evaluated in time by monitoring fluorescence signals of DPBF.

Formula: C20H14OIn 2020 ,《Post-synthetically elaborated BODIPY-based porous organic polymers (POPs) for the photochemical detoxification of a sulfur mustard simulant》 appeared in Journal of the American Chemical Society. The author of the article were Atilgan, Ahmet; Cetin, M. Mustafa; Yu, Jierui; Beldjoudi, Yassine; Liu, Jian; Stern, Charlotte L.; Cetin, Furkan M.; Islamoglu, Timur; Farha, Omar K.; Deria, Pravas; Stoddart, J. Fraser; Hupp, Joseph T.. The article conveys some information:

Designing new materials for the effective detoxification of chem. warfare agents (CWAs) is of current interest given the recent use of CWAs. Although halogenated boron-dipyrromethene derivatives (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene or BDP or BODIPY) at the 2 and 6 positions have been extensively explored as efficient photosensitizers for generating singlet oxygen (1O2) in homogeneous media, their utilization in the design of porous organic polymers (POPs) has remained elusive due to the difficulty of controlling polymerization processes through cross-coupling synthesis pathways. Our approach to overcome these difficulties and prepare halogenated BODIPY-based porous organic polymers (X-BDP-POP where X = Br or I) represents an attractive alternative through post-synthesis modification (PSM) of the parent hydrogenated polymer. Upon synthesis of both the parent polymer, H-BDP-POP, and its post-synthetically modified derivatives, Br-BDP-POP and I-BDP-POP, the BET surface areas of all POPs have been measured and found to be 640, 430, and 400 m2·g-1, resp. In addition, the insertion of heavy halogen atoms at the 2 and 6 positions of the BODIPY unit leads to the quenching of fluorescence (both polymer and solution-phase monomer forms) and the enhancement of phosphorescence (particularly for the iodo versions of the polymers and monomers), as a result of efficient intersystem crossing. The heterogeneous photocatalytic activities of both the parent POP and its derivatives for the detoxification of the sulfur mustard simulant, 2-chloroethyl Et sulfide (CEES), have been examined; the results show a significant enhancement in the generation of singlet oxygen (1O2). Both the bromination and iodination of H-BDP-POP served to shorten by 5-fold of the time needed for the selective and catalytic photo-oxidation of CEES to 2-chloroethyl Et sulfoxide (CEESO). The experimental part of the paper was very detailed, including the reaction process of 1,3-Diphenylisobenzofuran(cas: 5471-63-6Formula: C20H14O)

1,3-Diphenylisobenzofuran(cas: 5471-63-6) is a fluorescent dye. 1,3-Diphenylisobenzofuran is the model compound in studies of singlet fission.Formula: C20H14O
