Abstract The present study reported the preparation of BiVO 4 by co-precipitation method. as-prepared photocatalyst were deposited on rGO sheets to form /rGO via hydrothermal crystalline structure, morphological, optical properties, and surface properties synthesized pure compared composite studied using X-ray diffraction (XRD), scanning electronmicroscopy (SEM), photoluminescence (PL) spectrophotoscopy, UV–vis spectrophotometer with an integrating sphere, N 2 adsorption-desorption isotherm...
WO3/CeO2 heterostructured nanocomposites containing different WO3 ratios (0.1, 0.3, 0.5, and 1.0 wt %) were synthesized by a precipitation method. The coupling of CeO2 with high specific surface area noticeably enhanced the photocatalytic activity indigo carmine (IC) degradation under visible-light irradiation. rate constants (k) 0.5 % reached 4 5 times higher than those WO3, respectively. Regarding experimental results, X-ray diffraction (XRD) patterns spherical nanoparticles rod-shaped...
We developed a membraneless-microfluidic biofuel cell (MBFC) for the quantification of ethanol. The system employs anolyte and catholyte solutions, each containing biocatalyst redox mediator. laminar flow conditions in microfluidic chip minimize mixing between obviate need membrane to separate them. When ethanol is added anolyte, alcohol dehydrogenase (ADH) catalyzes its oxidation acetaldehyde, releasing electrons anode. On cathode, are transferred horseradish peroxidase (HRP), which reduces...
We developed a pH dependent amino heptamethine cyanine based theranostic probe (I
Biofuel cells allow for constructing sensors that leverage the specificity of enzymes without need an external power source. In this work, we design a self-powered glucose sensor based on biofuel cell. The redox dehydrogenase (NAD-GDH), oxidase (GOx), and horseradish peroxidase (HRP) were immobilized as biocatalysts electrodes, which previously engineered using carbon nanostructures, including multi-wall nanotubes (MWCNTs) reduced graphene oxide (rGO). Additional polymers also introduced to...
The intramolecular fluorocyclization of unsaturated carbamates proceeds <italic>via</italic> a cyclization/1,2-(hetero)aryl migration/fluorination cascade involving an unusual radical process, and provides straightforward access to (radio)fluorinated oxazolidin-2-ones, oxazolidine-2,4-diones 1,3-oxazinan-2-ones.
In this work, we synthesize a quinoline-based heptamethine cyanine, QuCy7, with sulfonate groups to enhance water solubility. This dye demonstrates exceptional near-infrared absorption beyond 750 nm, accompanied by photothermal properties but low photostability. Encapsulating QyCy7 polyethylene glycol form nanopolymer, QuCy7@mPEG NPs, addresses the issue of its photoinstability. TEM showed that NPs possess spherical morphology, featuring core-shell structure size around 120 nm in diameter....
The reduction of unfriendly 4-nitrophenol to make it unimpactful with the environment (4-aminophenol) was carried out using metastable form copper ferrite (CuFe5O8) synthesized by co-precipitation metal nitrate salts, an efficient method inexpensive and abundant starting materials. samples were obtained calcination at various temperatures ranging from 600 °C 900 °C. material characterizations, including X-ray diffraction, N2 adsorption/desorption, scanning electron microscope, absorption...
In this report, we show that [18F]-zwitterionic aryltrifluoroborates with ortho-phosphonium groups are: (i) easily accessible via direct 18F–19F isotopic exchange reactions in aqueous solutions; and (ii) efficiently stabilized vivo against fluoride ion dissociation.
We designed and optimized a glucose biosensor system based on screen-printed electrode modified with the NAD-GDH enzyme. To enhance electroactive surface area improve electron transfer efficiency, we introduced graphene oxide (GO) ferrocene-modified linear poly(ethylenimine) (LPEI-Fc) onto surface. This strategic modification exploits electrostatic interaction between oxide, which possesses negative charge, LPEI-Fc, is positively charged. results in increased catalytic current during...
In this work, four thymol-based benzoxazines were synthesized using primary amines with different chain lengths, namely methylamine, ethylamine, 1-propylamine, and 1-butylamine, which are then named T-m, T-e, T-p, T-b, respectively. The optical properties of the examined via photoluminescent study their solutions in acetone. results show that all prepared emitted blue light maximum wavelengths from 425 to 450 nm when irradiated by excitation 275 315 nm. found be polymerization is triggered...
The radiofluorination of N-heterocyclic carbene (NHC) boron trifluoride adducts affords novel [ 18 F]-positron emission tomography probes which resist hydrolytic fluoride release.
Recently, we demonstrated the potential of a [(18) F]-trimethylammonium BODIPY dye for cardiac imaging. This is first example use F]-ammonium positron emission tomography (PET) myocardial perfusion imaging (MPI). In this report, extend our study to other ammonium dyes with different nitrogen substituents. These novel were successfully prepared and radiolabeled by SnCl4 -assisted (18) F-(19) F isotopic exchange method. The microPET results biodistribution data reveal that substituent changes...
Glycoconjugate aza-BODIPY dyes (<bold>AZB-Glc</bold> and <bold>AZB-Glc-I</bold>) exhibit increased tumor uptake owing to the Warburg effect enhanced photodynamic therapy (PDT).
A novel pyridylhydrazone-tethered BODIPY (BODIPY-PH) was synthesized, fully characterized via nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopic (FTIR), and single-crystal X-ray diffraction (SC-XRD) techniques, developed for the selective detection of Fe3+ through fluorescent enhancement process.

Photothermal therapy is a promising treatment modality in the realm of cancer therapy. nanomaterials that absorb and emit near-infrared range (750-900 nm) have drawn lot attention recently because deep penetration NIR light biological tissue. Most nanomaterials, however, are produced by encapsulating or altering surface nanoplatform, which has limited loading capacity long-term storage. Herein, we developed stable polymer conjugated with aza-BODIPY self-assembled to form nanoparticles (
