Raspberry-like AgBiS₂@PVP nanoparticles for enhanced sonodynamic and chemodynamic cancer therapy

Abstract

Sonodynamic therapy (SDT) is a non-invasive treatment, which is preferred by many researchers. Ultrasound is applied to the tumor lesions, which are enriched with a sound sensitizer. The activation of...

Calcination-controlled performance optimization of iron–vanadium bimetallic oxide nanoparticles for synergistic tumor therapy

“…In the presence of H 2 O 2 , the oxide can oxidize the substrate TMB to the blue Ox-TMB product with a characteristic absorbance at 652 nm. 30 Therefore, the ability of FVO–Ar NPs to produce ˙OH was detected by UV-vis spectrophotometry using TMB as a color-developing indicator. As shown in Fig.…”

Fiber Identification in Cross Section of Blended Yarn on Back Propagation Neural Network

“…All these problems will result in error or lower accuracy in subsequent identifications. Xing 9 and Xu 10 proposed the concept of a fiber skeleton to remove the narrowest area between the fibers to separate them, but it is difficult to identify the true profile of some fibers.…”

A Colloidal Synthesis Route Towards AgBiS2 Nanocrystals Based on Metal Xanthate Precursors

“…Regarding the synthesis of AgBiS 2 nanomaterials, so far several studies report on the synthesis and characterization of AgBiS 2 crystals via microwave-assisted and solvothermal processes in solvents such as water, ethylene and propylene glycol. [15][16][17] Common precursors for these syntheses are metal salts, such as nitrates, acetates and chlorides, and sulfur sources, like thiourea, [18] thiosemicarbazide, [17] carbon disulfide [6] as well as the biomolecule L-cystine. [19][20][21] Microsphere shaped AgBiS 2 particles were also prepared through similar processes with the help of polyethylene glycol (PEG) [22,23] and hypocrellin [24] as templating agents, which were subsequently used as catalysts for the polymerization of alkylsilanes.…”
