Effect of colloidal β‐cyclodextrins–Fe3O4 magnetic nanoparticles on the chemiluminescence enhancement of luminol–Ag(III) complex for rapid and sensitive determination of cysteine in human serum

“…1a) (13). Additionally, nanomaterials have recently been a rapidly growing field involving the use of nanoparticles as catalysts for a variety of organic and inorganic reactions (14,15). Recently, CL studies have been extended to nanoparticles systems, which can participate in CL reactions as a reductant, catalyst and luminophor.…”

Metal(II) Formates (M = Fe, Co, Ni, and Cu) Stabilized by Tetramethylethylenediamine (tmeda): Convenient Molecular Precursors for the Synthesis of Supported Nanoparticles

“…Metal supported nanoparticles are the most common heterogeneous catalysts used in industry. [1][2][3] They are used in a broad range of applications, such as the methane conversion processes, [4 -9] biomass transformation, [10,11] or fine chemical synthesis. [12,13] Numerous parameters influence the performances of these catalysts, such as the type of support, [14,15] the metal nanoparticles size, [16,17] and their interaction with the support.…”

Formation of silver nanoparticles induced by ultrasonically treated sodium dodecyl benzene sulphonate

“…The reduction of metal ions by an ultrasonic radiation method has been used to a smaller extent to prepare surfactant or polymer‐stabilised metal NPs [14], such as silver [15, 16], gold [17, 18] and platinum [19, 20]. At the same time, ultrasonic wave radiation methods are able to create narrow metal particle sizes [21]. Nagata et al .…”

“…[23] reported that fine particles of palladium are readily produced under sonication conditions. Gedanken reported on the preparation of Ni, Cu, Pd or Fe particles by the same procedure, and that a smaller size and greater surface area than those reported can also be obtained [21]. At present, there are few studies that attempt to generate the desired AgNPs by sonochemical radiation; both reducing agents and stabilising agents are needed during ultrasonic radiation and existing research needs to be improved further [24, 25].…”
