A new generation electrochemical sensor based on Graphene nanosheets/Gold nanoparticles/Nafion nanocomposite for determination of Silodosin

Electrochemical sensor for Isoniazid based on the glassy carbon electrode modified with reduced graphene oxide–Au nanomaterials

“…By combination of graphene with metal nanoparticles, a novel class of carbon-based functional nanomaterials has been developed to optimize the electrical, optical, biological, and catalyst properties because graphene possesses large interfacial surface area [32,[36][37][38][39][40][41].…”

A new electrochemical sensor based on a nitrogen-doped graphene/CuCo2O4nanocomposite for simultaneous determination of dopamine, melatonin and tryptophan

“…[1][2][3][4][5] As a two-dimensional single-atom-thick carbon network, graphene (G) has been a research focus due to its unique structure and physiochemical properties. 11,12 The catalytic activity of the metal-NPs upon the electron transfer process paves the way for the production of metal-NPs/G composite based electrochemical sensors. [6][7][8][9][10] The production of G by the reduction of G oxide (GO) in chemical way produce hydroxyl (-OH) and carboxylate (-COOH) groups in the structure.…”

“…6 G has exhibited specic characteristics including extremely electric conductivity, large specic surface area, unusual electronic structure, and upstanding thermal conductivity. 12,13 However, G sheets tend to irreversible agglomeration and re-stacking because of their strong van der Waals interactions and p-p stacking, 14 which causes some loss of performance for metal-NPs/G nanocomposites in the detection process. These active functional groups enable the G structure to interact with metal NPs.…”

An effective and sensitive stability-indicating chromatographic approach based on HPLC for silodosin assay

“…The literature revealed that various analytical methods have been reported to determine the SIL in pharmaceutical or clinical samples including UV spectrophotometry (Jahan and Malipatil 2014b), spectrofluorimetry (Bhamre and Rajput 2014), high-performance liquid chromatography (HPLC) (Jahan and Malipatil 2014a ;Aneesh and Rajasekaran 2012;Vali et al 2012), high-performance thin-layer chromatography (Sayana et al 2012), ultra high-performance liquid chromatography (UHPLC) (Shaik et al 2014;Prasad et al 2012) and liquid chromatographytandem mass spectrometry (LC-MS/MS) (Zhao et al 2009) and electrochemicalsensing (Er et al 2015) methods. Recently, the authors have attached great importance develop the sensitive and reliable analytical methods for determination of biological and drug molecules at nano-molar levels.…”
