Electrocatalytic oxidation of acetylsalicylic acid at multiwalled carbon nanotube-alumina-coated silica nanocomposite modified glassy carbon electrodes

Electrochemical sensor for the simultaneous determination of caffeine and aspirin in human urine samples

“…Aspirin is clinically employed for analgesic and antipyretic effects and some amount of unmetabolized drug usually excretes in patient urine [6]. Hence, it is considered worthwhile to determine the concentration of aspirin in urine sample of heart patient undergoing treatment with Ecospirin-150.…”

“…ASA also known as aspirin, inhibits the enzyme cyclooxygenase with consecutive reduction of prostaglandin and thromboxanes [4]. ASA is generally used to treat different types of pain, such as, headache, muscle aches, arthritis, menstrual cramps, backache and sinus infection and is also effective in Alzheimer' disease and cardiovascular diseases [5][6][7][8]. 1,3,7-trimethylxanthine, also known as caffeine (CAF), is an alkaloid having the basic properties of an organic amine found in food products such as coffee, tea, yerbamate, guarana berries, cola nuts and cacao beans [9].…”

“…These methods are usually very expensive; more complicated and long time is required for derivatization, extraction and purification of the species prior to their determination using these methods [19][20][21][22][23]. Electrochemical methods including voltammetric techniques have also been developed for the individual and simultaneous determination of aspirin and caffeine using modified electrodes [5,6,9]. These reports need extra time consuming modification process that involves various steps in incorporation of the modifier to the substrate [5,6] determination of caffeine since it oxidizes at high potential using conventional electrodes, hence, there can be a possibility of overlapping with the potential of discharged electrolytic solution leading to poorly reproducible results [10].…”

Pharmaceutical electrochemistry: The electrochemical detection of aspirin utilising screen printed graphene electrodes as sensors platforms

“…For instance Srivastava et al [11] used surfactant-modified multiwalled carbon nanotube paste electrode for the determination of ASA in pharmaceutical formulations, urine and blood samples by voltammetry. Tsai et al [12] investigated the electrocatalytic oxidation of acetylsalicylic acid at multiwalled carbon nanotube-alumina-coated silica nanocomposite modified glassy carbon electrodes. Lu et al [13] reported an electrochemical sensor based on AuNPs modified molecularly imprinted polymer film for the detection of ASA.…”

Fabrication, characterization and analytical performance of the hydroxylamine sensor based on an oracet blue multi-walled carbon nanotubes film deposited on an electrode surface

“…[13][14][15][16][17] Indeed, these compounds are used in an electrode structure so as to promote the rate of electron transfer reactions. The electrocatalytic activity of important chemical and biochemical species, such as hydrazine, 18 epinephrine, 19 amino acids, 20 oxygen, 21 paracetamol, 22 hemoglobin, 23 acetylsalicylic acid, 24 rutin, 25 cholesterol, 26 NADH and hydrogen peroxide, 27 ascorbic acid, 28 uric acid, 29 nitric oxide, 30 glucose, 31 and hydroxylamine, 10,14 have been investigated at the surface of different electrodes modified with CNTs.…”
