Graphene nanoplatelets like structures formed on ionic liquid modified carbon-ceramic electrode: As a sensing platform for simultaneous determination of dopamine and acetaminophen

“…With the aim of improving the selectivity, it is essential to separate the signals from each other. Therefore, various modified electrodes such as polyDAN-RB4/GC [2], Fe3O4@Au\ \S\ \Fc/GS-Chitosan/GCE [3], Ppyox/AZ/Au [4], SWCNT/ CCE [5], MWCNT/GCE [6], Pyrolytic carbon (PyC) films [7], Gr-FEPA-CS/GCE [8], and ERGO/ZrO 2 [9] were applied for simultaneous determination of them.…”

Nitrogen-doped pyrolytic carbon films as highly electrochemically active electrodes

“…This oxygen plasma treated PyC was shown to be suitable as the electrode material in simultaneous electrochemical sensing of dopamine and paracetamol. 30 Herein we present work on nitrogenation of PyC films via exposure to a downstream ammonia-hydrogen (NH 3 -H 2 ) plasma mixture. The NH 3 radicals reacted with the carbon films to create nitrogen functional groups on the surface of the PyC.…”

One-step electrochemical preparation of a reduced graphene oxide/poly(sulfosalicylic acid) nanocomposite film for detection of acetaminophen and its application in human urine and serum studies

“…Acetaminophen (paracetamol or N-acetyl-p-aminophenol) (AC), an acetyl aniline drug, is an effective substitute for aspirin and extensively used as antipyretic and analgesic drug 1 . Up to now, numerous electrochemical materials have been developed for the determination of AC, such as single-walled carbon nanotubegraphene nanosheet hybrid films 10 , multi-walled carbon nanotubes/poly(glycine) composite 11 , poly(new coccine) film 12 , poly (3, 4-ethylenedioxythiophene) 13 , thin pyrolytic carbon films 14 , However, the overdoses of AC may cause adverse effects in human body, including the digestive, urinary, blood, and respiratory systems 3,4 .…”
