“…The reported spectrofluorimetric method 16 was based on measuring the fluorescence quenching of quinine sulphate by chloride ions which were produced from oxidation reaction of PAR with potassium chlorate in acidic medium. Other reported spectrofluorimetric method for the determination of paracetamol via oxidation is presented using different oxidizing reagents as sodium hypochlorite, 18 cerium( iv ) 19,20 and N -bromosuccinimide (NBS) to produce a highly fluorescent product.…”

Paracetamol is a non-steroidal, anti-inflammatory drug widely used in pharmaceutical applications for its sturdy, antipyretic and analgesic action. However, an overdose of paracetamol can cause fulminant hepatic necrosis and other toxic effects. Thus, the development of advantageous analytical tools to detect and determine paracetamol is required. Due to simplicity, higher sensitivity and selectivity as well as costefficiency, electrochemical sensors were fully investigated in last decades. This review describes the advancements made in the development of electrochemical sensors for the paracetamol detection and quantification in pharmaceutical and biological samples. The progress made in electrochemical sensors for the selective detection of paracetamol in the last 10 years was examined, with a special focus on highly innovative features introduced by nanotechnology. As the literature is rather extensive, we tried to simplify this work by summarizing and grouping electrochemical sensors according to the by which manner their substrates were chemically modified and the analytical performances obtained.

“…The deposition electrolyte should not decompose at the selected deposition potentials and should show electrical conductivities 14 . Polyaniline (PANI) has been synthesized commonly from and cycled in acidic aqueous media 15 . Non‐aqueous media (ionic liquid 16 and organic electrolytes 17 ) have been used to polymerize aniline because organic and ionic liquid electrolytes can offer wide potential windows (up to 3.5 V) with the cycling electrolytes used 18 .…”

A sticky surface of a tape was adhered to a graphite surface and then the tape was peeled off. The insulator tape was coated with thin graphite and became conductive in order to use flexible tape as a current collector. Aniline was electrodeposited onto a flexible tape substrate having graphite layer by electrochemical polymerization method from an aqueous (H 2 SO 4 solution containing aniline monomers) and non-aqueous media (a deep eutectic solvent containing aniline). The prepared polymeric electrodes were characterized by Fourier transform infrared spectroscopy, Raman, thermogravimetric analysis and scanning electron microscopy techniques. The electrochemical properties of coated and uncoated electrodes were also examined by cyclic voltammetry and galvanostatic charge discharge techniques. The polyaniline (PANI) coated tape can be used as a flexible electrode in supercapacitor applications because PANI coated electrodes are highly electroactive in Na 2 SO 4 electrolyte. After 3000 cycles, the capacitance retention of PANI film electrodeposited from Ethaline bath was 90%, while the areal capacitance of PANI film obtained from acidic medium reaches 50% after 500 cycles. As PANI electrode is stable in an ionic liquid for long cycling, Ethaline ionic liquid can be used as electrolyte for PANI based supercapacitor electrode. PANI coated graphite on tape, which is prepared in an easy and inexpensive way is a promising flexible material for high performance supercapacitors.
