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.

“…Moreover, it is a very effective medication commonly used against pain or for reduction of fever in adults and children. Currently, it is one of the most widely employed drugs in the world being used without a prescription and without knowledge of the adequate dosage, toxicity and side-effects [28][29][30]. According to literature, the use in excess of AC leads to hepatotoxicity, nephrotoxicity and pancreatic diseases [31,32].…”

“…In the literature, there are reports various methods AC determination using different analytical techniques such as spectrophotometry [36][37][38] and chromatography [39,40]. Electroanalytical methods are also reported utilizing different unmodified and modified carbon electrodes [28,30,[41][42][43][44][45][46][47][48][49][50][51][52][53][54][55]. Additionally, two works has been published in the literature involving the use of PEC sensors for AC determination.…”

A new and simple photoelectrochemical (PEC) sensor using a glassy carbon electrode (GCE) modified with bismuth vanadate (BiVO4) nanoparticles and dihexadecyl phosphate (DHP) film was useful for acetaminophen (AC) determination. In 0.2 mol L−1 phosphate buffer (pH=9), the GCE without modification exhibited the smaller photocurrent (0.86 μA) when compared with GCE modified with 1.0 mg mL−1 or 2.0 mg mL−1 BiVO4 nanoparticles suspension (5.9 and 34 μA, respectively). Based on the photocurrent signal generated through the interaction between GCE, BiVO4 and the energy of visible light a chronoamperometric method for AC determination was developed. The AC linear range concentration from 0.099 to 0.99 μmol L−1 and limits of detection and quantification of 0.027 and 0.091 μmol L−1, respectively, was obtained. The proposed method was applied to the AC determination in commercial drugs and tap water with satisfactory accuracy and precision. Moreover, the PEC construction was easy and had a short response time, which might confer higher sample throughput for the method.
