“…Furthermore, by using flexible substrates, screen printed electrodes can be easily integrated into a range of different sensing technologies -from the worlds of sports and fashion to automotive and healthcare [44]. Be this as it may, current screen-printing approaches for the detection of Tyr use rigid ceramic substrates, expensive metal nanoparticle conductive inks and stiff metal or metal oxidebased sensitive materials, that are neither sustainable nor suitable for single-use disposable or wearable sensors (Table 1) [3,6,7,10,11,17,19].…”

The process of growth, development, and reproduction cannot take place in a live body without the presence of amino acids (AAs) since they are necessary for appropriate functioning. Detection of AAs in pharmaceutical and food samples is required to ensure quality, quantity, and efficacy. The AAs generally do not contain chromophores; hence their chromatographic analysis requires derivatization. The research papers published in the last few years were used to compile this manuscript. This manuscript covers various analytical, bioanalytical, and electrochemical approaches used in the identification of AAs. The analytical techniques like high‐performance liquid chromatography, ultra‐performance liquid chromatography, etc., and the hyphenated analytical techniques like liquid chromatography‐mass spectrometry, ultra‐performance liquid chromatography‐electrospray tandem mass spectrometry, and hydrophilic interaction ultra‐performance liquid chromatography are also discussed. This manuscript also briefly outlines the electrochemical analytical techniques including sensors and biosensors. This review article will be useful to the researcher working in the area of the development of analytical techniques for the detection of AAs.

“…Several mod ified electrodes have been used for the determination of dopamine, tyrosine and ascorbic acid making use of different materials like metal nanoparticles, conducting polymers and carbon [44][45]. NiO nanoparticles have also been used to design many electrochemical sensors to determine amino acids, neurotransmitters, sugars and other bio-molecules [46][47][48][49][50][51].…”

In this work, an electrochemical sensor is fabricated by decorating the surface of graphite electrode with NiO/graphene (NGMG) nanoparticles and employed for the detection of dopamine (DA), tyrosine (Tyr) and ascorbic acid (AA). The structure and morphology of prepared NiO nanoparticles are examined by XRD,SEM, FTIR and Raman techniques. The electrochemical properties have been investigated by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoamperommety. The modified electrode is prepared by a simple drop casting method. The electrode shows good electro catalyticactivity towards oxidation of DA, Tyr and AA. It successfully separates the oxidation current signals of AA, DA and Tyr into clearly visible three distinct oxidation peaks compared to a single, overlapped oxidative peak on bare graphite electrode. The peak potential difference between AA-DA, DA-Tyr and AA-Tyr is 228 mV, 303 mV and 565 mV respectively in cyclic voltammetry (CV) studies and the corresponding peak potential separations are 243 mV, 318 mV and 561 mV respectively in differential pulse voltammetry (DPV). It is found that oxidation mechanism of DA, AA and Tyr on NGMG are different owing to a different type of interaction of the modified layer with the bio-analytes. The modified electrode, NGMG has high selectivity and sensitivity in addition to other factors like low cost, convenient and a hassle free electrochemical method for simultaneous determination of DA, AA and Tyr in their ternary mixture.
