“…21,22 Different kinds of methods have been developed for the detection of Tyr such as HPLC, 23 capillary electrophoresis 24 and others. [25][26][27] All of LD, PA and Tyr are commonly used drugs in PD treatment. Especially, Tyr and LD have quite similar chemical structures and physiological functions.…”

“…MATLAB can be linked with electrochemistry by the chemometricians and those electrochemists who are familiar with MATLAB-based chemometrical approaches. In electroanalytical projects, the sensor is usually modified with different materials to enhance the selectivity and sensitivity of the developed method [91][92][93][94][95][96][97][98][99][100][101][102][103] [104][105][106].The double layer charging current, which is generated with the change of potential on the working electrode surface, causes interference with the accurate measurement of the faradaic current and restricts the detection limit [107,108]. Since the analytical signal is usually generated by changing the potential in most electrochemical techniques, it is inevitable to include the charging current in the measured signal of an electroanalytical system.…”

MATLAB (MATrix LABoratory) is a multi-paradigm numerical computing environment and fourth-generation programming language. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, Java, Fortran and Python. Electrochemistry is a branch of chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice versa. MATLAB has obtained a wide range of applications in different fields of science and electrochemists are also using it for solving their problems which help them to obtain more quantitative and qualitative information about systems under their studies. In this review, we are going to cast a look on different applications of MATLAB in electrochemistry and for each section, a number of selected articles published in the literature will be discussed and finally, the results will be summarized and concluded.

“…Generally, after developing a new analytical method and validating its performance for the analysis of synthetic samples, its performance is compared with a reference method to verify its capability for the analysis of real samples. 52 Then, the newly developed analytical method could be suggested as a reliable method for routine analyses. Regarding this important step, we have also applied HPLC analysis of the cheese, egg and yogurt as real samples towards tyrosine determination and its results are presented in Table 3.…”

Numerous techniques have focused on the ability of p-sulfonated calix[4]arene to form complexes with tyrosine. Scanning electron microscopy and Fourier transform infrared spectroscopy and ultraviolet spectroscopy were utilized to study the organization and molecular structure of different layers of the electrode surface. A novel and ultrasensitive electrochemical sensor based on p-sulfonated calix[4]arene modified gold electrode for determination of tyrosine in some high tyrosine foods including cheese, eggs and yogurt was reported. P-sulfonated calix[4]arene not only increased the specific surface area of the modified electrode, but also improved the enrichment ability of tyrosine. The modifications were characterized by electrochemical impedance spectroscopy, cyclic voltammetry and molecular modeling calculation. Under optimal conditions, the sensor detected tyrosine with a limit of detection of 1.5×10 −9  mol L −1. The sensor was able to selective determination of tyrosine even in the presence of common interference. The tyrosine guest molecule had a stronger π…π interaction with p-sulfonated calix[4]arene, which accelerated the electron transfer rate of tyrosine on the electrode surface, and increased the electrochemical activity. Therefore, the biosensor was highly selective. The sensor also showed good operational stability, sensitivity, repeatability and reproducibility.
