“…Varmira et al developed an electrochemical method for ultrasensitive detection of AA using CNT and room temperature IL (1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide) composite because of their compatible π–π or cation−π interaction. Further, the chitosan-IL composite was also used since the biopolymer is known to accumulate metallic NPs using electrostatic attraction, chelation, and ion exchange mechanisms, whereas IL reduced the interfacial tension . This NM biosensor was designed by the constructive layering of MWCNTs IL on GCE followed by chitosan- IL.…”

Acrylamide, a food processing contaminant with demonstrated genotoxicity, carcinogenicity, and reproductive toxicity, is largely present in numerous prominent and commonly consumed food products that are produced by thermal processing methods. Food regulatory bodies such as the U.S. Food and Drug Administration (U.S. FDA) and European Union Commission regulations have disseminated various acrylamide mitigation strategies in food processing practices. Hence, in the wake of such food and public health safety efforts, there is a rising demand for economic, rapid, and portable detection and quantification methods for these contaminants. Since conventional quantification techniques like liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) methods are expensive and have many drawbacks, sensing platforms with various transduction systems have become an efficient alternative tool for quantifying various target molecules in a wide variety of food samples. Therefore, this present review discusses in detail the state of robust, nanomaterials-based and other bio/chemical sensor fabrication techniques, the sensing mechanism, and the selective qualitative and quantitative measurement of acrylamide in various food materials. The discussed sensors use analytical measurements ranging from diverse and disparate optical, electrochemical, as well as piezoelectric methods. Further, discussions about challenges and also the potential development of the lab-on-chip applications for acrylamide detection and quantification are entailed at the end of this review.

“…When stored at 4 • C, the electrode can be used 120 times in 100 days with acceptable repeatability and stability. Varmiraa et al also constructed an effective electrochemical biosensor based on Hb-dimethyldioctadecyl ammonium bromide (DDAB)/Pt-Au-palladium three metallic alloy NPs chitosan-1-/ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide/MWCNTs-IL/glassy carbon electrode (Hb-DDAB/PtAuPd NPs/Ch-IL/MWCNTs-IL/GCE) for selective and sensitive determination of AA in food samples ( Figure 7B) [111]. The developed sensor can determine AA in two linear concentration ranges of 0.03-39.0 nmol L −1 and 39.0-150.0 nmol L −1 using SWV with LOD of 0.01 nmol L −1 and can selectively detect the target AA even in the presence of high concentrations of common interferences, confirming its highly selectivity.…”

Acrylamide (AA) is produced by high-temperature processing of high carbohydrate foods, such as frying and baking, and has been proved to be carcinogenic. Because of its potential carcinogenicity, it is very important to detect the content of AA in foods. In this paper, the conventional instrumental analysis methods of AA in food and the new rapid immunoassay and sensor detection are reviewed, and the advantages and disadvantages of various analysis technologies are compared, in order to provide new ideas for the development of more efficient and practical analysis methods and detection equipment.

“…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.
