Activated carbon (AC), which has attracted considerable attention as an electrode material, holds much promise for electroanalysis. The unique physical and chemical properties of AC, such as the high surface area, good thermal and electrical conductivity, good anti-causticity, high stability, and low cost make it an electrode material which can generate large profits from a commercialization perspective. Number of biomassderived ACs (BACs) with a variety of pore sizes, porosity, morphology, and crystallinity have been prepared from a range of sources of biomass, including agro-wastes on a large scale. BACs exhibit unique and tunable electrochemical properties depending on their physicochemical properties and thus, have found number of applications in industries, pharmaceutical industry, and water treatment plants. From an electrochemical perspective, researchers have demonstrated the impact of BAC as an electrode material for detecting electroactive drugs, environmental pollutants, and developing electrochemical biosensors. Hence, this paper thoroughly reviews and summarizes the literature published within the last ten years, focusing specifically on the types of analytes detected and electrochemical techniques employed and evaluating their performance (in terms of sensitivity, selectivity, and dynamic ranges) and feasibility for electroanalysis. In addition, the review outlines some constructive advice and scope for further research.

“…So far, di erent analytical methods have been utilized for the detection of PC; chemiluminescence [4], high-performance liquid chromatography [5], mass spectrometry [6], spectrophotometry [7], and electrochemical sensors have been used [8]. Most of the techniques are di cult, time-consuming processes, and they generally demand professional apparatus, except for electrochemical sensors [5,9,10].…”

Paracetamol (PC) is widely used for defensive and medicinal purposes for human beings. But their deposition in the human body will persuade thoughtful health risks. So, the enhancement of sensitive and selective techniques for the easy and fast detection of PC is extremely fundamental. Multilayered electroactive polyaniline-ZnO nanocomposite (NC) film was developed for PC detection which was based on the oxidation of PC with polyaniline doped zinc oxide on a glassy carbon electrode (PANI/ZnO/GCE). PANI and PANI/ZnO NCs were fabricated by both electrochemical and in-situ oxidative chemical polymerization methods. The morphology of PANI/ZnO shows that the polymer was distributed on the surface of ZnO, and the XRD pattern confirms that the average size calculated was 7.48 nm for PANI/ZnO. From UV-Vis measurements, the PANI/ZnO composite shows a redshift relative to PANI and ZnO. Moreover, FT-IR spectra show that chemical bonds and stretching are assigned to different peaks. Using differential pulse voltammetry, the fabricated PANI/ZnO/GCE electrochemical sensor displays good analytical performance for PC with detection limits of 4 × 10−8 M and a sensitivity of 2.571 mA/1 × 10−8 M with a linear concentration of PC within the range of 1.0 to 7.0 × 10−8 M.

“…Using computers as research tools allows performing a large number of calculations and simulations in order to select the most suitable structure and composition of functional monomer, template, crosslinker, and porogen/solvent [ 21 ]. The core of such calculations is based on input data related to the chemical composition, the structure at the atomic scale, the distribution of electronic charges leading to dipole formation as well as weak, long range dispersion interactions governed by hydrophobic van der Waals forces [ 22 ]. All these factors contribute to a direct picture of a molecular association and the corresponding interaction energy.…”

An Update on Molecularly Imprinted Polymer Design through a Computational Approach to Produce Molecular Recognition Material with Enhanced Analytical Performance

Molecularly imprinted polymer (MIP) computational design is expected to become a routine technique prior to synthesis to produce polymers with high affinity and selectivity towards target molecules. Furthermore, using these simulations reduces the cost of optimizing polymerization composition. There are several computational methods used in MIP fabrication and each requires a comprehensive study in order to select a process with results that are most similar to properties exhibited by polymers synthesized through laboratory experiments. Until now, no review has linked computational strategies with experimental results, which are needed to determine the method that is most appropriate for use in designing MIP with high molecular recognition. This review will present an update of the computational approaches started from 2016 until now on quantum mechanics, molecular mechanics and molecular dynamics that have been widely used. It will also discuss the linear correlation between computational results and the polymer performance tests through laboratory experiments to examine to what extent these methods can be relied upon to obtain polymers with high molecular recognition. Based on the literature search, density functional theory (DFT) with various hybrid functions and basis sets is most often used as a theoretical method to provide a shorter MIP manufacturing process as well as good analytical performance as recognition material.
