“…Voltammetry is a technique measuring current flows in an electrochemical cell by controlling the applied voltage. There are several types of voltammetry, and the most common one is cyclic voltammetry, which can be used to qualitatively and quantitatively measure electrochemical properties of an electrochemical cell or a chemical species [ 35 ]. Electrochemical immunosensors have been developed to determine HBV biomarkers utilizing cyclic voltammetry (CV), square-wave voltammetry (SWV), and differential pulse voltammetry (DPV) as signal transducers.…”

Hepatitis B virus (HBV) still remains a major global public health problem. One-half to one-third of the total HBV infected people died due to late detection of HBV. Serological antigen and viral HBV detections can help in the diagnosis, referral, and treatment of HBV. Available methods for HBV detection mostly used bulky instruments. Miniaturization of devices for HBV detection has been started by narrowing down the size of the devices. Several methods have also been proposed to increase the selectivity and sensitivity of the miniaturized methods, such as sandwich recognition of the biomarkers and the use of nano- to micro-sized materials. This review presents recent HBV detections in the last two decades from laboratory-based instruments towards microfluidic paper-based analytical devices (µPADs) for point-of-care testing (POCT) purposes. Early and routine analysis to detect HBV as early as possible could be achieved by POCT, especially for areas with limited access to a central laboratory and/or medical facilities.

“…Scan rate is given by the rate of voltage variation over time during each cycle. The voltage is applied between the working electrode and reference electrode 13 and current is measured between working electrode and counter electrode as shown in figure 2. Cyclic voltammetry consists of variation of working electrode's potential using a triangular wave form as shown in figure 3 .In the initial forward scan between t 0 to t 1 , the potential is increased.…”

Electrochemistry is defined as the branch of chemistry that examines the phenomena resulting from combined chemical and electrical effects. This paper covers some of the common voltammetry techniques which are currently in use. Cyclic voltammetry is a widely used technique in electrochemistry .The cyclic voltammetry is a powerful tool to study the electrochemical behavior of a system by systematic study of current-voltage measurements of a given electrochemical cell. Brief study of cyclic voltammetry and the analysis of an electrochemical cell from cyclic voltammogramis described.

“…Most common working electrodes (WEs) for voltammetric or amperometric electroanalysis are platinum (Pt), gold (Au) or glassy carbon (GC) disks. 1,2 They are easily obtainable from global suppliers of electrochemistry accessories as pen-like electrochemical (EC) tools. Alternatively, potential users may make them 'in-house' by sealing purchased noble metal wires or GC rods in a cylindrical glass or durable polymer housing with cured epoxy resins and exposing the conductive assembly tip through a sequence of ne emery paper abrasion and alumina polishing steps.…”
