An Overview on Quantum Dot-based Nanocomposites for Electrochemical Sensing on Pharmaceutical Assay

Quantum dots (QDs) are one of the first nanotechnological materials to be integrated with sensor technologies and have been widely anticipated to eventually find application chances in several commercial pharmaceutical and clinical products. They are one of the most important developments in the rapidly growing world of material science technology. The excellent properties of QDs may allow the design of simple, precise, and inexpensive electrochemical methods for the detection of pharmaceuticals. Electrochemical techniques offer accuracy, high sensitivity, low cost, simplicity, ease of preparation of the samples in a very short time, and speed of analysis. The most commonly used voltammetric techniques are differential pulse voltammetry, cyclic voltammetry, square wave voltammetry, and stripping voltammetry. The purpose of this review is to show and communicate the advantages and uses of QD applications used in drug analysis. Besides, the present application methods of QDs to the pharmaceutical analysis and their related parameters were summarized between 2012 and 2021 years and summarized as a table.
