A three-dimensional hybrid of CdS quantum dots/chitosan/reduced graphene oxide-based sensor for the amperometric detection of ceftazidime

As electrochemical measuring instruments, screen-printed electrodes (SPEs) are constructed via a technology called thick film deposition onto plastic or ceramic substrates, allowing for simple, inexpensive, and rapid on-site analysis with high reproducibility, sensitivity, and accuracy. Numerous substances such as gold, silver, platinum, and carbon are applied for electrode construction, enabling the analyst to design the best device based on its purpose to determine an analyte’s selectivity and sensitivity. Thus, in the current review, we report the latest results and analyses conducted over the past eight years (2015–2022) on the expansion of SPE electrochemical biosensors, including aptasensors, immunosensors, DNA sensors, and enzymatic biosensors. Such expansion has resulted in new possibilities for the identification, distinction, and quantification of biocompounds, drugs, enzymes, etc. Therefore, in this paper, we review the role of different nanomaterials in manufacturing on-screen electrode methods as well as strategies for the future stable diagnosis of biorecognition elements.
