Recent trends in the applications of polymer composite modified electrodes for biosensors

Abstract

Biosensors have gained increasing significance in recent years on account of their many advantages, including low cost, simplicity of use, and portability. They are successful analytical sensing tools in detection of target analytes in various fields, such as clinical diagnosis, the food industry, environmental monitoring, and biosecurity. Among different immobilization support materials, polymer nanocomposites have been preferred in the construction of biosensors/sensors due to their promising characteristics of high mechanical and electrical features, good environmental stability, low cost, and good electrical conductivity. This chapter summarizes the recent advances in polymer nanocomposite modified biosensors and investigates their applications in biosensor fabrication. © 2023 Elsevier Ltd. All rights reserved.
