Functionalized Nanomaterial-Based Electrochemical Sensors for Point-of-Care Devices

Abstract

<div>Electrochemical sensors used for the detection of specific biomolecules have</div><div>attracted great attention in recent years due to their high sensitivity, selectivity, simple</div><div>preparation, and fast response. In recent years, the integration of biological components</div><div>into analytical tools, especially in biomedical research, has become a prerequisite for</div><div>the early diagnosis of many diseases. In addition, enabling early diagnosis and</div><div>treatment of diseases provides improved health outcomes and rapid medical decisionmaking.</div><div>Here, we present the classification of biosensors and general concept,</div><div>materials used in electrochemical sensors, their advantages, disadvantages, and main</div><div>strategies in electrochemical biosensor technology such as electrodes and supporting</div><div>substrates, materials for the bioreceptor materials for improved sensitivity and</div><div>selectivity. This book chapter is focused on the functionalization of nanomaterials</div><div>developed in recent years aimed at electrochemical biosensors and their</div><div>functionalization for point of care devices. The various point of care device examples</div><div>have been tried to form an idea about the usage areas.</div>
