Gold Nanoparticle/Polymer/Enzyme Nanocomposite for the Development of Adenosine Triphosphate Biosensor

摘要

39.1 Introduction Biosensors represent a group of advanced analytical devices suitable for the determination of a variety of substances in liquid or gaseous samples. Biosensors consist of a biomaterial and a transducer in close contact with each other [24]. The biomaterial (e.g., enzymes) serves as a sensing element, which selectively interacts with a target substance, while the transducer (e.g., an electrode in the case of electrochemical biosensors) records the signal issued from the biomaterial/analyte interaction.
