The specific interaction between antibody and antigen is detected by using a transducer and an electrical signal is measured. This specific interaction between these molecules makes immunosensor very attractive for several applications in different fields. Electrochemical immunosensors are successful devices in selective and sensitive detection of several analytes. Electrochemical transducing methods such as voltammetric, potentiometric, conductometric or impedimetric have been utilized in different applications due to their excellent properties such as being low-cost, sensitivity and simplicity. In this chapter, the fundamentals of electrochemical immunosensors are summarized and different applications in food, environmental and clinical analyses are investigated and discussed.en10.1016/bs.acc.2019.04.006info:eu-repo/semantics/closedAccessFree Impedimetric ImmunosensorHighly Sensitive DetectionDisposable Amperometric ImmunosensorFunctionalized Graphene OxideScreen-Printed ImmunosensorLabel-FreeGold NanoparticlesHuman SerumUltrasensitive DetectionCarbon NanotubesBook Chapter92157N/AWOS:0005017249000022-s2.0-8506614145531472751Q4
