The Applications of Nanomaterials in Electrochemical Immunosensors

In recent decades, the research of nanomaterials in the fields of materials science, physics and chemistry has become a global hottest topics, its potential importance is unquestioned. Nanomaterials with large surface areas, high surface - activity, good bioeompatibility, strong adsorption capacity and great catalytic activity have been widely used to immobilize the biomole- cules, concentrate the analytes, detect and amplify the signals. Thus the sensitivity of immunosensors can be enhanced This review addresses recent advances in nanomaterials - based electrochemical immunosensors and summarizes the main functions of nanomaterials in these sensor systems.
