Structure of the receptor layer in electrochemical immunosensors. Modern trends and prospects of development

Literature data on the modern state and prospects for the development of research in the area of receptor layer immobilization in electrochemical immunosensors were examined and systematized. The first section of the review is devoted to structural features and functions of biological immunoreceptors, viz. , antibodies or their fragments. The main methods of antibody immobilization on the working electrode surface are considered in detail in the second section. The prospects for the development of electrochemical immunosensors are discussed in the third section of the review.
