Analysis of the Kinetics of Antigen-Antibody Interactions and Fractal Dimension in Biosensors

Abstract

Sensitive detection systems (or sensors) are required to distinguish a wide range of substances. Sensors find application in the areas of biotechnology, physics, chemistry, medicine, aviation, and environmental control. Biosensor systems have different operating parameters, including stability, specificity, response time, selectivity, and regenerability. A better understanding of the mode of operation of these parameters would lead to increasing biosensor performance efficiency. Separation or the detection of reactants can be performed by the solid-phase immunoassay technique (antibody—antigen reaction) or by immobilizing enzymes on appropriate surfaces (enzyme—substrate reaction). There is a need to characterize the reactions occurring at the biosensor surface by paying attention to both the reaction and the sensing element (surface).
