The object of study is the anti-Müllerian hormone, a biomarker of the state of the female reproductive system. Two methods of antibody immobilization are considered: high-affinity streptavidin–biotin binding and physical adsorption. Oriented immobilization demonstrates the absence of nonspecific interactions and an increase in assay sensitivity. An increase in the size of nanoparticles in the immunoconjugate leads to a decrease in the limit of detection.
