Coordination of Nanoconjugation with an Antigen/Antibody for Efficient Detection of Gynecological Tumors

Figure 1

Schematic representation of the detection of SCC-Ag on the amine-modified IDE surface. (a) SCC-Ag-GNP detection on the SCC-Ag antibody-modified surface. The antibody was immobilized on the APTES-modified surface, and then, SCC-Ag-GNP interacted with the antibody. (b) SCC-Ag-antibody-GNP was immobilized on the APTES-modified surface, and then, SCC-Ag interacted on the surface, enabling its detection.
