The initial sample, together with the conjugated antibody bound to the target analyte, migrates further along the test strip into the detection area. A competitive format is utilized for finding analytes in which the analyte is too little for 2 antibodies to bind concurrently, such as vitamins and antibiotics. In a competitive assay, the test line includes the target analyte molecule (generally a protein-analyte facility). If the analyte is absent in the example, the nanoparticle antibody conjugates will bind to the analyte at the examination line, resulting in high signal strength. If the target analyte exists in the example, the analyte will bind to the antibodies on the nanoparticle surface area and also prevent the nanoparticle from binding to the test line.
