Optimization results for the antibody diluents, resuspension solution of the AuNP-mAb probe (abbreviated as RSS) and dilution factor of the coating antigen (abbreviated as DF). (a) Chromatographic results for negative samples and positive samples tested with AuNP probes prepared with different antibody diluents. (b) Chromatographic results for negative samples and positive samples tested with AuNP probes prepared with different resuspension solutions. (c) Chromatographic results for the negative samples and positive samples tested by strips prepared with different concentrations of coating antigen. Negative samples: blood samples that did not contain FAMs; positive samples: blood samples with 0.5 mg/mL FAMs
