a Binding assay for IgG measurements with PEGylated functionalized surface of nanoholes array with TM mode. b Histograms of the resonance shift for different IgG concentrations with multiple measurements for each case. The error bars represent the deviation standard from the average value for each measurement. c Average resonance shift for different IgG concentrations and fitting of the binding assay in red curve. The error bars represent the maximum deviation from the average value of multiple measurements for each IgG concentration. The value 3σ is highlighted by the dashed line both in b and c.
