We present, herein, a data acquisition and analysis methodology based on frequency resolved immittance function analysis. Ultimately, this enables both a maximization of assay sensitivity and a reduction in assay acquisition time by an order of magnitude.12137-12144engArtigo10.1021/acs.analchem.5b02976Acesso restrito2-s2.0-84950107826
