Zeta potential based colorimetric immunoassay for the direct detection of diabetic marker HbA1c using gold nanoprobes.
A one-step homogeneous colorimetric immunoassay format coupled with zeta potential measurements for determination of specific diabetic biomarker glycated hemoglobin (HbA1c) using functionalised gold nanoparticles as bioprobes is reported. The assay exhibi.....
