A Signal‐Amplified Electrochemical Immunosensor Based on Prussian Blue and Pt Hollow Nanospheres as Matrix

Abstract: Through electrodepositing Prussian blue (PB) and chitosan (CS), then casting Pt hollow nanospheres (HN-Pt) and assembling CA19-9 antibody on the electrode surface, an immunosensor was achieved. A new signal amplification strategy based on PB and HN-Pt toward the electrocatalytic reduction of H 2 O 2 was employed when performing the determination. The resulting immunosensor showed a high sensitivity, broad linear response to carbohydrate antigen 19-9 (CA19-9) in two ranges from 0.5 to 30 and 30 to 240 U mL À1 w… Show more
