A renewable amperometric immunosensor for phytohormone β-indole acetic acid assay
Abstract
A rapid, convenient and accurate method using a sol–gel–alginate–carbon composite electrode (SACE) is described for the determination of β-indole acetic acid (IAA) in plant samples. The determination is based on an enzyme-linked competitive immunoreaction between free IAA and IAA labeled with HRP to bind on the anti-IAA IgG immobilized on the SACE surface. The response signal expressed as percentage current reduction (CR%, y) is linearly …
