818Imprinted polymer/Fe3O4 micro-particles decorated multi-layer graphite paper: Electrochemical and colorimetric dual-modal sensing interface for aloe-emodin assayhttps://doi.org/10.1016/j.snb.2020.128672Metal oxideFe3O4 micro-particles were directly synthesized on a multi-layer exfoliated graphite paper (EGP) by the in-situ hydrothermal approach, which was subsequently modified with a layer of molecularly imprinted polymer (MIP) using pyrrole and aloe emodin (AE) as monomer and template, respectively.
