Iron oxide@mesoporous carbon architectures derived from an Fe(ii)-based metal organic framework for highly sensitive oxytetracycline determination

Abstract

An Fe-MOF-derived Fe3O4@mC-based aptasensor was constructed to sensitively and selectivity detect trace oxytetracycline and a low detection limit was obtained.

Influence of Fe(III)‐OTC complex on degradation of OTC with Fe(II)/H2O2 under simulated solar light

“…Owing to the complexity of OTC structure (Fig. 2), OTC was a complex agent (Ghandour et al ., 1992; Song et al ., 2017), which could form stable complexes with some metal ions, such as OTC with Fe 3+ . In this study, OTC‐Fe (II) or OTC‐Fe (III) might play a role in the degradation of OTC.…”

Quantification of EGFR and EGFR-overexpressed cancer cells based on carbon dots@bimetallic CuCo Prussian blue analogue

“…The increase of the R ct value for the CD@CuCoPBA/AE indicates that the CD@CuCoPBA nanocomposite displays relatively poor conductivity. 38 Aer the EGFR aptamer immobilization, the R ct value of the modied electrode increases from 0.321 to 1.058 kohm suggests that the EGFR aptamer was successfully immobilized onto the CD@CuCoPBA/AE, further hampering the charge transfer. 39 When detecting EGFR, the R ct value further increases because the specically binding between EGFR and the aptamer to form a tight complex.…”

Metal‐Organic Gel‐Derived Co/CoO/Co3O4 Composite for the Electrochemical Detection of Diethylstilbestrol

“…Generally, as the central part of electrochemical sensors, electrode materials with excellent physical and chemical properties, such as good stability, large surface area, versatile structure, high conductivity and facile synthesis, are highly desirable . Glass carbon electrode with modified materials could increase the contact efficiency with substrates and accelerate the electrode interface reaction . The recently reported electrode modified materials, such as Au nanoparticles decorated MnO 2 , N‐doped porous carbon, copper‐nitrogen‐doped graphene, can effectively reduce the charge transfer resistance, which could be attributed to the introducing of conductive active species of noble metal or carbon materials.…”
