文摘
- •
A CL biosensor for Lys was obtained coupled with SMIP based on ILs-Fe3O4@DA/GO/β-CD.
- •
Absorption capacity of ILs-Fe3O4@DA/GO/β-CD-SMIP to Lys reached up to 101 mg/g.
- •
The adsorption equilibrium was reached within 10 min.
- •
Adsorption model followed Langmuir isotherm.
- •
The CL system was luminol, K3[Fe(CN)6] and NaOH solutions.
