摘要: This study describes a green, facile and low cost approach for imprinting protein on the surface of multi-walled carbon nanotubes (MWNTs) using papain as template, dopamine functional monomer. By simply mixing MWNTs, dopamine, template in weak alkaline aqueous solution, thin adherent polydopamine (PDA) film imprinted with was spontaneously obtained MWNTs to produce nanomaterials (MWNTs@MIPs). The MWNTs@MIPs were characterized Fourier transform infrared spectrometer (FT-IR), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) transmission (TEM). adsorption process towards investigated detail. effects concentration monomer polymerization time, extraction optimized. prepared show fast binding kinetics, high capacity acceptable specific recognition behavior proteins. Furthermore, stability regeneration also investigated, which indicated that had good reusability. recognizing coupled one-step preparation make attractive separation recognition.
