| Abstract: |
| Molecularly imprinted polymer (MIP) is grafted to multi-walled carbon nano-tube (MWCNT), which this novel composite (Multi-walled carbon nanotubes-molecularly imprinted polymer, MWCNT-MIP) has a higher binding capacity, greater selectivity and faster binding kinetics, and it is of concern in recent years. In this paper, the characteristics of the MIP and MWCNT and their applications in sample pretreatment of veterinary drugs residues analysis are summarized. The technique of multi-walled carbon nanotubes grafted molecularly imprinted polymer and its application in veterinary drug residue analysis are mainly described. In addition, the advantages of MWCNT-MIP in SPE procedure for residues analysis and several problems are discussed, and expect it can provide reference for the further studies of MWCNT-MIP synthesis and its application in residues analysis of complex matrices. |
