A facile approach for preparation of molecularly imprinted polymers layer on the surface of carbon nanotubes

Molecularly imprinted polymer grown on multiwalled carbon nanotube surface for the sensitive electrochemical determination of amoxicillin

“…In most reports, the functional monomer or initiator is firstly immobilized on MWCNTs surface by using covalent bonding before the preparation of MIP [32][33][34][35][36][37][38]. However, a few reports focus on no-covalent bonding [39][40][41]. For instance, Qian et al reported the in situ chemical oxidative polymerization of pyrrole on MWCNT surface for the preparation of novel MWCNTs@MIP [40].…”

A facile approach for synthesizing molecularly imprinted graphene for ultrasensitive and selective electrochemical detecting 4-nitrophenol

“…In many literatures, 1 mM MAA, 2 mM EGDMA and 20 mg AIBN were chosen to synthesize MIPs. [24] So, in our experiment the same ratio of the polymerizing monomer was used to prepare MIPs on GR/NVC. As it is supposed that the vinyl group of NVC adsorbed on graphene surface directs the selective polymerization of MAA and EGDMA to obtain the final GR/MIPs composite, the amount of NVC adsorbed on graphene should have some effect on the amount of MIPs on the surface of graphene, which in turn affects the electrochemical behavior of the sensor.…”

“…Previous literatures have reported that the introduction of vinyl groups onto the surface of supporting substrate not only allow the substrate to combine with the MIP film via a strong interaction, but also direct the selective imprinting polymerization on the supporting substrate via the copolymerization of vinyl end groups with polymerizable monomers [22,23]. Zhang et al successfully utilized FRP to synthesize CNTs-MIPs composite by noncovalently attaching 9-vinylanthracene to CNTs, forming homogeneous and high-density vinyl groups on CNTs surface, which is favorable to the formation of continuous and nanoscale MIP layer on the surface of carbon nanotubes (CNTs) [24]. It is expected that such a strategy could be retrofitted to graphene sheets despite of the structural differences between graphene sheets and CNTs.…”

Hollow fiber-supported graphene oxide molecularly imprinted polymers for the determination of dopamine using HPLC-PDA

“…[9][10][11][12][13] Recently, a novel molecular imprinting technique on the surface of nanomaterials was applied for the preparation of surface MIPs with favorable selectivity. For example, surface MIPs were synthesized on the surface of carbon nanotubes (CNTs) [14][15][16][17][18] and graphene, [19][20][21][22][23][24][25][26][27] and most of these composites were utilized to detect the target analytes. A novel composite of SiO 2 -coated graphene oxide (GO) and molecularly imprinted polymers was synthesized for the electrochemical sensing of dopamine by Zeng et al 19 However, only a few studies concern sample pretreatment using MIPs based on GO.…”
