Noncovalent immobilization of MnP from on carbon nanotubes

Jiaxi LI , Xianghua WEN ,

Frontiers of Environmental Science & Engineering 2009, Volume 3, Issue 3, Pages 294-299 doi: 10.1007/s11783-009-0041-4

Abstract: Manganese peroxidases (MnP) from were adsorbed onto multi-walled carbon nanotubes (MWNT). Four different loadings of MnP on MWNTs were investigated, and the maximum enzyme loading of 47.5 µg/mg of MWNTs was obtained in 12 h. The adsorbed MnP showed a catalytic activity of up to 0.1 U/mg of the weight of the system of MnP/MWNTs, with 23% of its original activity retained. The AFM image of the adsorbed enzymes indicated that a layer of MnP covered the surface of the MWNTs and retained its original three-dimensional shape. Amino-based nonspecific interactions may play the dominant role in the adsorption of MnP on MWNTs.

Surface molecularly imprinted polymers for solid-phase extraction of (--)-epigallocatechin gallate from toothpaste

Yunling Gao,Ying Hu,Kejian Yao

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 4, Pages 467-478 doi: 10.1007/s11705-015-1526-2

Abstract: Surface molecularly imprinted polymers (SMIPs) have been synthesized to selectively determine (−)-epigallocatechin gallate in aqueous media. SMIPs were prepared using a surface grafting copolymerization method on a functionalized silica gel modified with -cyclodextrin and vinyl groups. The morphology and composition of the SMIPs were investigated by scanning electron microscopy, Fourier transform-infrared spectroscopy and thermogravimetric analysis. In addition, the molecular binding capacity, recognition properties and selectivity of the SMIPs were evaluated. The imprinted polymers were found to have a highly specific recognition and binding capacity for (−)-epigallocatechin gallate in aqueous media which is the result of the hydrophobic properties of the -cyclodextrin and the hydrogen-bonding interactions of methacrylic acid. The SMIPs were successfully employed as solid-phase extraction adsorbents prior to the HPLC determination of (−)-epigallocatechin gallate in toothpaste. The HPLC analysis had a linear dynamic range of 0.5–50.0 µg?mL with a correlation coefficient of 0.9998 and the recoveries ranged from 89.4% to 97.0% with relative standard deviations less than 4.8%. The limit of detection and limit of quantification were 0.17 and 0.33 µg?mL , respectively. The method provides a promising approach for the preparation of selective materials for the purification and determination of complex samples.
