In this work, the multi-walled carbon nanotubes were covalently functionalized with l-histidine (His–MWNTs) as online pseudospecific affinity adsorbent for immunoglobulin G (IgG) separation and purification with a simple surface modification method, using 1-ethyl-3-(3-dimethyaminopropyl) carbodiimide hydrochloride (EDC) and N-hydroxysuccinimde (NHS). The affinity of the His–MWNTs toward IgG was investigated...
The multi-walled carbon nanotubes (MWNTs) coated quartz wool (MWNTs/QW) prepared by dynamic layer-by-layer self-assembly was used as solid-phase extraction (SPE) absorbent for on-line separation and preconcentration of lysozyme in egg white. The coating procedures were performed continuously in a flow system operated by a set of sequential injection devices. The quartz wool was placed in a microcolumn...
