Simultaneous determination of five bioactive constituents in Rhizoma Chuanxiong by capillary electrophoresis with a carbon nanotube-polydimethylsiloxane composite electrode
Abstract(#br)A carbon nanotube (CNT)-polydimethylsiloxane (PDMS) composite electrode was developed for the capillary electrophoretic determination of the bioactive constituents in Rhizoma Chuanxiong , a traditional Chinese medicine. The novel composite electrode was fabricated on the basis of the in situ polyaddition of curing agent-containing dimethyl siloxane oligomer in the presence of CNTs in the inner bore of a piece of fused silica capillary under heat.
