A simple method has been devised for immobilization of acetylcholinesterase (AChE)-covalent bonding to a multiwall carbon nanotube (MWNT)-cross-linked chitosan composite (CMC)-and a sensitive amperometric sensor for rapid detection of acetylthiocholine (ATCl) has been based on this. Fourier-transform infrared spectroscopy proved that the native structure of the immobilized enzyme was preserved on this chemically clean and homogeneous composite film, because of the excellent biocompatibility and non-toxicity of chitosan. Glutaraldehyde was used ...
