Abstract
This study reports a micro-system capable of sensing nicotine (NIC) using a new combination of microfluidics, electrochemical sensing, and molecularly imprinting polymer (MIP) techniques. The sensing system can detect the concentration of NIC by fabricating NIC-imprinted TiO 2 sites on a microelectrode. The modular design of the sensing systems allows us to integrate a microfluidic control module and an electrochemical sensing module for a sensitive and selective detection of NIC in an automatic format. © 2006 Society for Chemistry and Micro-Nano Systems.
