TLDR
An electrochemical impedance method to detect concentrations of the local anesthetics Levobupivacaine was implemented and the concentration could be detected to 1 ppm as mentioned in this paper, which is the highest concentration known to date.Abstract:
An electrochemical impedance method to detect concentrations of the local anesthetics Levobupivacaine was implemented and the concentration could be detected to 1 ppm. Electropolymerized pyrrole to polypyrrole (Ppy) and Carbon nanotube (CNT) was fabricated on gold electrodes and used as sensors. Various concentrations of Levobupivacaine from 1 to 500 ppm were prepared in DI water as the test samples.read more
