| abstract |
An electrochemical biosensor based on an enzyme acetylcholinesterase (ache) from any source, consisting of a sensor containing three working electrodes, made of graphite containing the tcnq mediator, and in which the enzyme paste is applied is described herein; one reference (ag / agcl), and one auxiliary (graphite). The biosensor operates at a relatively low working potential (100 mv), has high measurement accuracy, and high sensitivity for detecting microcystin-lr in liquid or pasty samples. |
