A biosensor method for the determination of triazine pesticides based on an inhibition organic phase enzyme electrode (OPEE) is described. The OPEE was developed using a tyrosinase biosensor assembled in the version operating in organic phase and used to determine triazine pesticides by exploiting their power to inhibit the tyrosinase enzyme. The results show the full validity of the method, which has also been optimized by comparing two different operating procedures. Lastly, the tyrosinase OPEE was also used to test triazine recovery from common vegetal samples, obtaining recoveries always >90%. (c) 2005 Elsevier B.V. All rights reserved.

Abstract
A biosensor method for the determination of triazine pesticides based on an inhibition organic phase enzyme electrode (OPEE) is described. The OPEE was developed using a tyrosinase biosensor assembled in the version operating in organic phase and used to determine triazine pesticides by exploiting their power to inhibit the tyrosinase enzyme. The results show the full validity of the method, which has also been optimized by comparing two different operating procedures. Lastly, the tyrosinase OPEE was also used to test triazine recovery from common vegetal samples, obtaining recoveries always >90%. (c) 2005 Elsevier B.V.
