La simple modificaci?n de los nanotubos de carbono de pared simple impresos con tetrafluorborato de 1-butil-3-metilimidazolio l?quido i?nico permiti? el desarrollo de una metodolog?a r?pida y selectiva para determinar el imidacloprid (IMI). Las caracter?sticas morfol?gicas y conductoras de la superficie modificada se analizaron con microscop?a electr?nica de barrido y espectroscopia de impedancia electroqu?mica. La superficie modificada mostr? una gran actividad hacia la reducci?n de IMI a -1,2 V. Las variables anal?ticas se optimizaron utilizando voltimetr?a de barrido lineal a 0,1 V durante 60 s, obteniendo un l?mite de detecci?n de 0,21 mg L-1 (0.82 ?Mol L -1). Desviaci?n est?ndar relativa con seis diferentes. Los electrodos fueron del 2,6% (n = 5). Finalmente, se estudiaron las posibles fuentes de interferencia y se aplic? el sensor en la determinaci?n de IMI utilizando muestras de miel comercial con recuperaci?n entre 88,0 y 105,0% para IMI.The simple modification of a screen printed single walled carbon nanotubes with ionic liquid 1-butyl-3-metilimidazolium tetrafluorborate allowed the development of a fast and selective methodology to determine imidacloprid (IMI). The morphological and conductive characteristics of the modified surface were analyzed with scanning electron microscopy and electrochemical impedance spectroscopy. The modified surface showed great activity towards the reduction of IMI to -1.2 V. The analytical variables were optimized using linear sweep voltammetry at 0.1 V for 60s, obtaining a limit of detection of 0.21 mg L-1 (0.82 ?Mol L -1). Relative standard deviation with six different electrodes was of 2.6% (n = 5). Finally, the potential interferers were studied and the sensor was applied in the determination of IMI using samples of commercial honey with recovery between 88.0 and 105.0 % for IMI.
