A new paper entitled "Electrochemical Biosensor Based on Optimized Biocomposite for Organophosphorus and Carbamates Pesticides Detection" by R. Montes, F. Cespedes, D. Gabriel and M. Baeza has been published in Journal of Nanomaterials 2018, ID 7093606, 13 pages.
An important feature for the development of more sensitive amperometric biosensors for pesticide detection is the optimization of the biocomposite composition in order to guarantee the best final electroanalytical properties of response.
The main goal of this study is the application of systematic strategies of characterization to optimize the biocomposite composition based on graphite-epoxy that incorporates acetylcholinesterase (AChE) on the matrix. These characterization techniques (Electrochemical Impedance Spectroscopy and Cyclic Voltammetry) pretend to optimize the conducting particle distribution on the electrode surface as function of the carbon and biological loading. Optimized biosensors guarantee more sensitive pesticides biosensors regarding detection limits.
This work has been done in collaboration among members of the GENOCOV researcher group and the Chemistry Department at UAB and was supported by the Spanish Government with a grant “Retos de la Sociedad 2015” reference CTQ2015-69802-C2-1-R.
