The objective of this work was to investigate the possibility of using carbon screen printed electrodes (SPE) in combination with the use of N2a cells for the direct voltammetric determination of 5 neonicotinoids (imidacloprid, clothianidin, thiacloprid, acetamiprid and thiamethoxam) and 3 tetronic acid amide insecticides (spiromesifen, spirodiclofen and spirotetramat). The insecticide cytotoxicity in N2a cells was determined after 30 min treatment with concentrations 3, 10, 30 and 100 μM by the propidium iodide (PI) uptake assay. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were performed to compare signals from plain carbon screen printed electrodes and from N2a cells. 1 pp. LOMv1.0 creator LOMv1.0 Project Final Beneficiary LOMv1.0 Project Executing Organisation Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Acid Amides Cytotoxicity N2a Cells Screen printed electrodes 538296 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/2728/2/2728_Poster%20Biomep.pdf URI http://hdl.handle.net/10795/2728 LOMv1.0creator 2016-04-19T08:48:34Z LOMv1.0validator 2016-04-19T08:48:34Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
