Different electrochemical pa-rameters of MBD were obtained at MWCNT-GCE by cyclic voltammetry. Also the electrocatalytic behavior of LD was investigated at the MBD-MWNT-GCE by cyclic voltammetry, chronoamperometry and differen-tial pulse voltammetry. Using the electrocatalysis of LD V in phosphate buffer solution pH 7.0 on this modified electrode it is possible to obtain a linear calibration curve from 5.0¡Á10 7 to 9.0¡Á10 4 M and a de-tection limit of 0.37 ¦ÌM for LD by differential pulse voltammetry. The electrode was successfully applied for determination of LD in real sample. %K Nanomaterials %K Nanobiotechnology %K Pharmaceutics %K Biochemical engineering %K Diagnostics and treatment methods %U http://nap.sumdu.edu.ua/index.php/nap/nap2012/paper/view/390
