Abstract

In this study we report the DNA biosensor based on multi-walled carbon nanotubes (MWNT) and chitosan (CHIT) composite used as an interface at the screen printed carbon electrode (SPCPE). The surfaces of the DNA modified screen printed carbon paste electrodes were studied by cyclic voltammetry and EVLS and also by using the microscope techniques.

Abstract (in Czech)

Tato práce pojednává o vývoji DNA biosenzoru založeném na uhlíkových nanotrubičkách a chitosanovém kompozitu použitém jako mezifází na tištěných uhlíkových elektrodách. Povrchy takto modifikovaných elektrod byly studovány elektrochemicky (CV, EVLS) a pomocí mikroskopu.
