Novel estradiol sensors based on carbon nanotube multilayer modified gold hair microelectrodes

摘要

Multi-walled carbon nanotube multilayers were modified onto a newly proposed gold hair microelectrode via a simple layer-by-layer assembling method.The resulting electrode showed a sensitive oxidation response to estradiol with detection limit as low as 1.0×10^(-8) mol/L,foreseeing a promising approach to the fabrication of high-sensitive microsensors.
