Label-free detection of telomerase activity in HeLa cells using electrochemical impedance spectroscopy

Abstract

A simple assay based on electrochemical impedance spectroscopy (EIS) for detection of telomerase activity is developed, and it is demonstrated that the label-free EIS method is capable of detecting the telomerase activity in HeLa cells with a detection limit of 1000 HeLa cells without using any amplification technique.
