Potentiometric stripping analysis at pretreated carbon paste electrodes enables highly sensitive measurement of nanogram quantities of DNA.
Potentiometric stripping analysis is employed for highly sensitive measurements of single‐stranded DNA at carbon paste electrodes. Electrochemical (oxidative) pretreatment is used to condition the carbon paste surface prior to the accumulation process. The low background response of the potentiometric stripping mode offers convenient quantitation of low nanogram quantities of DNA. Experimental variables of the pretreatment and measurement procedures are explored and optimized. Results are also reported for the quantitation of nanogram levels of the long terminal repeat (LTR) from the human leukemia virus and for the stripping operation of microfabricated screen‐printed electrodes.
