In this study, for the first time a model electrochemical kit was constructed for the detection of a functional polymorphism in catechol‐ O ‐methyl transferase (COMT) gene which is important for diagnosis of neuropsychiatric disorders as Alzheimer disease. The disposable pencil graphite electrode (PGE) is designed as a “kit” and the probe DNA covered PGE can detect single nucleotide polymorphisms (SNPs) from real samples based on the guanine oxidation signal even after 5 months of kit preparation (150 days durability).The detection limit ( S/N =3) of the biosensor was calculated as 1.18 pmol of synthetic target sequence and 6.09×10 5 molecules of real samples in 30 min detection time.
