确实有文章报道ssDNA信号更强,但是我看到不同文献有不同的解释,这是怎么回事?
(1)Highly sensitive electrochemical impedance spectroscopic detection of DNA hybridization based on Aunano–CNT/PANnano films,Talanta 77 (2009) 1021–1026
(2)Application of chitosan/Fe3O4 microsphere–graphene composite modified carbon ionic liquid electrode for the electrochemical detection of the PCR product of soybean Lectin gene sequence,Talanta 87 (2011) 106–112
