  • Abstract Using the property of carbon nanotubes (CNTs) to design the biosensor that be more stable and sensitive. Surface treated CNTs by grafting on inorganic surface for single strand DNA immobilization.
    In this study, we use two different systems to test. The ss-DNA can be convalently attached to CNTs by way of activated in acid oxidation conditions then PEI and GA chemistry immobilization. We can check the substance immobilization by the frequency shift using the QCM to detect.We can use the same grafting method to the interdigital electrode. When the DNA probe immobilization and hybridization, the resistance will be decrease. As a result, the concentrations of Vibrio parahaemolyticus change from 58.4 ng/ml to 1870 ng/ml, the resistance variate from 1.52 Ω to 3.04 Ω.
