摘要
Infectious of hepatitis C viruses(HCVs)lead to hepatic fibrosis,cirrhosis even hepatoma.Developing rapid and sensitive diagnostic method for HCV is of great importance.Based on the host-and-guest interaction between cucurbit[7]uril(CB[7])and methylene blue(MB),a CB[7]-graphene nano-composite(CB[7]-N3-GO)is raised for the electrochemical detection of HCV DNA.The method is able to linearly detect the HCV nucleic acid in the range of 0.2—10 nmol/L with detection limit as low as 160.4 pmol/L.The proposed detection strategy is able to discriminate the lb and 6k subtypes of HCV and has a prospective potential in the blood screen for HCV in clinical diagnosis.
