  • Title: A label-free amplified fluorescence DNA detection based on isothermal circular strand-displacement polymerization reaction and graphene oxide.
    Author: Li Z, Zhu W, Zhang J, Jiang J, Shen G, Yu R.
    Journal: Analyst; 2013 Jul 07; 138(13):3616-20. PubMed ID: 23671905.
    Abstract:
    A label-free fluorescent DNA biosensor has been presented based on isothermal circular strand-displacement polymerization reaction (ICSDPR) combined with graphene oxide (GO) binding. The proposed method is simple and cost-effective with a low detection limit of 4 pM, which compares favorably with other GO-based homogenous DNA detection methods.
