The accurate detection of mismatched base pairs is critical to many DNA hybridization-based applications in basic research and diagnostics. We herein demonstrate that mismatched DNAs on a multispot array can be accurately detected in a multiplexed way by employing the S1 nuclease-based mismatched base pair-specific cleavage system. After the optimization of the reaction condition, mismatched DNAs...
A graphene based biosensor system is presented for performing highly sensitive pathogenic virus detection. A free-standing conductive graphene film was prepared as a novel electrochemical sensor through two steps: synthesis of a graphene oxide (GO) film from GO colloidal suspensions by using a speed vacuum concentrator and thermal annealing process at 900°C with H2/Ar flow to generate a reduced GO...
