An insight into the hybridization mechanism of hairpin DNA physically immobilized on chemically modified graphenes
There is an emerging interest in developing electrochemical DNA biosensors which rely on label-free protocols for the detection of DNA hybridization and polymorphism. Lately, many of them have been using DNA probes which ...
Thrombin aptasensing with inherently electroactive graphene oxide nanoplatelets as labels
Graphene and its associated materials are commonly used as the transducing platform in biosensing. We propose a different approach for the application of graphene in biosensing. Here, we utilized graphene oxide nanoplatelets ...
Biorecognition on graphene : physical, covalent, and affinity immobilization methods exhibiting dramatic differences
The preparation of biorecognition layers on the surface of a sensing platform is a very crucial step for the development of sensitive and selective biosensors. Different protocols have been used thus far for the immobilization ...
