In this paper a novel nanocomposite material prepared by Co 3 O 4 nanorods (nano-Co 3 O 4 ), graphene (GR) and chitosan (CTS) was fabricated and further modified on carbon ionic liquid electrode (CILE), which was used as the substrate electrode to construct a new electrochemical DNA biosensor. The single-stranded DNA (ssDNA) probe was immobilized on the CTS–Co 3...
A novel biocompatible sensing strategy based on a graphene (GR), ionic liquid (IL) 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIMBF 4 ) and chitosan (CTS) composite film for the immobilization of myoglobin (Mb) was adopted in this paper. The UV–vis and FT-IR spectroscopic results demonstrate that the Mb in the composite film maintained its native structure. The direct electron transfer...
In this paper a Fe 3 O 4 microsphere, graphene (GR) and chitosan (CTS) nanocomposite material modified carbon ionic liquid electrode (CILE) was used as the platform for the construction of a new electrochemical DNA biosensor. The single-stranded DNA (ssDNA) probe was immobilized directly on the surface of the CTS/Fe 3 O 4 –GR/CILE, which could hybridize with the target...
