Yue, Rong; Lu, Qing; Zhou, Yikai published the artcile< A novel nitrite biosensor based on single-layer graphene nanoplatelet-protein composite film>, Category: esters-buliding-blocks, the main research area is nitrite biosensor single layer graphene nanoplatelet protein composite film.
A novel nitrite biosensor was developed through a sensing platform consisted of single-layer graphene nanoplatelet (SLGnP)-protein composite film. SLGnP with the virtues of excellent biocompatibility, conductivity and high sensitivity to the local perturbations can provide a biocompatible microenvironment for protein immobilization and a suitable electron transfer distance between electroactive centers of heme protein and electrode surface. A pair of well-defined and quasi-reversible cyclic voltammetric peaks that reflected the direct electrochem. for ferric/ferrous couple of myoglobin (Mb) was achieved at the composite film modified electrode. Field emission SEM (FESEM) and UV visible spectra (UV-vis) were utilized to characterize the composite film. The results demonstrated that the morphol. of the composite film was unique and the protein in the composite film retained its secondary structure similar to the native state. The composite film also displayed excellent electrocatalytic ability for the reduction of nitric oxide, which was applied to determine nitrite indirectly. It exhibited good electrochem. response to nitrite with a linear range from 0.05 to 2.5 mM and a detection limit of 0.01 mM.
