Fabrication of Highly Effective Electrochemical Bio-sensing Platform Based on Urease-Immobilized Silk Fibroin Scaffold and Aminated Glassy Carbon Electrode |
초록 |
The study involves the successful functionalization of a glassy carbon electrode (GCE) with amine groups (−NH2), to produce aminated GCE. The aminated GCE could be effectively used to detect current changes during the urease-catalyzed decomposition of urea. The silk fibroin (SF) scaffolds were employed to place urease near the surface of the aminated GCE (Urs/SF/aminated GCE). The prepared electrode was employed for electrochemical urea sensing via cyclic voltammetry and amperometry techniques. The fabricated sensing platform displayed rapid detection response and a very high sensitivity with a linear correlation between current and urea concentrations. The analogous sensing responses obtained using replaceable SF scaffold discs (generated and functionalized in the same batch) in the Urs/SF/aminated GCE assure the suitability of the present platform for application in portable urea sensing devices. |
