제목 Fabrication of Highly Effective Electrochemical Urea Sensing Platform using Urease-Immobilized Silk Fibroin-based Aminated Glassy Carbon Electrode.
초록 Glassy carbon electrode was successfully functionalized by amine groups (−NH2) to produce aminated glassy carbon electrode (aminated GCE) through electrooxidation of carbamic acid. Urease-functionalized silk-fibroin (SF) was used for the immobilization of urease near the surface of aminated GCE. Electrochemical methods were employed for the urea sensing by utilizing prepared bioelectrode (Urs/SF/aminated GCE). The aminated GCE could be effectively used for the urea sensing by detecting current changes in the decomposition process of urea by urease. The fabricated sensing platform displayed a high sensitivity and linear correlation between current and urea concentrations. From the different silk fibroin discs generated and functionalized in the same batch, achievement of the similar sensing measurements makes the designed platform effective for portable urea sensing devices.
