| 英文摘要 | we report a hydrothermal method to prepare reduced graphene oxide (rgo)-based hydrogel (gel(rgonr)), using neutral red (nr) to mediate the assembly of rgo sheets and tune the pore size of gel(rgonr). a series of techniques including scanning electron microscopy (sem), x-ray photoelectron spectroscopy (xps), x-ray diffraction (xrd), raman spectroscopy and bet were employed to characterize the physicochemical properties of gel(rgonr). a large pore size of up to 20 mu m and interconnected porous structure of gel(rgonr) were obtained. gel(rgonr) was used as a support for immobilizing microbe (denoted as gel(rgonr-m)), which showed similar to 3.3 times more load mass of microbe than commonly used supports (i.e., activated carbon and carbon fiber felt) and 2.5 times higher biodegradation efficiency (be) than carbon fiber felt. further use of gel(rgonr-m) as a biocatalyst for establishing a bod biosensor exhibits a linear range of 2-64 mg o l-1 and a detection limit 0.4 mg o l-1 for glucose-glutamic acid (gga). moreover, our proposed bod detection strategy shows a long-term viability over one year and stability up to 2 months with a relative standard deviation of 2.1%. our results demonstrated the great potential of employing gel(rgonr) as a microbe-immobilization support for biosensor development.
