| Abstract: | A novel nano-SnO_2 electrode was fabricated and applied to the fast counting of E. coli in water. The nano-SnO_2 electrode was used as bioelectrochemical sensor in chronoamperometry to count fastly E. coli with the advantages of quickness, simple operation and high sensitivity. Through assaying the MDA content of E. coli solution treated by electrochemical oxidation, the oxidation mechanism of E. coli at nano- SnO2 electrode was investgated and satisfactory results were obtained. |
