| Abstract |
Aspergillus niger (A. niger), called black mold, is one of the most common fungi. A. niger can cause plant disease in vegetables and fruits such as onions, peanuts, grapes, and many others. We detected A. niger using electrochemical sensor that is based on interdigitated microelectrodes. When micro-sized fungi were located on the micro gap region by antibodies immobilized on the SiO2 surface between electrodes, the redox signal of ferricyanide was decreased due to the hindrance of the electron transport. The decrement of redox signal was influenced by the concentration of fungi. By using this method, it was able to quantify concentration of fungi and the sensor showed remarkable selectivity compared to that of E. coli. |
