Impedance based nanocrystalline silicon oxide immunosensor electronic tongue for ultrasensitive and low cost multiple food toxin detection

Nanocrystalline silicon oxide (nc-SiO2) immunosensor has been reported earlier to detect a single food toxin from a mixture of other toxins with a detection limit of 0.1 fg/ml by impedance spectroscopy method. But there are no reports of detecting multiple food toxins in complex mixtures using these sensors. Usually, detection of `n' number of food toxins… (More)
