| abstract |
The present invention relates to a multiwell electrode-based biosensor, which, by using amperometry, can have a reduced size compared to existing biosensors that use impedance measurement and, by incorporating immunoassay methods, shows sensitivity to the level of fg/ml and thus can effectively detect a target protein comprised, in blood, in an extremely small amount. Probes which are different from one another are comprised in multiple wells and thus various target proteins can simultaneously be detected by means of a single procedure. |
