METHOD OF DETERMINING A SENSITIVITY OF A BIOSENSOR ARRANGEMENT, AND BIOSENSOR SENSITIVITY DETERMINING SYSTEM |
摘要 |
According to an embodiment of the present invention, a method of determining or adjusting the sensitivity of a biosensor arrangement comprising at least one field effect biosensor is provided, each of the at least one field effect biosensor comprising: a semiconductor substrate comprising a source region, a drain region and a channel region disposed between the source region and the drain region; a gate isolation layer covering the channel region; and a reference electrode disposed over the gate isolation layer such that a electrolytic solution to be sensed can be provided between the reference electrode and the gate isolation layer. The method comprises the following processes carried out for each field effect biosensor: providing an electrolytic solution between the reference electrode and the gate isolation layer; applying a source/drain voltage between the source region and the drain region; varying a reference voltage supplied to the reference electrode over a voltage range; measuring a resulting drain current while varying the reference voltage in order to obtain a corresponding drain current function; and determining the sensitivity of the field effect biosensor based on the reference voltage supplied to the reference electrode and the corresponding drain current function.
