摘要 |
<p>A biosensor comprises a sensor matrix where sensor cells (10) are arrayed in a matrix, a row driver (13) for supplying a predetermined voltage signal to sensor cells arrayed in the row direction of the matrix, and a column driver (12) for supplying a predetermined voltage signal to sensor cells arrayed in the column direction of the matrix. Each of the sensor cells (10) is provided with a capacitive element (Cs) composed of a pair of opposed electrodes where a probe DNA selectively reactive with a target DNA is fixed to the electrode surface, a transistor (Tr2) for varying the value of the current outputted from a drain terminal in response to the variation of the capacitance of the capacitive element (Cs) caused by DNA hybridization, and a switching element (Tr1) for supplying a voltage signal supplied from the column driver (12) to the current input terminal of the transistor (Tr1).</p> |
