A FIELD-EFFECT DEVICE FOR THE DETECTION OF SMALL QUANTITIES OF ELECTRIC CHARGE, SUCH AS THOSE GENERATED IN BIO-MOLECULAR PROCESSES, BOUND IN THE VICINITY OF THE SURFACE |
摘要 |
<p>The device (1) allows the detection of small quantities of electrical charge (Qs) utilised for recognition of the gybridisation process of a single strand of DNA. It comprises a chip (2) in which is integrated an MOS device having a floating gate (7) a first portion (7a) of which extends in facing relation to a recess (8) formed in a surface of the chip (2) and accessible from outside the chip (2) and operable to retain an electrical charge (Qs) to be measured bound to it. A second portion (7b) of the gate (7) of the MOS device is coupled to a control electrode, (10) of the chip (2) by means of a capacitor (12) of predetermined value within the chip (2).</p> |
