Abstract
The device () 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 () in which is integrated an MOS device having a floating gate () a first portion (a) of which extends in facing relation to a recess () formed in a surface of the chip () and accessible from outside the chip () and operable to retain an electrical charge (Qs) to be measured bound to it. A second portion (b) of the gate () of the MOS device is coupled to a control electrode, () of the chip () by means of a capacitor () of predetermined value within the chip ().
