Abstract
The invention relates to a detection device of small size, allowing direct in situ detection of particles with no labelling, enabling the particles to be rapidly analysed, and having both a specificity and a sensitivity that are at least equivalent to the existing devices. In one embodiment, the invention provides a device having a nanowire, intended for interacting with the particles of interest, which is suspended between two anchors that define a source and a drain, the source and the drain are configured to be connected to an AC voltage generator and to a DC voltage generator, respectively, in order to generate a first input signal; an excitation electrode, placed laterally facing the nanowire and configured to be connected to an AC voltage generator, in order to generate a second input signal; and a measurement electrode placed opposite the excitation electrode relative to the nanowire and generating a single output signal representative of the particles of interest.
