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.
摘要:
A method for successively functionalizing a substrate whose surface is provided with at least two areas (1, 2) made up of different materials, with at least one chemical substrate, characterized in that the functionalization is carried out without masking and consists (a) in functionalizing a first area (1) without masking the second area (2) or possible successive areas by transforming the substrate with the aid of a chemical substance X1, wherein the first area material reactivity is greater with respect to the reactivity of the substance X1 than the reactivity of the other possible successive areas with respect thereto, and (b1) in treating the second area (2) or the other possible successive areas with a chemical substance Y1 for removing reaction products deposited on said areas during the functionalization from the areas of the substance X1 and/or the possible successive areas without damaging the functionalized surface of the first area.

摘要:
A method for bonding two free surfaces, respectively of first and second different substrates, includes a formation step, on the free surface of the first substrate, of a self-assembled mono-molecular layer consisting of a thiol compound of the SH—R—X type, where —R is a carbonaceous chain and —X is a group selected from the group consisting in —H, —OH and —COOH, at least said free surface of the first substrate being formed by a material able to form molecular bonds with the —SH group of the thiol compound. The method also includes preparing the free surface of the second substrate consisting in saturating the free surface of the second substrate with —H groups if —X is a —H group or with —OH groups if —X is selected from the group consisting in —OH and —COOH, and placing the two free surfaces in contact.
