A gravimetric detector including a nanoelectronic structure including: a fixed part, at least one part suspended from the fixed part, an excitation device to vibrate the suspended part relative to the fixed part, a detector to detect variations in vibration of the suspended part, and a porous functionalization layer at least partially covering the suspended part, porosity of the functionalization layer being between 3% and 50%.

Gravimetric gas sensor having a lowered detection limit

The invention relates to the use of disubstituted alkynes for the functionalisation of the surface of a substrate consisting of a semi-conductor material, with molecules of interest. According to the invention, a compound of formula A-(E1)-F1 is used, wherein A is a linear or cyclic disubstituted alkyne, E1 is an alkyl chain and n2 is 0 or 1, and F1 is a reactive group that can react with the reactive group F2 of a compound of formula F2-(E2)-X wherein E2 is an alkyl chain and X is a group having properties of interest. The invention is especially applicable to the field of molecular biology or biotechnology.

Method for surface functionalization by disubstituted alkynes

The invention relates to compounds comprising a cycloalkyne or heterocycloalkyne group and a redox group. Said compounds are of general formula (I) wherein Z is a cycloalkyne or heterocycloalkyne with at least 8 links, optionally substituted by a halogen atom or a linear or branched C1 to C5 alkyl, A is an organic structure having oxidation-reduction properties, and B is an organic link between the cycloalkyne or heterocycloalkyne cycle and the organic structure A. The invention is especially applicable to the field of molecular electronics.
