摘要:
The invention relates to an electropolymerisable monomer which is intended to be polymerised in aqueous solution, comprising a single electropolymerisable unit and an electron donor group. The invention is characterised in that it also comprises at least one arm that can be ionised in aqueous solution. The invention also relates to the polymerisation method, the electroactive probe thus obtained and the method of detecting a target ligand in a biological sample.
摘要:
The present invention relates to a thiol compound suitable for forming a chain of oligomers that can be grafted to an oligonucleotide. The invention also relates to an oligonucleotide grafted by such a compound, thus having one or more thiol functions, suitable for being immobilized on a gold surface or on a grafted surface.
摘要:
The present invention concerns a modified oligonucleotide having two or a plurality of thiol functions, capable of being immobilised on a gold surface or on a grafted surface, in particular a surface comprising at least one carbon-carbon double bond or one carbon-carbon triple bond or halogen acetamide functions, preferably maleimide or acrylamide functions. The invention also concerns a method for detecting a nucleic acid in a biological sample comprising a step of detecting hybridisation between a modified oligonucleotide and an amplified target nucleic acid from the biological sample. The invention more specifically concerns a method for detecting genotyping or sequencing of a pathogenic organism, preferably a virus.
摘要:
The invention relates to a material formed by a porous support onto which functionalised nanoparticles are covalently grafted. The material is characterised in that: at least part of the covalently grafted nanoparticles are housed inside surface pores of the support; and the support is based on silica and takes the form of porous particles of heterogeneous shape and size, the particle size being greater than 1 μm and, preferably, between 5 and 200 μm. The invention also relates to a method for growing oligonucleotides or peptides, characterised in that: the oligonucleotides or peptides are grown on a material formed by a porous support onto which functionalised nanoparticles are covalently grafted, and at least part of the covalently grafted nanoparticles are housed inside surface pores of the support.
