Abstract
The invention relates to new, inexpensive electropolymers capable of light-induced grafting, onto which specific identification probes can be easily grafted and having optimum capacity for interaction with the target analytes (DNA/DNAc, PNA/PNAc, enzyme/substrate/Antibody/Antigen).These electropolymers capable of light-induced grafting are, for example, poly(pyrrole-benzophenone). Benzophenone forms sites for light-induced grafting.The invention also covers the mono and oligomers which make up these novel electropolymers capable of light-induced grafting.Another object of the invention is the process for their manufacture, as well as electronic biosensors containing these electropolymers capable of being grafted and/or grafted by probes for the analysis of biomolecules.
