The present disclosure relates to a method to produce an oxygen evolution reaction electrode catalyst assembly comprising a dendritic nickel foam. The method is remarkable in that it comprises the steps of (a) providing a dendritic nickel foam material; (b) etching the dendritic nickel foam material by placing it in a etch solution being an acidic aqueous solution or an aqueous solution of metal chloride and recovering an etched dendritic nickel foam with nickel dendrites showing a chimney-like structure.

Functionalized substrate and uses thereof

The invention concerns a method for analyzing biological targets of DNA or RNA type, which comprises the following steps:

Method and support for biological analysis using oligonucleotides comprising a marker capable of enzymatic activation

This invention relates to an analytical support containing a plurality of oligonucleotides fixed on this support, where each of the nucleotides is marked by a fluorescent compound that presents a variation of fluorescence on the hybridization of each marked oligonucleotide with at complementary oligonucleotide. This support makes it possible to carry out an analysis of biological targets by measuring the variation of fluorescence in order to determine the hybridization of the targets with the oligonucleotides of the support.
