[object Object]

The present invention relates to a novel bilirubin oxidase from, to the method of preparation thereof as well as use thereof notably for assay of bilirubin and for the application of enzymatic biofuel cells.

The present invention relates to mutants of theglucose oxidase (GOx) enzyme which are of use for assaying glucose and to the development in particular of glucose electrodes and of biocells which use glucose as fuel.

A porous electrochemical electrode is made up of a solid cellular material provided in the form of a semi-graphitized carbon monolith comprising a hierarchized porous network free of mesopores and including macropores with a mean dimension dof 1 &#x3bc;m to 100 &#x3bc;m, and micropores with a mean dimension dof 0.5 nm to 2 nm, said macropores and micropores being interconnected. In said electrode, the macropores contain at least one electroactive species in direct contact with the semi-graphitized carbon that makes up the surface of the macropores. The invention also relates to a method for preparing such an electrode as well as to the use thereof as a biosensor or for manufacturing a biopile.

Enzymatic modifications of a cellular monolithic carbon and uses thereof

The present invention relates to novel mutants of PQQ s-GDH containing an amino acid substitution in position 428 of the protein sequence of the wild type PQQ s-GDH of(SEQ.ID. NO:2). The invention also relates to the use of said PQQ s-GDH mutants for the development of glucose electrodes of interest in the assay of glucose, in particular of blood glucose in diabetic subjects, and for implementing biofuel cells that utilize glucose as fuel.
