A method for producing a graphene oxide-based compound for an air electrode of a metal-air battery. A nitrogen and sulfur-based organic compound is added to an aqueous suspension of a graphene oxide. The water of the suspension is evaporated in order to obtain a powder. This powder is heated under an inert atmosphere in order to sublime the organic compound and stimulate the incorporation of nitrogen from the organic compound into the graphitic sites of the graphene oxide. The nitrogen and sulfur-doped graphene oxide is added to a second aqueous suspension comprising a cobalt nitrate-based compound. This second suspension is heated in order to form nanoparticles of cobalt oxide at the surface of at least one nitrogen and sulfur-doped graphene oxide sheet.

The invention relates to using persistent luminescence nanoparticles, functionalised if necessary, in the form of an diagnosis agent for an in vivo optical imaging. Said nanoparticles are preferably consist of a compound selected from a group comprising (1) silicates, aluminates, aluminosilicates, germanates, titanates, oxysulphides, phosphates and vanadates, wherein said compounds contain at least one type of metal oxide, (2) the sulphides comprise at least one metal ion selected from zinc, strontium and calcium, and (3) metal oxides, wherein said compounds is doped with at least one rare earth ion, and possibly with at least one transition metal ion. In a preferred embodiment, the diagnosis agent is used for an organism vascularization imaging. A method and kit for detecting or quantifying in vitro a substance of biological or chemical interest in a sample by using said pre-functionalised nanoparticles are also disclosed.
