Disclosed is a method for preparing a hybrid organic/inorganic composition including inorganic nanoparticles functionalized by at least one molecule chosen from photoluminescent charged organic molecules, the method including bringing into contact, in a single-phase solvent medium, at least one photoluminescent charged organic molecule and non-swelling phyllosilicate nanoparticles having a thickness of 1 nm to 100 nm, and a larger dimension of 10 nm to 10 μm. Also disclosed are hybrid photoluminescent nanoparticles compositions obtained by this method.
Method for the preparation of an organic/inorganic hybrid composition comprising mineral nanoparticles functionalized by at least one molecule chosen from photoluminescent charged organic molecules, this method comprising at least bringing into contact, in a monophasic solvent medium, of at least one photoluminescent charged organic molecule and non-swelling phyllosilicate nanoparticles having a thickness of 1 nm to 100 nm, and a larger dimension of 10 nm to 10 μm.
A method for extracting from an environment a photoluminescent charged organic molecule, comprising applying an effective amount of non-swelling phyllosilicate nanoparticles, having a thickness of 1 nm to 100 nm, and a larger dimension of 10 nm to 10 μm, thereby forming a hybrid organic/inorganic composition by adsorption of said photoluminescent charged organic molecule to said non-swelling phyllosilicate nanoparticles, wherein when said environment is a biological tissue, the biological tissue is isolated or cultivated.
A method for neutralizing a photoluminescent charged organic molecule absorbed by an individual or by an animal, comprising causing said individual or animal to absorb non-swelling phyllosilicate nanoparticles, having a thickness of 1 nm to 100 nm, and a larger dimension of 10 nm to 10 μm, thereby forming a hybrid organic/inorganic composition by adsorption of said photoluminescent charged organic molecule to said non-swelling phyllosilicate nanoparticles.
