Abstract

The invention discloses functionalized nano particles with diamino triazine functional groups as well as a preparation and an application method of the nano particles. The average particle size of the functionalized nano particles is 10-1000nm; and the functionalized nano particles of which the surface have the diamino triazine functional groups are obtained according to the following method: based on 2-vinyl-4, 6-diamino-1, 3, 5-triazine as a functional monomer, initiating the homopolymerization of the functional monomer or the copolymerization of the functional monomer and other auxiliary monomers by a free radical initiator according to the principle of the free radical polymerization. The functionalized nano particles disclosed the invention have large surface area and volume ratio, controllable particle size, good latex stability and good compatibility with a biological test sample by using water as a dispersing agent, and can be used directly. A strong hydrogen bond bonding is formed in aqueous solution by the diamino triazine functional groups on the surface of the functionalized nano particles and uric acid, nucleic acid base, nucleotide, nucleoside, desoxyribonucleic acid, protein and the like, so that strong selective adsorption is generated, and the functionalized nano particles can be applied to the fields such as drug delivery, chemical catalysis, material separation and purification, sensor technology, and analysis technology.
