SINGLE NANOPARTICLE CONTAINING ORGANIC-INORGANIC COMPOSITE NANOPARTICLE AND METHOD FOR PREPARING THE SAME

摘要

The invention comprises relates to an organic-inorganic composite nanoparticles and methods for their preparation that contain a single nanoparticle, specifically, 1) the thiol group, and a hydrophilic amine to the inorganic nano-particles of the core or core / shell structure protected by a surface active agent preparing hydrophilic nanoparticles through the thiolate (MS) bond between the metal by the addition of these organic materials; 2) preparing the individual dispersed nanoparticles to create a concentration of the hydrophilic nanoparticles prepared in step 1) to less than 2 × 10 ^-6 M and sonicated by a spectroscopic; And 3) in step 2) the individual distributed amide bonding to the nanoparticles and the biopolymer produced by the step of performing under the ultrasonic bath, organic-inorganic complex comprising a single nano-particles in the center nanoparticles and methods for their preparation from It relates. Presence or absence of the present invention based composite nanoparticles is superior particle uniformity, chemical stability, the aqueous phase dispersion, bio-compatible, and has a target orientation is ensured high-efficiency luminescent and light-stable bio-very useful as a material for the image or film coatings for It can be used. ; Quantum dots, nanoparticles, inorganic nanoparticles composites, bio-imaging and inorganic nanocomposite films
