Title (EN) METAL NANOPARTICLES OF VARIOUS SIZES AND SHAPES HAVING FUNCTIONAL GROUPS AND METHOD FOR PREPARING THE SAME
(FR) NANOPARTICULES MÉTALLIQUES DE DIFFÉRENTES TAILLES ET FORMES AYANT DES GROUPES FONCTIONNELS ET PROCÉDÉ DE PRÉPARATION CORRESPONDANT
Abstract: front page image
(EN)The present invention relates to metal nanoparticles of various sizes and shapes having functional groups on the surface thereof and a method for preparing the same, and more particularly, to metal nanoparticles coated with a poly(vinylpyrrolidone) copolymer having functional groups and a method for preparing the same. According to the present invention, it is possible to readily prepare metal nanoparticles of regular hexahedral, regular octahedral, spherical shapes and the like, having a particle size of 10 to 500 nm, which comprises functional groups such as hydroxyl group, amine group, carboxyl group and the like on the surface thereof so as to be able to connect various organic molecules to biomolecules, without any post treatment of the metal nanoparticles such as surface treatment, substitution and the like.
(FR)La présente invention concerne des nanoparticules de métal de différentes tailles et formes, ayant des groupes fonctionnels sur leurs surfaces et un procédé de préparation correspondant, et plus particulièrement, des nanoparticules de métal revêtues d’un copolymère de poly(vinylpyrrolidone) ayant des groupes fonctionnels et un procédé de préparation correspondant. Selon la présente invention, il est possible de préparer facilement des nanoparticules de métal de formes régulières hexaèdres, octaèdres, sphériques et similaires, ayant une taille de particules de 10 à 500 nm, qui comprennent des groupes fonctionnels comme un groupe hydroxyle, un groupe amine, un groupe carboxyle et similaire sur leur surface, de façon à pouvoir connecter différentes molécules organiques à des biomolécules, sans aucun post-traitement des nanoparticules de métal, tels que le traitement de surface, la substitution et similaire.
