Title (EN) MICROPARTICLE HAVING NEEDLE-LIKE SURFACE AND PROCESS FOR PRODUCTION THEREOF
(FR) MICROPARTICULE À SURFACE SEMBLABLE À DES AIGUILLES ET PROCÉDÉ DE PRODUCTION CORRESPONDANT
(JA) 針状表面微粒子及びその製造方法
Abstract:
(EN) Disclosed are: an organic-inorganic composite microparticle containing a metal complex, which has multiple needle-like structures on the surface and includes the metal complex therein; and a process for producing the microparticle in a simple manner. By using a metal complex composed of a polymer having a linear polyethyleneimine skeleton and a metal ion, the formation of a composite microparticle can be induced which has the metal complex in silica and has a microneedle-like surface, thus a microparticle having a needle-like surface in which nano-sized multiple needle-like structures are formed on the surface. The needle-like structure and the spatial structure of the finished microparticle can be controlled by varying the species of the metal ion and the types of the substrate medium for the metal complex.
(FR) L’invention concerne une microparticule composite organique-inorganique contenant un complexe métallique qui comprend sur sa surface de nombreuses structures semblables à des aiguilles y compris le complexe métallique mentionné, ainsi qu’un procédé aisé de production de cette microparticule. En utilisant un complexe métallique composé d’un polymère ayant un squelette polyéthylèneimine linéaire et un ion métallique, la formation d’une microparticule composite qui contient le complexe métallique en silice et présente une surface semblable à des micro-aiguilles, peut être induite, ce qui donnera une microparticule à surface semblable à des aiguilles dans laquelle de nombreuses structures semblables à des nano-aiguilles sont formées à la surface. Il est possible de contrôler la structure semblable à des aiguilles et la structure spatiale de la microparticule terminée en variant le type d'ion métallique et les types de substrat du complexe métallique.
(JA)  本発明は、多数の針状構造を表面に有する金属錯体含有する金属錯含有有機無機複合体微粒子、および該粒子の簡便な製造方法を提供する。直鎖状ポリエチレンイミン骨格を有するポリマーと金属イオンとからなる金属錯体により、該金属錯体をシリカ内部に含有する微細針状表面の複合微粒子が誘導され、微粒子の表面にナノ次元の針状構造を多数有する針状表面微粒子を実現できる。得られる針状表面微粒子の針状構造および粒子の空間構造は、金属イオン種や金属錯体支持媒体を変化させることで制御できる。
