    Abstract:  粒子サイズがよく揃い粒径が精密に制御されたナノサイズの無機物粒子が有機溶媒中での合成によって得られるようになったものの、その無機物粒子には長鎖の脂肪酸が粒子表面に吸着しているため極性溶媒中での分散が阻害されており、しかもこの表面被覆を置換して極性溶媒中で分散するナノサイズの無機物粒子を得ることが困難であった。脂肪酸で被覆された無機物粒子が分散している非極性溶媒中に、チオリンゴ酸などの一時被覆物質を添加して粒子の脂肪酸被覆をまずこの一時被覆物質被覆で置換し、次にこの一時被覆物質で被覆された無機物粒子を極性溶媒に分散し、この分散液にクエン酸などの極性溶媒分散性被覆物質を添加し、無機物粒子を被覆している一時被覆物質被覆をこの極性溶媒分散性被覆物質で置換することによって、脂肪酸で被覆された無機物粒子から極性溶媒中で分散するさまざまな表面被覆無機物粒子を得ることができるようになった。

    Abstract: Atherosclerosis is an inflammatory disease of the arterial walls and represents a significant health problem in developed nations. Described is a targeted Magnetic Resonance Imaging (MRI) contrast agent for in vivo imaging of early stage atherosclerosis. Early plaque development is characterized by the influx of macrophages, which express a class of surface receptors known collectively as the scavenger receptors (SR). The macrophage scavenger receptor class A (SRA) is highly expressed during early atherosclerosis. The macrophage SRA therefore presents itself as an ideal target for labeling of lesion formation. By coupling a known ligand for the scavenger receptor, dextran sulfate, to a MRI contrast agent, early plaque formation can be detected in vivo . Targeted MR contrast agents offer a unique opportunity to visualize early plaque development in vivo with high sensitivity and resolution, allowing or early diagnosis and treatment of atherosclerosis.

    Abstract: Magnetically responsive particles and to their use in systems in which the separation of certain molecules from the surrounding medium is necessary or desirable are disclosed. The magnetically responsive particles consist of a metal, metal oxide or metal alloy core, coated with an organo-metallic polymer having attached thereto an organic functionality to which a variety of organic and/or biological molecules can be coupled. The particles can be dispersed in aqueous media without rapid gravitational settling and conveniently reclaimed from the media using a magnetic field. The magnetically responsive particles of the invention may be coupled to biological or organic molecules with affinity for, or the ability to absorb, or which interact with certain other biological or organic molecules. Particles so coupled may be used in a variety of in vitro or in vivo systems involving separations steps or the directed movement of coupled molecules to particular sites, including immunological assays, other biological assays, biochemical or enzymatic reactions, affinity chromatographic purification, cell sorting and diagnostic and therapeutic uses.
