摘要

Silica-coated Agl nanoparticles were prepared with a Stober method, which was performed with 2.3×10~(-5) M 3-mercaptopropyltrimethoxysilane, 11 M water, 0.01 M dimethylamine and 0.01 M tetraethyl orthosilicate in the presence of 5×10~(-)4 M Agl nanoparticles that were prepared from silver perchlorate and potassium iodide. The particles had an Agl core size of ca. 15 nm and a silica shell thickness of ca. 20 nm. The particle colloid that was concentrated up to an Agl concentration as high as 0.4 M with centrifugation was colloidally stable in saline, and exhibited properties of X-ray absorption and X-ray contrasting comparable to a commercial X-ray contrast agent.
