A Facile and Novel Route to ~(99m)Tc-labeled Antimony Sulfide Nanocolloid

摘要

~(99m)Tc-labeled antimony sulfide nanocolloid was prepared by a new labeling method that involves room temperature recon-stitution with Na~(99m)TcO_4.Transmission electron microscope showed that the mean particle size was estimated to be mostly 7-15 nm.The labeling yield of ~(99m)Tc-Sb_2S_3 was more than 99%.The stability of the labeled product was studied at room temperature and it was found to be excellent.
