- A method for the preparation of a nanocolloidal solution of rhenium sulfide is proposed. It includes the following stages: interaction of ammonium perrhenate and sodium thiosulfate in an aqueous solution of gelatin in an acidic medium with heating to 70–80°C; neutralization to pH 7.0; dialysis against saline; desalination and concentrating by ultrafiltration. The resulting colloidal solution contains 85% of particles with an optimal size of 80–100 nm and can be used as a diagnostic tool for lymphoscintigraphy of sentinel lymph nodes in patients with cancer and other diseases.
