Carbon nanoparticle suspension injection-fe, preparation method, application and use method

Abstract

Carbon nanoparticle suspension injection-Fe, a preparation method, an application and a use method. The carbon nanoparticle suspension injection-Fe includes carbon nanoparticle suspension injection and ferrous sulfate, where a concentration of the carbon nanoparticle suspension injection is 20-100 mg/mL, a concentration of ferrous ions in the carbon nanoparticle suspension injection-Fe is 0.5-60 mg/mL, and a particle size of carbon nanoparticles in the carbon nanoparticle suspension injection-Fe is 90-250 nm, and a pH value is 2.8-6.0. The carbon nanoparticle suspension injection-Fe serves as a developing agent after being injected into a tumor to show distribution of the carbon nanoparticle suspension injection-Fe and retention in the tumor on a magnetic resonance image.
