Description
In clinical analysis, the use of contrast medium is of great importance because it allows the visualization of specific structures in cells and tissues, facilitating the detection of anomalies in the body and contributing to more precise and early diagnoses (1). However, current contrast medium methods have certain disadvantages, so developing new methods is an important area of research. In this work, magnetite nanoparticles doped with neodymium (Nd) and ytterbium (Yb) were synthesized using the iron salt co-precipitation method. Subsequently, they were coated with silicon dioxide (SiO2) and Nd, improving their luminescence and biocompatibility. The core-shell nanoparticles were physicochemically characterized, determining the crystalline structure of their core with an approximate size of 15nm, as well as their luminescence with absorption and emission at 656nm and 990nm, respectively. The results show these nanoparticles are possible candidates for contrast medium in biomedical applications.
