Cancer diagnosis and treatment: "4-in-1" nanoparticles

The researchers connected fluorescent dye, RNA fragments and peptide fragments to iron oxide nanoparticles. The task of peptides is to identify tumor cells, RNA fragments suppress the work of a number of genes characteristic of cancer cells, killing them. Magnetic iron oxide nanoparticles play the role of contrast for MRI, and fluorescent dye allows you to observe cancer cells using microscopy.
