Gold nanoparticles for theranostic treatment of cancer

The chemical stability, low toxicity, and relative simplicity of methods for the synthesis and modification of gold nanoparticles open up wide possibilities for their use as theranostic agents for the diagnosis and treatment of cancer. The unique properties of gold nanoparticles, known as localized surface plasmon resonance, make it possible to create theranostic agents based on these nanoparticles, combining the capabilities of both in vitro diagnostics and targeted drug delivery. The high surface-area-to-volume ratio of gold nanoparticles significantly facilitates the creation of complex nanoplatforms, which can be used in several therapeutic and diagnostic areas at once.
