The impact of size on tissue distribution and elimination by single intravenous injection of silica nanoparticles.

Many approaches for the application of nano-sized particles to the human body as nanotechnology have been recently developed. The size of nanoparticles is related to their useful character and also plays a key role in toxicity. Since this surface area can interact with biological components of cells, nanoparticles can be more reactive in than larger particles.
