Question

What are three ways in which scientists think the nanoparticles might cause inflammation that leads to nerve damage once they reach the brain?

Answer 1

Exposure through ingestion, Exposure through inhalation, Exposure through skin contact are some ways scientists think the nanoparticles might cause inflammation when they reach the brain.

After ingestion, nanoparticles encounter a series of barriers and tight junctions. If the size is reduced, nanoparticles can cross the blood-brain barrier and accumulate in the brain.

In terms of accidental inhalation, the nanoparticles that pose a high risk have dimensions < 0.5 µm, can cross the thin epithelium and reach the blood capillaries. Furthermore they can be absorbed through the olfactory epithelium and reach the brain.
