Chronic inhalation of crystalline silica is an occupational hazard that results in silicosis due to the toxicity of silica particles to lung cells.
It is thus surprising to read that silica nanoparticles are extensively applied for drug delivery Silica particles are used as conveyors of drugs with low bioavailability. Even for artemether.
