Laser material processing lead to nanotoxicity

Laser ablation is frequently used in the industry in cutting and drilling processes of materials. During these processes, nanoparticles are produced in the air as byproducts [1]. Since these nanoparticles will accumulate in the environment, the workers in that place are exposed to those nanoparticles. It was shown that when animals are exposed to nanoparticles via inhalation, nanoparticles enter systemic circulation via alveolar epithelium. Nanoparticles travel through the systemic circulation to reach vital organs like heart, brain and liver [2]. Those nanoparticles lead to disruption of a number of cellular signaling pathways and consequently result in cellular toxicity [3].
