Document Summary
Nature: metal nps that are naturally found in the environment (i. e silver and gold) Applications of nanoparticles engineering, electronics, optics, consumer products, alternative energy, soil and water remediation. Quantum dot: semiconductor nanocrystals that identify the location of cancer cells in the body. Nanoparticles: that deliver chemotherapy drugs directly to cancer cells to minimize damage to healthy cells. Nanoshells: that concentrate the heat from infrared light to destroy cancer cells with minimal damage to surrounding healthy cells (ie, nano shells as cancer. Therapy: injected into cancer area and they recognize biomarkers on the surface of cancer cells, shine near-infrared (nir) light, the heat generated by the light-absorbing nano-shells can successfully kill tumor cells while leaving neighboring cells intact. Nanotubes: used in broken bones to provide a structure for new bone material to grow. New field (a couple decades old: the first nanotoxicology paper were published in 1990s, the first paper of nanoecotoxicology didn"t come out until 2006.
