Are Emerging Applications of Carbon Nanotubes Safe?

Carbon nanotubes are tiny cage like structures with great potentials in biomedical engineering and sciences. However, their great emergence in bioscience applications is not risk free. In present report several known or possible risks and limitations of carbon nanotube material in biosciences and bioengineering are documented. Major breakthroughs of carbon nanotubes such as MRI buckyballs, computing elctronics, tiny diagnostic chips, solar tubes, plasma displays, neural sensors, healing drops, drug nanospheres, nanocircuits, nanobullets, nanomonitors, nanomedicine, chemodots are exciting. Other hand, it also poses serious question on unsafe use of carbon nanotubes such as tiny toxins, nano-explosives, smart intruder targeting nanomolecules. A critical view of limited outcome from each application is presented with possiblility of limited use of bio-applicable carbon nanotubes to get maximum outcome in future.
