Carbon nanotubes risks and limits

carbon nanotubes risks and limits

 

TIGER Killian's insight:

We saw carbon nanotubes have lots of applications, but not just in the biological domain.

 

However, there is a risk in the use of these carbon nanotubes.

There're no  short-term issues, but, in the long term,there could be some problems.

Scientists found that carbon nanotubes using antibodies can influence the immune system, because the use of a lot of antibodies in the nanotube has been associated with a significant decrease in the immunoreactivity of the patient.

In the long-term, there could be some pulmonary issues.

Scientists observed complication when they tested nanotubes on rodents.

 

To conclude this article we can say that there are some issues discovered but a lot of research has to be done to rationalise them

Carbon nanotubes uses

TIGER Killian's insight:

Single and multi-walled carbon nanotubes (CNTs) have remarkable thermal, biologic and electromagnetic properties that suggest a wide range of application.

 

Several highly promising examples have been highlighted in the literature, ranging from their use as growth substrates or tissue scaffolds to acting as intracellular transporters for various therapeutic and diagnostic agents

 

The nanotubes are used against cancers. Because they can deliver innovative drugs, and this technic targets more efficiently than other technologies like radiotherapy. These results suggest that CNTs may be useful vehicles for transporting radionuclides.

Moreover, cargoes can be attached to the surface of the nanotube, inside or outside the nanotube wall. Thanks to this technic, the nanotube can go through the cell membrane, and thus it can deliver the drug into the cell or in many cases in the nucleus.

To improve this, you can add to the nanotube, antibodies and the nanotube would be even more efficient.

They also have a strong optical absorption in the near-infrared region, and thus they can help to the ablation of tumors because thanks to the nanotube we can clearly see the tumor with a biological imaging.

 

So Carbon Nanotubes have a lot of applications in the biological domain, but more specificly in the oncology domain. They can also be used like a protein delivery system, they also can kill a cell when it blows up with radio waves, they can also repair nervous connection ...

carbon nanotube

TIGER Killian's insight:

Nanotubes were discovered randomly, in fact, their exeptional structures, caught the scientist attention and their potential of exploitation is promising

But, what's a carbon nanotube ?

The nanotubes were discovered by Jumio Lijima in 1991, and since this time, researchers have worked on their propreties, and their uses.

"Nanotubes are hollow, closed strands with a diameter of the order of a nanometre. These synthetic filaments, which display remarkable electrical, mechanical, chemical and thermal properties, are the subject of intense interest in the domain of nanotechnologies. They have many potential applications, especially in the fields of microelectronics and materials."

"Nanotubes are made up of sheets of atomes rolled up on themselves, in which the atoms are organised in a honeycomb-type structure. Today, these nanostructures (6 times lighter than steel and more than two hundred times as strong) are raising tremendous hopes."

This is acording to the universcience dictionnary.
