Nanothreads to "spin" new tissues?

October 30th 2007 13:58
Cell sized nano threads can be used to spin living cells as published in Scientific American journal News on 2nd October.

Recent research at the University College, London has lead to the discovery of a method of using just pressure to spin nano threads on living heart tissues. This can help in the regeneration of the heart and can also be used to "create" fresh skin. This is an extension of the application of nanotechnology in the field of heath sciences in a novel area where its need is great. Such research will lead to potential techniques to heal irreversible damages to the skin such as with burns or for heart cell damage as seen in associated with heart attacks.

This research has been successful with rabbit aortas till date and is in the process of further clinical trials. The team from this University is also testing gene production of the resultant cellular nano threads to determine their safety. Research is also underway to obtain nano threads from stem cells. Stem cells, as we all know have the ability to differentiate into almost any cell type so that these nano threads can be used for the regeneration and repair of any tissue/cell in the body.

Nanotechnology in Medicine

September 1st 2007 04:08
Small is beautiful but with nanotechnology small can become powerful. Disease and ill health are largely caused by damages at the molecular and cellular level. Today's surgical tools are, at this scale, large and crude and from the viewpoint of a cell, even a fine scalpel is a blunt instrument more suited to tear and injure than heal and cure. Modern surgery works only because cells have a remarkable ability to regroup, bury their dead and heal over the injury.

Nanotechnology, "the manufacturing technology of the 21st century," will help build a broad range of complex molecular machines (including, molecular computers). It will let us build fleets of computer controlled molecular tools much smaller than a human cell and built with the accuracy and precision of drug molecules. Such tools will let medicine, for the first time; intervene in a sophisticated and controlled way at the cellular and molecular level. They could remove obstructions in the circulatory system, kill cancer cells, or take over the function of sub cellular organelles. Just as today we have the artificial heart, so in the future we could have the artificial mitochondrion.

Equally dramatic, nanotechnology will give us new instruments to examine tissue in unprecedented detail. Sensors smaller than a cell, could give us an inside and exquisitely precise look at ongoing metabolic functions at a molecular level. Tissue either chemically fixed or flash frozen could be analyzed literally down to the molecular level, giving a completely detailed "snapshot" of cellular, sub cellular and molecular activities. Nano-pharmacology, a field currently being developed can use nano-engineered delivery mechanisms to release pharmaceuticals (or other bio-reactive substances like oxygen) into the body.

Nanotechnology is expected to touch almost every aspect of our lives, right down to the water we drink and the air we breathe. Nanotechnology will improve our lives in any area that would benefit from the development of better, faster, stronger, smaller, and cheaper systems. The medical area of nanotechnology application is one of the most potentially valuable, with many projected benefits to humanity.

Nanotechnology: Aid for the new era Spiderman?

August 31st 2007 08:07
I recently read an article published in Technology review and found the topic very interesting. A carbon nanotube based adhesive tape has been developed after extensive research to aid climbing walls!

The study of this theory of developing adhesions based on the wall climbing skills of Spiders and Geckos has been going on for some time as an article was published in the Journal of Physics on August 2002 regarding this. Though climbing walls has been envisioned and portrayed for a long time, there have been no real developments to make this a reality

Well who knows it may become popular and replace elevators!!!! (after another 10 - 15 years, hmmm maybe)
