Nanoglue Could Be Used To Make Spiderman Web-Shooters

Stony Stevenson writes "A team of US researchers is using the super-adhesive properties of nanoglue to create a super-sticky web-shooting device much like the comic-book hero Spiderman's. The nanoglue is also being trialed in the production of computer chip circuitry and is expected to miniaturize the process, meaning faster and more powerful chips. From the article: '"If we can find a way to create threads and/or intertwined bundles using the molecules in a scalable fashion, while retaining the adhesive properties, then creating web-shooters similar to Spiderman's is a real possibility," Ramanath said. "There are ways in which molecular threads/bundles can be created in large quantities. The challenge will be, however, to simultaneously engineer adhesion on certain surfaces (and not others, since we want the suit only to form on the desired surface) and also with each other during the thread formation."'"

Well, glad *that's* finally solved. Now, on to cancer...

Would you people please grow up. For one thing, the "Cure Cancer" meme needs to die. There is never going to be a magic bullet solution to cancer, because cancer refers to large and diverse class of diseases that really only share one trait in common. That being the anomalous and detrimental growth of new tissue. Some cancers are causes by Viruses, some by other diseases, some by exposure to radiation, some are caused by genetic predisposition. Work on the treatment of any of these diseases requires an exceptional command of highly diverse and complex fields of knowledge. By and large, the people can contribute generally are, and the ones who aren't directly are usually working in related fields that may serendipitously lead to major breakthroughs. Get over it.

And secondly, are you seriously suggesting that humanity should give up all other pursuits in order to work on this problem? There are other diseases you know. And other problems that face humanity. Besides that, how do you know that this project, as frivolous as it may sound, may not produce some knowledge that will contribute to the treatment of disease?

Original Journal Article

Actually, this article seems to miss the point. Ramanath's research on this was just published in Nature (abstract) and actually has far more application to bonding chip microstructures than to web-slinging!

Here we harness MNLs (molecular nanolayers) at thin-film interfaces at temperatures higher than the MNL desorption temperature to fortify copper-dielectric interfaces relevant to wiring in micro- and nano-electronic devices. Annealing Cu/MNL/SiO2 structures at 400-700 C results in interfaces that are five times tougher than pristine Cu/SiO2 structures, yielding values exceeding approx20 J m-2

While I do somewhat agree with the sentiment of the above poster that 'there are more important things that we could be working on', I think that it would be fair to remember that not ever scientist is suited to work on every project - to work on "cancer" (as it is so broadly put) you need certain kinds of scientists - i.e. biochemists, molecular & cellular biologists, organic & medicinal chemists, and pharmacists in order to do direct research on cancer. This fellow (G. Ramanath) is a materials engineer, and thus would be ill equipped to doing cancer-curing research.
However, it should be noted that the ability to DO cancer research is only made possible by discoveries in other areas of science - physics (radiation therapy, imaging methods), engineering (devising machines to test for and to visualize cancerous growths), chemistry (new ways to make and deliver drugs), materials science (better materials to do all of the above!) , computing science (imaging, modelling), and biochemistry & biology (understanding cellular processes) by those who are not aiming to cure diseases, but whom seek to advance the limits of human knowledge and understanding. Creating a better glue just happens to be one such advance that may help indirectly.

The REAL application is high-density memory.

Check out this part of the article:


This is where the Ramathan's nanolayer bonding comes into play. Because the nanoglue forms such a strong bond and also prevents the copper and silica from mixing, the use of tantalum can be eliminated from the equation, effectively shrinking the space between the two materials from about 15 nanometres to one nanometre.


One nanometer. Current Flash memory can't go below 40 nm right now. If/when Ramathan's discovery gets applied to the industry, it'll be quite a boost for reaching smaller and more energy-efficient computers.
