Robotic Nano-Spiders Made of DNA Molecules

[Deadstring67]

---

A group of scientists from Columbia University managed to invent extremely small spider robots measuring about 4nm across. If you wish to compare, these nano robots are about 100,000 times smaller than the diameter of a human hair.

It would be interesting to note that the spider robots are made of DNA molecules. They can walk, turn right and left and create their own products. Developed at the molecular level, the robots represent DNA walkers, featuring legs to walk autonomously, though very slow - about 100nm in 30 meters - 1 hour.

In order to observe the spider robots scientists used atomic force microscopy. The molecular robots managed to attract a lot of attention due to the fact that they can be programmed to sense the environment and react accordingly. For example, they can detect disease markers on a cell surface, identify whether it is a cancerous one and then bring a compound to kill it, if necessary.

Researchers consider that their latest invention is an important step in molecular robotics. Although today this field cannot boast many great inventions, scientists and engineers believe that in the near future it could become one of the most important industries that could create devices for various medical applications.

nice.......

Soon, kini pud gamiton as weapons.. whew.

[dicklesshorseman]

aahh pareho jud ni sa G.I. Joe na movies. endless ang possibilities pwede himoon sa mga nanobots.

nice...pero ang blema ani kung gam8on ni in bad way...

[istoryamember]

ngilngiga ani da. kuyaw jud magamit ni sa binuang kay dili baya ni makit-an

This is nice! First step towards real nanotech. But don't get too overexcited. Despite the greatness of the achievement, it is far from the reality of what you might expect from sci-fi movies. If you're interested of the source publication, I downloaded and uploaded it here. nature09012.pdf The spider-like robot is really built from DNA but it is still from from real robots that you can really control or like the artist's impression posted by the TS.

dili ni makita sa naked eye...

pero cool cya to thnk about
