Manipulating matter at an atomic and sub-molecular level has paved unconventional drawing technique with children 4 years way for major breakthroughs in chemistry, biology, and medicine.

Yet, the unfolding applications of nanotechnology are far broader and more diverse than what we’ve imagined. 1980s, the field of nanotechnology might have remained science fiction. With its atomic precision the STM has enabled physicists to study the structure of matter in a way that was impossible with conventional microscopes. The astonishing potential of STM was demonstrated by researchers at IBM when they created A Boy and His Atom, which was the world’s smallest animated film. It was produced by moving individual atoms on a copper surface.

The 90-second movie depicts a boy made of carbon monoxide molecules playing with a ball, dancing, and bouncing on a trampoline. 1000 the size of a single human hair. The global expenditure for oil exploration has risen exponentially during the past decade. However, efficiency in oil recovery has remained a major issue. When petroleum companies shut down an oil well, less than half of the oil in the reservoir is extracted. The solution is enhancing an existing drilling technique. The original technique involves injecting water into the rock pores where oil is located.

This displaces the oil and forces it out. However, this method reveals its limitation as soon as the oil in the easily reached pores has been extracted. By then, water begins emerging from the well instead of oil. To prevent this, Chinese researchers Peng and Ming Yuan Li have come up with the idea of infusing the water with nanoparticles that can plug the passages between the rock pores.

This method is intended to make the water take narrower paths into the pores that contain oil and force the oil out. With successful field studies conducted in China, this method has proven highly efficient in recovering the 50 percent of the black gold that otherwise remains out of reach. The images on computer screens are presented via tiny dots called pixels. Regardless of their sizes and shapes, the number of pixels on a screen has remained a determining factor of image quality. With traditional displays, however, more pixels meant larger and bulkier screens—an obvious limitation. While companies were busy selling their colossal screens to consumers, scientists from Oxford University have discovered a way to create pixels that are just a few hundred nanometers across. The nano-pixels will serve a variety of purposes where the conventional pixels have become impractical.
