Small is usually being used to describe a thing that have the petite size. However, when someone said, “The smallest”, it could be something that very small, or might be we cannot detect it with our bare eyes!
Although it’s a little bit hard to believe, but according to Peer Fischer, a experienced technology researchers from The Rowland Institute at Harvard University, had invented a very spectacular technology: A remote-controlled nanopropeller, which is have the look like sperm but mimic the corkscrew motion of flagella.
According Fischer explanation, Flagella are the structure some bacteria use to swim through water. Instead of swimming through it, the Flagella mostly use a corkscrew motion to drive bacteria through the water. By this way, it can save up more energy!
Fischer clarified that the motion of flagella is inspired him and his colleagues, Ambarish Ghosh to build this incredibly and powerful nanopropellers. Actually, they’re made of glass, and each of them has a spherical head about 200 to 300 nanometers across. A corkscrew-shaped tail is attached on the nanopropeller, which is measured up to 2 micrometer long. To be honest, it’s even smaller than human sperm, as it sized about one-tenth the length of a human sperm!
Pretty impressive, isn’t it? Fischer and his teammate suggested that in one day, these nanopropellers would be used for deliver drugs or antidote to any of the human body parts without hassle!
