In the past, people learned dragonflies to build airplanes. This animal’s eye structure is also studied to apply to the camera or artificial eye for the blind.

Now, the dragonflies continue to prove they must be a master of creation. Scientists this time observed the natural ability to kill bacteria on dragonfly wings, and once again wanted to learn them.

Not a simple flat surface as we see it, dragonfly wings are rough because they contain microbial traps. On a microscope, you can see that they look like a nail table, mixed with sharp bottle fragments.So, don’t ask why once bacteria have fallen on dragonfly wings, they cannot survive.

In many attempts to create bactericidal surfaces, scientists have coated it with chemicals. But then we know, chemicals as well as antibiotics will gradually lose their effects over time, as bacteria begin to learn to resist them.

So today, a promising research direction for creating a bactericidal surface is to set up traps. They are like a tiny table, made of black silicon nanorods pointing up into the sky. And because traps kill bacteria on a physical basis, they are not as resistant as antibiotics.

Bacteria tearing tables lie in a broad field of study, called nano textured surfaces (NTS). This field receives great attention from many scientists. Because nanostructures exist in nature and they are worth learning from.

For example, a nano surface covers clothing, shoes, and makes items waterproof, which is what is modeled on the surface of lotus leaves. In the case of the silicon nanotube ripping off bacteria, it was something similar to the wing surfaces of dragonflies.Scientists previously knew that a nail on a dragonfly can kill bacteria, by puncturing their cell walls. But they want to see this first-hand in new research.

Using super powerful electron microscopes, scientists in Australia and Nigeria have finally managed to achieve this. Moreover, they also discovered many things that we still mistakenly believe.It turns out that the spikes that nature creates are not what we see in the circus. But that would be the case for them to kill the bacteria.

First, a nail table on the dragonfly wing does not come up from identical nails. As a principle scientists in the field of nanotechnology “memorize”, everything must be made as homogeneous as possible.

For example, for a surface to be water resistant, it must be made up of identical nano “umbrellas” and leveled together. But in the case of a nail, it is not. You will never see a circus performer pierced by nails on the table, because they are so close and identical.

The question is that how a nailing table will be more dangerous? It turns out, it must be jagged and jagged, containing sharp nails, the one being high and low and mixed with broken bottle fragments.That’s exactly what you see on a dragonfly
