They give animals a particular evolution like X-men, which is nanotechnology …
The animal kingdom has a variety of shapes ranging from long-necked giraffes, spoon-shaped bird beaks to the sharp claws of predators.
But evolution also worked on a much smaller scale. It’s about creating nanostructures – parts less than 1/20 the width of human hair – to help animals climb, camouflage themselves, flirt … with supernatural abilities like characters in the movie X -men.
Let’s explore some animals that applied nanotechnology below.
1. Beautiful wings
Many of the butterfly’s shimmering colors are not made of cellular pigments but of nanostructures. The top of the wing is interspersed with grooves and pits made of a protein called chitin.
The scattering of light gives the butterfly an iridescent color – meaning its color changes with every angle.
When affected by heat in the form of invisible infrared radiation, chitin nanostructures expand, change shape, and thereby change color.
3. Flashy feathers
Butterflies aren’t the only species to use nanostructures in beauty care. In Australia and New Zealand, Eudyptula minor pigeons are found with dark blue feathers instead of the traditional black.
The 180 nm wide strands are made of beta-keratin, a protein also found in human hair. Similar fibers have been found in a number of other blue-skinned birds, but have never been found in feathers.
3. The pigment produces electricity
Most wasps are most active in the morning and disappear by noon. However, this is not true for oriental wasps – the most productive workers in the sun.
According to the study, the nanostructures of this bee’s exoskeleton form a type of solar cell that collects light and energizes the bee.
The brown tissue in the belly of the oriental wasp contains melanin – a pigment that protects the skin by absorbing ultraviolet rays and turning it into heat.
In addition, the structure of these colorful fabrics also includes many grooves that “trap” the light and cut it into many smaller rays. Meanwhile, the yellow tissue of bees containing xanthopterin can convert light into electricity.
This is why this bee is the most productive at midday. It also explains an earlier study where anesthetized oriental wasps woke up earlier if exposed to UV light.
4. Slippery leather set
Snakes seem to crawl very easily with their catfish, but their movements are actually a complex interplay of muscle movements and small-scale physique.
It protrudes about 200nm above the skin, allowing the snake to glide forward smoothly while preventing any backward movement.
The friction pointing in one direction also prevents the snake from sliding out of its way even when it is on an inclined surface.
5. Nano toes
Tokay’s geckos use nanotechnology to hang themselves from trees, walls, windows, and even ceilings. The gecko’s feet are covered with microscopic hairs called bristles.
The synergy was so strong that the gecko could give its whole body with just one toe, even on a piece of glass. Engineers mimicked the gecko’s structure to create super-sticky tape, glue, and even a climbing robot.
6. Super durable silk yarns
Spider silk is one of the strongest materials known to humans. It is stronger than steel, they can withstand the force of the wind and catch flying insects without breaking it
