Nanotechnology or the technology of infinitesimal particles, is that science that is concerned with the study of the treatment of matter on the atomic and molecular scale. Since the origin of the earth, nature has not stopped developing, and living organisms have had to adapt to changing conditions, in order to ensure continuity.
This amazing development at the nano level is not realized by the naked eye, and it is an important source of knowledge surrounding us from changes such as global warming and lack of resources and others, and this makes us resort to nature and study living organisms, nature has advanced nano structures that we may take inspiration from to build a creative future, or we know why you prefer Nature has some solutions.
Evolution of living organisms to adapt.. Nature’s solutions
Physicist Serge Bertier says: The nanoworld cannot be imagined. A nano is a billionth of a meter.
Life begins at the nano level, where the size of one part is a nanometer, and on this basis the molecules acquire their properties, and biological nanostructures provide the organic molecules of living organisms with many of the characteristics necessary for survival, giving them their colors and the ability to smell and crawl on the ground, as is the case of snakes.
Chemist Bernd Cholhun says: We have realized that everything that appears to us is clear in fish, birds, plants, butterflies, and others; It exists because nature is built on this scale in an efficient and economical way. Two centuries ago we discovered entire animals and today we discover nature, in short because we changed the scale. We have the technological means to re-evaluate the world at the nanoscale.
This advanced science reveals a nanoworld hidden from the naked eye and organized differently from our technical world. Nature has developed effective, multifunctional and complex solutions that allow living organisms to continuously adapt to their environment and naturally adapt to the four elements: earth, water, fire and air.
Snakes have the ability to move while crawling, leaning on the tips of their tails, they can release their bodies in fractions of a second.
The movement of reptiles… the struggle of bodies against the roughness of the earth
On land, the friction with the ground is harsh. Some lands are smooth, while others are steep and rugged or submerged when walking. How did reptiles adapt to these various situations?
Snakes have the ability to move while they crawl, leaning on the tips of their tails, they can release their bodies in fractions of a second, but how can they crawl on rough soil that can scrape their scales.
When you touch the green whip snake, it feels very soft, although it is covered with a tissue of thorns, but it is nano-thorns, and when it is the right size, a slight change in color appears due to the nanostructures, which is the iris color.
Bertier says: All the thorns are intact, because they are made of a soft substance called chitin, and this is a genius feature. This means that it almost floats to the surface, as it barely touches the sand.
The snail has a shock-resistant feature. This small mollusk has a shell that is considered a masterpiece of technology, which is a ceramic composed of the mineral argonite, and it can build its shell at room temperature, while humans need a very high temperature to make the same thing.
Orognite is stacked in small adjacent tiles and in multiple layers, and when the shell is subjected to a shock, the tiles remain attached to each other, by means of proteins that weld them together in an elastic way, and thus the tiles slide over each other sideways and absorb energy, preventing the collision wave from penetrating deep inside the shell, thus creating a protection for the body of the snail.
The bee’s eye consists of a thousand individual units, each of which has a specific photo receptor, each of which sees certain colors of the spectrum.
Newton’s colors…the balance of sight for living creatures
There are nano structures that are not visible to the naked eye, but on the other hand, there are others that are colorfully exposed thanks to sunlight and light reflection, but do different living things see colors in the same way?
Bertier says: We can analyze the sun’s rays. If we take an object that scatters the sun’s rays, what we see is the visible part of the solar spectrum, but the solar spectrum is wider than this, there are red rays and ultraviolet rays, and here Newton’s colors can be seen; Violet, blue, indigo, green, yellow, orange and red, these are the colors we humans can see.
As for other organisms, they have different eyes and visual devices, and thus their vision is different. Snakes see much more in the infrared spectrum, and some organisms have very poor eyesight, and birds and insects see little red waves, while they see better blue, violet and ultraviolet waves.

The production of iridescence.. the trick of flowers to attract pollinators
Cambridge University Garden Director Professor Beverly Glooms studies strategies developed by flowers to exploit the help of bees and insects. Beverly says: My research is based on how flowers attract pollinating animal species, and how they transform a primary flower into four hundred thousand different species, and each type attracts different insects from bedding, bees, flies and birds, depending on the diversity of its colors, shapes and patterns.
Plants use two nanostructures to produce iridescence, called.
The first is called a diffraction grating, which is a set of regularly spaced edges that interfere with light and produce iridescence, which is found in flower petals.
The second type is multi-layered, and consists of cell walls separated by air gaps, and is found in fruits and leaves, and iridescence is caused by folds and wrinkling of the skin, and iridescence is visible to the bee because of its special optical spectrum based on a complex natural geometry that enables it to find flowers more quickly .
Glomes says: Bees see through photoreceptors in their eyes. The eye of a bee is made up of a thousand individual units, each of which has a specific photoreceptor, some see blue, and some see ultraviolet rays, and thus its brain receives signals to see a complete picture.
