Nano science is the science of structures and materials at the scale of nanometers. A nanometer is one billion t of a meter, which is 1 0 times the power of - 9. When matter is divided into these small objects, the mechanical, electrical, optical, magnetic and other properties are altered. Nano Technology is the technology involved in the design, production, characterization and application of nano-structured materials. Solids are composed of particles, each of which has a specific number of atoms, which may vary from material to material. If a solid particle is smaller than 100 nm, it is called a nano solid. If the particle size is greater than 100 nm, then it is called a bulk solid. It is important to note that nano and bulk solid may be the same chemical.
Nano-scale structures have existed in nature for thousands of years before they were studied in labs. A few examples A single molecule of DNA, the building block of all living organisms, is about three nanometres in width. The wings of the morph o butterfly contain nano-scale structures that alter the manner in which light waves interact, giving them metallic-blue and green colors. Color manipulation by changing the size of the nano particles that are used to create the materials.
Peacock feather get their luminous hue from light collaborating with 2 layered photograph precious stones structures only many nano meters thick. Comparative nano structures are made in lab to gleam in various varieties. parrot fish crunches up coral all day.The wellsprings of the parrot fish's strong chomp is both entomb woven fiber called nano structures. precious stones of a mineral assembled influenza or apatite are woven in a junk mail like arrangement.this structures gives parrot fish teeth is extraordinary in strength. The regular designs gives a plan to making ultra sturdy engineered materials that could be helpful for mechanical parts in hardware, and in different gadgets that under g o redundant movement,abrasion and contact pressure And so on.
Nanoparticles, can have similar aspects as natural particles like proteins. Some of the large molecules that enter the body's tissues and fluids may immediately adsorb onto the surface of living systems. This capacity of nanoparticles to have atoms "staying" to their surface relies upon the surface qualities of the particles and can be significant for drug conveyance utilizes. Indeed, nanoparticles can be designed to adsorb specifically onto the surface of the target cell in order to deliver a drug directly to that cell in the body. However, the dimensions of the nanoparticles also have an impact on how they interact with living systems. For example, nanoparticles no greater than a couple of nanometres might arrive at well inside biomolecules, which isn't feasible for bigger nanoparticles. Nanoparticles might cross cell films. It has been accounted for that breathed in nanoparticles can arrive at the blood and may arrive at other objective destinations like the liver, heart or platelets. Key variables in the cooperation with living designs incorporate nanoparticle portion, the capacity of nanoparticles to spread inside the body, as well as their dissolvability. Some nanoparticles break up effectively and their impacts on living life forms are equivalent with the impacts of the substance they are made of. In any case, other nanoparticles don't corrupt or break up promptly. All things being equal, they might gather in natural frameworks and endure for quite a while, which makes such nanoparticles of specific concern. There stay numerous obscure insights regarding the association of nanoparticles and natural frameworks and more data on the reaction of living life forms to the presence of nanoparticles of differing size, shape, substance organization and surface attributes is expected to comprehend and sort the harmfulness of nanoparticles.
