Nanotechnology What is Nano material and Nanotechnology

Nanotechnology - What is Nanotechnology?


Nanotechnology refers to the study and development of tiny materials. These materials consist of microscopic particles which can be used to produce various items and designs. They can be utilized in consumer products. The use of nanometer-sized materials can be traced back to hundreds of years. The 4th century was when Roman artists realized that gold and silver particles can be used to make glass. In this experiment, the metallic particles were suspended in a glass solution. The result was a glass cup that is now referred to as the Lycurgus Cup.


Structures


Nanostructures are a great choice for a variety of applications due to their unique properties. They're small, with less than one meter and are created through various methods. Certain techniques are easy, such as solution processing while others require advanced technology, such as lithography. There are numerous industrial applications that utilize nanostructured materials. Nanostructured materials can also be useful in a variety of other areas, including biomedical, textiles and sensors.


Dispersions made of nanoparticles make up the majority of nanomaterials. However there are other materials which employ nanostructures. Metal organic frameworks (MOFs) are an example of this, because they contain nano-voids within their crystal structure. The voids permit the MOFs to serve as carriers for molecules and active pharmaceutical ingredients. They can be released directly into tissues, which makes them useful to deliver drugs.


Properties


Nanomaterials are tiny, tiny particles that have distinct physical and chemical properties. Nanoparticles have a major influence on their toxicity as well as biological activity. Other characteristics of nanomaterials are surface area and surface chemistry. Nanomaterials are also able to aggregate. Understanding these properties is critical in developing safe applications of nanomaterials.


Nanoparticles are smaller in atoms than bulk materials, so they can react with chemicals. For example, gold is inert on large scales but at nanoscale, it is catalyst, which can be used to oxidize carbon monoxide along with other chemicals. Another material that is unique in its characteristics is glass. It is fragile and may be damaged or even have microcracks that may cause rapid fractures.


Applications


Nano-materials have a high strength and light weight and can be utilized for many different uses. As an example, these substances can reduce the weight of commercial jet aircraft which can help save fuel by up to 15 percent. These materials also can reduce the weight by as much as 33% for launch vehicles. These materials can be used across many areas of our lives from transport to medical.


Nanomaterials are also used for biomedical purposes for coating vaccines, filters, and medications. In addition, nanomaterials can aid in fighting various viruses and diseases.


Health affects


While scientists are moving forward in understanding the toxicity of engineered nanomaterials However, it's still far from understanding the full impact on the human body. There are, for instance, still gaps in our knowledge regarding how nanomaterials are absorbed into the body and the way they travel. Further research is required to fill these gaps.


Nanoparticles could pass through cell membranes and into the bloodstream and other organs. Nanoparticles also possess a greater surface area to volume ratio than larger particles. This means they can hold larger molecules. Consequently, their toxicity depends on the chemical composition and surface characteristics. Fortunately, it is possible to alter the surfaces of nanoparticles in order to make them less harmful.tongruncms
