Nanotechnology What exactly is Nanotechnology?
Nanotechnology, is the study of tiny materials. They are composed of tiny particles that can be transformed into a variety of products and structures. These substances can be used in consumer products. There have been hundreds of years of usage of nanometer-sized materials. Roman artists realized that silver and gold particles could be used to create glass in the fourth century. The metals were suspended in a solution made of glass. The result was the Lycurgus Cup.
Nanostructures are characterized by properties that make them suitable for many applications. Nanostructures are less than 1 millimeter in size. They can be constructed using different methods. Although some methods are simple such as solution processing, others require advanced techniques like lithography. Nanostructured materials are a great choice for industrial uses. Nanostructured materials also have value in many different fields, like sensors, biomedical and textiles.
Most nanomaterials consist of dispersions of nanoparticles however, some other materials make use of nanostructures. One example is metal organic frameworks (MOFs) which include nano-voids inside their crystal structures. These voids enable the MOFs serve as hosts for pharmaceutical active ingredients as well as molecules. They are able to be released directly into tissues and are therefore useful in drug delivery.
Nanomaterials are small particles that have unique chemical and physical characteristics. Nanoparticles can have an enormous influence on their toxicity as well as biological activity. Other important properties of nanomaterials are surface area and surface chemistry. Nanomaterials also have the ability to form agglomerates. These properties are vital for an effective use of nanomaterials.
Since nanoparticles are much smaller than bulk substances, they are able to react with chemicals. For example, gold is inert at larger scales but at nanoscale, it acts as catalyst, as it oxidizes carbon monoxide and other chemicals. Another material with unique property is glass. Glass is very fragile and it can be damaged or have microcracks that may cause rapid fracture.
Nano-materials possess high strength and light weight and can be utilized for many different applications. For example, these materials can help reduce the weight of commercial jets, which can save fuel by up to 15 percent. They also help to reduce the weight of launch vehicles by 64 percent. These materials can be utilized across many areas of our lives including transportation, medicine and even transportation.
Nanomaterials also have biomedical applications that include coating vaccines filters, as well as drugs. Additionally, nanomaterials could aid in fighting various viruses and illnesses.
The scientific community is moving forward in understanding the toxicity of engineered nanomaterials yet it is still far from knowing the full range of effects on the human body. There are gaps in knowledge on, for instance, the ways of exposure as well as how nanomaterials are taken up in and distributed throughout the body. These gaps have to be filled through additional research.
Nanoparticles can be able to cross cell membranes and get into blood and other organs. They also have greater surface area ratios than bigger particles, this means they can hold larger molecules. In turn, their toxicity varies on their chemical composition and physical characteristics. It is, however, possible to alter the surfaces of nanoparticles to make them less damaging.tongruncms
