The Pros And Cons Of Green Nanotechnology

Working with nanoparticles is critical due to its nanoscale; they should be handled carefully considering safety

Nanoparticles are being used in a diverse range of products for multiple applications which increases the chances to contaminate the environment. Nanomaterial can be released accidentally or intentionally. Being released to air, soil and water NPs pose threat as they are very small particles and can float into air or get transported to another place through water. Soil contamination leads to accumulation for long time and further pollutes ground water (Tripathi et al. 2012). Among the applications coatings, paints, and pigments are quite important and have the highest possibility of being released into soil and water. Electronics and optics signify a major application, and NPs used are more likely to be disposed in landfills. Nanoparticles

Nanotechnology is a novel technology what generally deals with structures and systems with a size less than 100nm. [1] Due to its unique tiny size, the properties are quite different from bulk properties include physical properties, chemistry properties, biological properties. For example, gold in bulk form is inert, but in nano scale, it tends to be very active. Moreover, different sizes, structures, and surface areas of gold nanoparticles make it exhibit different colors.

The idea of nanotechnology was first discovered by nobel prize winner physicist Richard Feynman in 1959. In the 1980 the first SPM was developed by IBM scientist in zurich. In 1991 a new form of carbon was discovered, the nanotube which was soon later on used for one of the building block for nanomaterial and nanomachines. In 1986 a book written by Eric Drexler spared the public interest in nanotechnology since the the NNI started by president Bill Clinton invested millions which in 2020 would turn into one trillion dollars. Nanotechnology is used in many things today like sunscreen, cars, in computers, medicine and in many other things to come in the future and in today's day and

This book by Hornyak and partners brings into perspective an integrated introduction to the nanoscience and its applications. The book further presents illustrations in full color regarding nanotechnology. From these illustrations, I will be developing a detailed understanding of the fundamentals of nanotechnology. I will also be acquiring knowledge on the different aspects of nanotechnology including chemistry, physics, and biology. The authors also discuss the impacts of nanotechnology on the society, which is also an important part of my paper. I will be gathering information on industrial concerns associated with nanotechnology in manufacturing and safety. This will broaden my discussion to a better-informed approach in explaining implications of nanotechnology in the modern

Nanoparticles are materials with overall dimensions less then one hundred nanometers, they are also known as zero-dimensional materials. These particles differ from other nanomaterials because all their dimensions are in nanoscale, apposed to one dimensional or two-dimensional nanomaterials which have one or two dimensions greater then a nanoscale. Nanoparticles have amazing applications in medicine pushing the boundaries of what we can accomplish in areas like medical imaging and drug and gene delivery. Nanoparticles are replacing conventional organic dyes used to dye tissue and cells for imagining with quantum dots. In drug delivery, they are using natural nano-polymers delivery methods to increase the solubility of drugs and prolong the

Abstract: “Nanoparticle vaccines”, an article written by Liang Zhao et al. condenses a large amount of information on the topic of nanovaccinology and presents that information in an organized and straightforward manner, however, it only scratches of the field and the lack of clarity relating to its audience can lead to it being confusing. The article could prove useful to a scientist possibly interested in doing research in nanovaccinology, however it would likely not be any new information for experts in the field.

Nanotechnology involves the handling of functional systems at a very small scale (Bamrungsap, Zhao, Chen, Wang, Fu, Tan & Li, 2012). When talking about nanotechnology in relation to health, it can commonly be referred to as nanomedicine. Nanotechnology, specifically nanoparticles, have had a recent uprising in research studies. Fortunately new studies are proving to show how nanoparticles can aid in the diagnosis and treatment of lung cancer. The correlation between both lung cancer and nanotechnology in modern day medicine, is believed to be very beneficial to patients and doctors

Nanotechnology has become something of a buzzword in recent times. This is primarily due to it being a new and emerging science, but also because of its amazing applications and uses. Nanotechnology encompasses a varied array of subcategories in chemistry, biology, and physics. Generally, it includes all particles which are on the order of 1 billionth of a meter. [1]. As the particles involved are this small, it allows a variety of new technologies as well as new options for the treatment of diseases. Cancer is but one of these few diseases which nanotechnology has presented a new and refreshing chance to find a treatment. Cancer can be defined by anomalous and invasive

Nanotechnology is the development of atoms in a certain object. Nanotechnology has become very popular in the past few years. It is a way to rebuild the systems of life. To make systems move faster than ever before. Nanometer is about 10 times the size of an atom. Each of these has a huge effect on a system. Still there are questions out there that keep people wondering how important nanotechnology is to us. Many wonder how will it affect them and if we should continue this research. I myself wondered about nanotechnology. After researching this topic I have learned new and interesting facts to help me understand the entire concept.

There are always pros and cons to everything, especially technological innovations. An example of this can be seen in the second wave of technology according to Alvin Toffler in his book, “The Third Wave”, where everything was used or produced or created in a massive scale –even the infamous weapons of mass destruction. Yes, everything became bigger. Travel was faster. Doing tasks became easier with the help of machines. But of course, there is always another side to things and those are the cons. By producing more stuff, people also craved for more as well. By producing massive amount of things, the resources needed for production were also massive. This demand branched out to more problems. As we can see, technological innovations will not just bring solutions but also problems. That is just the way things work. Nothing’s perfect. It is just a matter of weighing the advantages and the disadvantages of things.

Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers (SPI, 2015). The field of nanotechnology is growing and one of the most popular areas for current research and developing in a number of different disciplines. It covers a broad range of topics, like polymer-based nanomaterials, nanoparticle drug delivery, self-assembled polymer films, nanofibers, polymer blends and nanocomposites. Nanotechnology is not new to polymer science as studies before the age of nanotechnology involved nanoscale dimensions. It is particularly focused on the nanometer length scale (D.R.Paul, 2008).

Nanoparticles or nanomaterials are materials including particles or constituents that are of nanoscale proportions, or something that has been produced via nanotechnology. Biologically hazardous or environmentally toxic reducing agents are normally associated in the nanoparticles chemical synthesis. Today, the growth of eco-friendly and reliable methods for the production of nanomaterials is a vital facet of nanotechnology. One such approach that has shown potential beyond measure is centred on the use of biological micro-organisms, such as fungi for the biosynthesis of these nanoparticles.

A nanoparticle is the most basic component in the construction of a nanostructure. In general, the size of a nanoparticle spans the range between 1 and 100 nm. The properties of many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than larger particles which causes them to be more reactive than other molecules. Self-assembly refers to the process by which nanoparticles or other distinct components spontaneously organize due to direct specific interactions and/or indirectly, through their environment. Self-assembly is typically linked with thermodynamic equilibrium, the organization of the structures characterized the minimum of the system’s free energy. An important aspect of self-assembly is that the building blocks organize into macroscopic structures. This can happen through direct interactions (Interparticle forces) or through indirect interactions like using a template or external field as a guide.

Nanotechnology has offered solution for many problems associated with vast range of applications in different field, such as in medicine, electronics, energy applications, industrial applications, environmental science and many others. In medicine, nanomaterials are used for targeted drug delivery, imaging and sensing applications. It is
