The And Its Effect On The Nanoscale

Nanoparticles (1 000 000 times smaller than a millimetre) are manifesting to be a great success in nanomedicine’s discovery of supplementary methods of fighting against superbugs. At the University of Colorado, researchers have utilized nanoscale quantum dots, which are “miniscule semiconductor particles with specific light-absorption properties, to kill drug-resistant superbugs without harming the surrounding healthy tissue,” (Nagpal, 2017: para. 2). Nanoscale quantum dots that are activated by a light source perturb the balance of chemical processes in threatening bacteria that would kill them.

Silver impregnated dressings have been used extensively over the past few decades in the management of chronic wounds and burns. Before the 1800s, Silver was used for the treatments of ailments such as seizures, leg ulcers, skin infections, partial burns, surgical wounds, perinanal abscesses, disinfection of fluid and sexually transmitted diseases. By mid 1900s, the use of Silver started to expand and was used in different forms such as dressings, eye drops, powder and so on. Silver nitrates were also used as antibiotics to prevent eye infections after deliveries, MRSA, Staphylococcus aureus, B-hemolytic streptococci, Pseudomonas aeruginosa and Escherichia Coli (Castellano et al, 2007, pp. 114-115). Nevertheless, adverse effects were not monitored.

Silver nitrate AgNO3 (≥99.0%) and PVP (Average molecular weight ~55,000) were purchased from Sigma-Aldrich. Ethylene glycol (EG) and Hydrochloric acid (HCl) were purchased from Merck specialities Pvt Ltd. All the chemicals were used as received without any purification. We synthesized silver nanocubes (Ag NCs) by a typical polyol method. In a typical synthesis, 12.5 mL of ethylene glycol was poured in 50 mL of round bottom flask and heated at 140°C for 1 h under stirring. An amount of 2.5 mL of HCl solution (3.3mM in EG) was quickly injected into the reaction mixture. After 10 min, 7.5 mL of AgNO3 solution (94mM in EG) and 7.5 mL of PVP (147mM in EG) solutions were simultaneously injected into the stirring solution. The reaction mixture was

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

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.

Nowadays, much attention has been devoted to the use of Ag in treatment of cancer. As well as gold, silver is known as a good electrode material with high electrical conductivity and has the ability to self-assemble. Furthermore, for Ag nanoparticles on a conducting surface, we can expect some biocompatibility different from Au nanoparticles and the excitation of surface enhanced Raman scattering.

Nanotechnology is the gateway to near limitless possibilities for the human race. It opens the window to a new realm we previously have never experienced-- Nanotechnology is a branch of engineering that deals with the manipulation of atoms at the molecular level. The Institute of Nanotechnology in the U.K. expresses it as "science and technology where dimensions and tolerances in the range of 0.1 nanometer (nm) to 100 nm play a critical role”. Once automated, the nanoparticles will infiltrate every aspect of our lives- from medical, engineering, biomaterials energy production, to name a few. Practically everything we use today could be replaced by nanomaterial in some way, and it even has the capability to create new materials.

In recent years Nano sized materials play the significant role in science and technology due to their unique shape, size, peculiar properties and potential applications. Metal nanoparticles, which possess considerable electronic, chemical and optical [1, 2] properties, are different from those of the bulk materials. Among the several metal nano particles gold (Au) nanoparticles have attracted rigorous consideration for their numerous applications in catalytic , sensing, imaging, diagnostics [3-6], tunable surface Plasmon resonance, surface enhanced Raman scattering, electrical, magnetic, thermal conductivity chemical and bio stability and anti-bacterial activity [7-13]. Besides, Gold nano particles have widely been used as the platform

Nanosilicates have their unique surface charge and shape. This encourages very strong interactions with the gelatin collagen-based matrix. Eventually, it will form structures which it can assembly itself. These structures can form and break dynamically which results in shear-tinning characteristics. [Janet R. Xavier et al. February

Nanotechnology is one of the most advanced and well reputed branches of modern sciences. Nanotechnology is handling of matter at the atomic or molecular level. Scientists from all over the world are now considering forthcoming effects of nanotechnology on human and environment. Nanotechnology is likely to be crucial to the 21st century scientific and medical advancement and its developments will be determined by the collective hard work of natural, physical, medical, engineering and related sciences. The materials in Nano scale can show different properties compared to what they exhibit on a macro scale. A nanoparticle by definition is, an ultra-refined particle that has all the dimensions in the Nano range i.e. from 1nm to 100

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).
