Nanotechnology is the engineering of functional systems at the molecular scale. The study and building of matter and molecules is involved. This happens at the scale of 0.1 to 100 nanometers. A nanometer is a type of measure and an idea of is its equivalence would be a strand of hair which is 50 000 nanometers in terms of diameter and a nylon fibre which 30 000 nanometers. This should give a clear picture of how small a nanometer is. Particles of a few to or hundreds of nanometers in terms of diameter
Quantum Physics comes to our mind first. In Nanotechnology, we deal with objects of size of less than 100 nanometer, so Quantum Physics provides the basis for Nanotechnology. No one can ignore the importance of Quantum Physics when dealing with Nano scales. Therefore, here we also discuss wavelike nature of electrons and Standing wave electron energy levels. In this article, we also discuss about the Focused ion beam mechanics, its advantages and disadvantages. 1.1 Introduction: Nanoscience is the science
Nanotechnology has potential to solve problems related to human civilizations pertaining to both basic needs and aspirations for comfort life. The basic needs of human being are food, drinking water, energy, cloth, shelter, health and clean environment. The aspirations for comfort life are realizing the automation in every field, space travel and expanded life-span and so on. Due to continuous efforts of scientists and engineers during last 30 years, there is a substantial progress in realizing the
world, nanotechnology is used in the preparation of smart drugs. These drugs help people to get cured faster and without the side effects that other traditional drugs have. Nowadays, nanotechnology in medicine is focusing on research areas like tissue regeneration, bone repair, immunity and for curing ailments like cancer, diabetes, and other life threatening diseases. Disadvantages of Nanotechnology The disadvantages of nanotechnology are listed below. · Due to the development of nanotechnology, many

In this paper we will focus on how Nano Science is very effective in all fields of our life communications, medical science, computing and all products we use in everyday life (Nano electronics devices) like laptops , smart phones , tablet s... Nanotechnology is a new field of science and engineering that focuses on studying and making very, very small things. To fully understand the word Nano electronics we can divide it into two terms the first term is Nano which means a very small something that
2016-2017 SUBMITTED BY:- HARSHIT MEHTA 16BME0756 SUBMITTED TO:- MRS.BARNALI MAITI Abstract:- Nanotechnology increases the strengths of many materials and devices, as well as enhances efficiencies of monitoring devices, remediation of environmental pollution, and renewable energy production. While these are considered to be the positive effect of nanotechnology, there are certain negative impacts of nanotechnology on environment in many ways, such as increased toxicological pollution on the environment
world is getting more complex until the level of technology has increases rapidly years by years. There are smarter and genius people keep doing research to achieve their goals and make the life easier and better. So, in some senses, the term ‘nanotechnology’ is not a new thing in this millennium era as it already existed since 1959. Basically, nano- is one of SI prefix which means a billionth of a meter. To compare a size of nanometer to a meter is like a size of football to a size of the earth.
ingredients. Incorporation of bioactive compounds– for example, vitamins, probiotics, bioactive peptides, and cell reinforcements etc.– into food system give a straightforward approach to create novel functional foods that may have physiological advantages or lessen the dangers of diseases. Some of these are essential for human wellbeing (vitamins and minerals), whereas others provide health benefits beyond the basic nutrition (nutraceuticals). The incorporation of these bioactive into the food products
