Background and Origin
The progression of Science and technology is developing through every possible ways. The extensive research, interdisciplinary efforts, general consciousness and public awareness has really made science the most “sought after” field. Nanotechnology or nanoscience is the most tentative, conclusive part of experiments in science that has been left for the new generation to succeed over. During some recent decades or so nanotechnology has successfully and presumptuously flourished into an independent segment of study and there has been a cumulative rise in the expectations of people from the scientific community to ordinary public as well. Contemporary scientists and expects comment on the fact that the recent achievements can be considered as the tip of an iceberg and believe that there is much more to emerge. Even enthusiastic people tend to call it a “technology of next century”. As believed Feynman to be the father of nanotechnology and such related sciences, he discloses the significances of this particular technology in his most attended essay called, “There’s plenty of room at the bottom”. Moreover, nanotechnology or nanoscience is being predicted as the technology with the potential to revolutionize our industrial evolution and our daily lives.
What is Nanotechnology?
Nanotechnology is generally the study and application of intense small things and can be used across all the other science and technology fields, such as chemistry, biology, physics, natural philosophies, material sciences, and engineering. Chemistry is the study field of atoms and molecules, the dimensions of these are generally less than one nanometer or within one nanometer, whereas physics simply deals with solids of essentially an infinite array of bound atoms and molecules of dimensions greater than 100 namometer. Thus, maintaining a huge unsystematic conflict between the two regimens, it is conducted at the nanoscale, which is about 1 to 100 nanometers. This nanoscale regime is too small to appropriately define by either quantum chemistry or classical laws of physics or other sciences. It all was started as a process in which scientists are able to manipulate and control individual atoms and molecules to create and set different tools along. Finally it is done by seeing individual atoms by the microscope.
Fundamental conceptual ideas of Nanotechnology and Technology
Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Earth as an universal whole and it’s objects are made of particular atoms—the everyday life we go through, the food we eat, the clothes we wear, the things we deal with and even human and every animated body are made of some particular atoms. The effect of the size dependency of nanoscale is seen on various kinds of properties including optical properties, magnetic properties, melting points, specific heats, electrical properties, surface reactivities, and others relative objects. It is often believed that a nanometer is a bewitching point on the length scale, for this is the point where the properties of material significantly differ from those of atoms as well as bulk materials. The reason behind this so called nano-phenomenon can be narrated by studying the technology beyond it. Something as small as an atom is impossible to see with normal eye. In fact, the atoms are too microscopic that they are not perceivable by the microscopes used in high school science classes. Typically, the works with these atoms need more and more Precised technologies to deal with. And for this reason modern science gets involved into various different and difficult inventions to create relatable nanoscales for their concern. Relatively recent almost thirty years ago they almost invented such developed technology to figure out the microscopic elements. Though modern nanoscience and nanotechnology are quite new a concept, they will obviously figure out more modern attempts in this regard. But nanoscale materials were used for centuries.
Modern uses and Progresses
In medical science nanomedicine is a revolutionary change in modern era. It has a great application in nanomaterials and biological devices. Nanotechnology has provided the possibility of delivering drugs to specific cells using nanoparticles. Medical science becomes more powerful and beneficial by nanomedicine. Recently, scientific data is advancing rapidly and nanotechnology has the potentiality to positively impact on the agrifood sector, it also minimizes adverse problems of agricultural practices on environment and human health, improving food security and productivity. According to the experts, it is possible to fulfill the universal demand of healthy, fresh foods. Through more researches experts might increase the capabilities of electronics devices while they reduce their weight and power consumption by using nanotech. In the services of food packaging the use of modern nanotech can be highly applicable. In case of detecting chemicals like carbon nanotubes, zinc oxide nanowires or palladium nanoparticles, nanotechnology works. Nanotechnology has intricate usages to make space flights. Scientific communities from various related fields are coming accordingly to give a proper shape to a brighter future of science with nanotechnology as the main theme.
Further potentials The recent studies in nanotechnology have concluded with the ideas that it has greater promises for future and the potentials of this field are yet to be explored to the fullest. Today’s scientists and experts are searching a wide variety of ways to deliberately make materials at the nanoscale so that people can take advantage of their enhanced properties such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity. The future potentials of nanotechnology are based upon the exciting science behind the nano-phenomenon. Much deeper insights and detailed studies and researches on this science can further improve general conception of nano-phenomenon, which can be applied later to explore the field comprehensively. More applied researches must be conducted to evaluate the feasibility of using nanotechnology in the disaster management cycle. A brief survey was conducted of relevant and contemporary literature to identify the role that nanotechnology could potentially fill in disaster preparedness. Three primary uses for nanotechnology to build community resilience that stand out as the most practical and eminent are in the areas of building materials, sensors, and medicine. Thus, we can proceed through the process of nanotech in future comprehending its bright, stable future.
