Nanoscopic objects with an .....
In this paper, we will put forward the vast effect on nanotechnology in various fields. A basic definition of Nanotechnology is the study manipulation and manufacture of extremely minute machines or devices. The future of technology at times becomes easier to predict. Computers will compute faster, materials will become stronger and medicine will cure more diseases .the technology that works at the nanometer scale of molecules and atoms will be a large part of this future, enabling great improvements in all the fields of human presence. Supercomputer no bigger than a human cell. Spacecraft no longer or more expensive than the family car. These are just a few promises of nanotechnology. Nanotechnology is expected to have a revolutionary impact on medicine. A variety of medical processes occur at nanometer length scales. Among the approaches for exploiting developments in nanotechnology in medicine, nanoparticles offer some unique advantages as sensing, delivery, and image enhancement...
Applications of Nanotechnology in Medical Science
International Journal of Bio-Medical Informatics and e-Health, 2022
When applied to materials and technologies, nanotechnology refers to the study and manipulation of these systems at the nanoscale scale (one billionth of a meter). Control over the fundamental molecular structure permits control over the macroscopic chemical and physical characteristics, therefore at these sizes, examination of individual molecules and interacting groups of molecules in connection to the bulk macroscopic qualities of the material or device is vital. Material and devices for use in medicine and physiology must be developed to interact with the body at subcellular (i.e. molecule) scales with a high degree of specificity. This has the potential to transfer into clinical applications that are celland tissue-specific, aiming for maximum therapeutic results with minimal adverse effects. This overview provides an introduction to the fundamental scientific and technological features of nanotechnology, as well as a discussion of its possible medicinal applications.

Nanotechnology and Nanomedicine-Heigh–Ho:The Age of Dwarfs
ERA'S JOURNAL OF MEDICAL RESEARCH
It's a small wonder. Yes, nanotechnology is already touching our lives for better. The recent progress in the field of medicine has been phenomenal. None could have ever imagined that the Nanotechnology would have such a promising and extensive application in medical sciences. Right from developing newer therapeutics and imaging techniques to targeted drug delivery you can name it all. Nanotechnology science is still in its nascent stage with a long way to go. A nanometer is a billionth of a meter. Manipulation of matter on a very small scale is Nanotechnology and its utilization in medicine is Nanomedicine. In fact in recent times no other branch has seen the amalgation of such varied disciplines including physicists, chemists, engineers and biologists. Nanotechnology is still a very nascent science. It needs to grow and as its grows its true virtues and vices would come to fore. At the most now we can say that it has a very promising future. The genesis of nanotechnology can be traced to the promise of revolutionary advances across medicine, communications, genomics and robotics.
Nanotechnology in Hospital & Pharmaceutical
2013
Nanotechnology has changed our lives dramatically and influenced every sector of the research, engineering and also business community. Nanotechnology is a rapidly growing science of producing and utilizing nano-sized parti cles, that measure in nanometer. In other words, nanotechnology is the art of character izing, manipulating and organizing matter systemically, at the nanometer scale, which has created a revolution in science, engineering, technology, drug delivery and therapeu tics. The size of typical accessible structures is in the sub-micrometer range, being wi thin the limits of optical resolution and barely visible with a light microscope. This scale is about 1/1000 smaller than structures that could be resolved by the naked eye, but still 1000 times larger than an atom. Recent developments are addressing the size range below th ese dimensions and because a typical structure size is in the nanometer range, the metho ds and techniques are defined as nanotechnology. There is...
Nanotechnology in Medical Field
International Journal for Research in Applied Science & Engineering Technology (IJRASET), 2023
Nanotechnology is the field of using the technology and science that focuses on using molecular level regulation of matter that are of size range less than 100 nm range. In the field of nanotechnology, there are two primary approaches. The two main approaches are "Top-down" approach and "Bottom-up" approach. With a "Bottom-up" approach, materials and gadgets made of molecules that chemically put themselves together using molecular recognition principles are used. The nano-objects are created from larger entities using "Top-down" approach without atomic-level control. In fact, nanotechnology has been useful in a variety of medical fields, including cardiovascular medicine, oncology and the treatment of other chronic illnesses, as there is a significant need for the creation of pharmaceuticals and because the biological elements of live cells play crucial functions at the nanoscale. Undoubtedly, nanotechnology is being utilised to improve the identification of biomarkers, medication development, drug delivery and molecular diagnostics, all of which may be useful in the treatment of these patients. The importance of nanotechnology in the medical sciences and the reasonable side effects of its use will be highlighted in this paper.
A Study on Materialistic Dimensions and its Applications in Nanotechnology
Nanotechnology is one of the very frontiers of science today. It is an emerging interdisciplinary area of research with important commercial applications Nanotechnology is the engineered convergence of biology, chemistry, and informatics on a nanoscale, that is, involving materials measured in billionths of a meter. Nano-scale materials dissolve in different ways, take on different magnetic and electrical properties, react differently to chemicals, or reflect light distinctly from the way they would at normal size. In 1946, when the first computer Eniac was invented, its size was enormous, but its speed was only one-eighty thousand times slower than that of a current personal computer. The story goes that when it was switched on, the whole Philadelphia city left power. With the development of semiconductors, bringing computers down to palm-size, scientists, at first, skeptical of the possibility of making them any smaller due to limited technology.
Nanomedicine and Prospect of Medical Science
“Nanotechnology is the art and science of manipulating matter at the nanoscale” that implies range of technologies, techniques and processes that changes maneuvering of matter at smallest scale (from 1 to 100 nm2) where unique phenomena of particles enable novel applications. National Science and Technology Council (USA) claim that “Nanotechnology is an enabling technology that will change the nature of almost every human-made object in the next century.”
