A quantum dot is a closely packed semiconductor crystal comprised of hundreds or thousands of atoms, and whose size is on the order of a few nanometers to a few hundred nanometers. Nanotechnologies are the design, characterization, production, and application of structures, devices, and systems by controlling shape and size at the nanoscale. Nanomedicine, the application of nanotechnology in medicine, draws on the natural scale of biological phenomena to produce precise solutions for disease prevention, diagnosis, and treatment. Properties and uses Very small size Nanoparticles are so small that they can enter biological tissue. Another important criteria for the definition is the requirement that the nanostructure is man-made, i.e. The specific properties of such nano objects also offer alternatives to classic transduction methods. The precise nature of nanomaterial behavior depends on the specific material. Beyond characterizing the physicochemical properties of MWNTs from different sources or manufacturers, it is also important to characterize different . . The carbon nanotubes can act as conductor or semiconductor in behaviour but we all know that large carbon (graphite) is good conductor of electricity. Nanomaterials are special for several reasons, but for one in particular - their size. The development of the 'Safe-by-design' concept for nanomaterials is currently under investigation by scientists. The scope of Nanomaterials covers the preparation, characterization and application of all nanomaterials. In the past decades, nanomaterials are growing explosively worldwide as an important product of nanotechnologies owing to their extraordinary physiochemical properties. Energy-absorbing nanomaterials; Nano Energies. Nanotechnology is already broadening the medical tools, knowledge, and therapies currently available to clinicians. The ever-increasing interest in the commercialization of nano sized materials has led to significant growth in the disciplines of nanotechnology and nanomedicine [79, 80].As a consequence of this however, the same nano specific characteristics which make NMs desirable might also influence their toxicity [44, 49].As public and occupational exposure increases there is a real need to evaluate the . It is important to state that the field of hepatic toxicology as a whole is recognising the importance of the inclusion of KCs in test systems with more and more drug induced liver . The basic premise is: rather than testing the safety of nanomaterials after they are put on the market, the safety assessment should be incorporated into the design and innovation stage of a nanomaterial's development. Nanotechnology is a common word these days, but many of us don't realize the amazing impact it has on our daily lives. According to the United States National Nanotechnology Initiative, nanotechnology is "science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers."One nanometer is a billionth of a meter, or 10-9 of a meter. Materials at the nanometer scale may unexpectedly become chemical catalysts and result in . Nanoparticles Types, Properties and Uses. Materials at the nanometer scale may unexpectedly become chemical catalysts and result in . Nanotechnology is an increasingly used term in biology, medicine, and surgery, while developers are discovering new ways to use nanoparticles to their advantage.

In the energy sector, the use of nanomaterials is advantageous in that they can make the existing methods of generating energy - such as solar panels - more efficient and cost-effective, as well as opening up new ways in which to both harness and store energy. Introduction The term "Nanotechnology" was first defined byNorio Taniguchiof the Tokyo Science University in 1974. Finally, nanomaterials have an increased surface-to-volume ratio compared to bulk materials. 2D nanomaterials are better reinforcing agents than 1D or 0D nanomaterials. [78].
