Although nanotechnology is still relatively new, some studies have been conducted on possible environmental risks. There are lots of issues involved with nanotechnology, and here we mentioned some of these issues below-. Nanoparticles (NPs) are commonly classified according to morphology, size, and chemical properties in different classes. What are nanomaterials? All of this can add up to a decreased risk to the patient and an increased probability of survival. NANOMATERIALS in Nanotechnology Nanoparticles are the particles that have three dimensional nanoscale, the particle is between 1 and 100 nm in each spatial dimension. It has been reported that inhaled nanoparticles can reach the blood and may reach other target sites such as the liver, heart or blood cells. Nanoparticles such as graphene and carbon nanotubes are among the strongest materials known. Depending on the overall shape these materials can be 0D, 1D, 2D or 3D ( Tiwari et al., 2012 ). Reduced dimensions result in a lower relative precision for external tools, so the accuracy of manipulations has to be realized by the specificity of chemical bonds instead of by external means. Silver nanoparticles are nanoparticles of silver of between 1 nm and 100 nm in size. The goal of Nano Day is to raise awareness of nanotechnology, how it is currently used in products that enrich our daily lives, and the challenges and opportunities it holds for the future.

(Nano literally means. The specific properties of nanoparticles is defined by particle size, chemical composition, crystallinity and shape. Uses of nanotechnology. Nanoparticles are less than 100 nanometers thick. Nanotechnology includes the research and engineering of new materials at the nanoscale level. The nanofabrication is defined as a process, which is used to create and design a new device on the nanoscale. Fullerenes and carbon nanotubes (CNTs) are two elemental carbonbased NP. In nanotechnology, nanomaterials are its main research object and foundation. Nanoparticles are materials that are confined to the nanoscale in all three dimensions. "Nano" comes from a Greek word meaning "dwarf ." In essence, it means "very small." A nanometer is 70,000 times smaller than the thickness of a human hair. Here, it is worth noting that nanoparticles are made up of clusters of atoms/molecules. Everything on Earth is made up of atomsthe food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies. Nanotechnology can also be used to chemically target and eliminate odor-causing molecules. nanoparticle, ultrafine unit with dimensions measured in nanometres (nm; 1 nm = 10 9 metre).
