WHAT IS SO SPECIAL ABOUT NANO PARTICLES?
Nanoscience and nanotechnology came into their own as research fields in the very early 2000s when the potential of the fields was better known. They became a national research priority in the USA. The development and applications of the technology has been widespread and ongoing since then.
Nanoparticles (NPs) are small materials having size spans from 1 to 100 nm. They can be categorised into different types based on their properties, shapes, or sizes. The types of nanoparticles include fullerenes, metal NPs, ceramic NPs, and polymeric NPs. Nanoparticles have unique physical and chemical properties due to their high surface area and nanoscale size. Their unique properties make them suitable for various commercial and domestic applications including medical applications, energy-based research, and environmental applications. However, heavy metal nanoparticles of lead, mercury and tin are identified to be very stable. Therefore, these are not easily degradable, and this may lead to environmental issues.
Due to their size, nanoparticles (NPs) have unique material properties. Fabricated nanoparticles have many applications in sectors such as medicine, engineering, catalysis, and environmental remediation.
According to their size, morphology, physical and chemical properties, nanoparticles are classified into carbon-based nanoparticles, ceramic nanoparticles, metal nanoparticles, semiconductor nanoparticles, polymeric nanoparticles, and lipid-based nanoparticles.
Nanoscience has been finding an increasing variety of applications, and that trend is almost certain to continue for many years to come.
