This review is provided a detailed overview of the synthesis, properties and applications
of nanoparticles (NPs) exist in different forms. NPs are tiny materials having size ranges from 1 to
100 nm. They can be classified into different classes based on their properties, shapes or sizes. The
different groups include fullerenes, metal NPs, ceramic NPs, and polymeric NPs. NPs possess
unique physical and chemical properties due to their high surface area and nanoscale size. Their
optical properties are reported to be dependent on the size, which imparts different colors due to
absorption in the visible region. Their reactivity, toughness and other properties are also dependent
on their unique size, shape and structure. Due to these characteristics, they are suitable candidates
for various commercial and domestic applications, which include catalysis, imaging, medical applications,
energy-based research, and environmental applications. Heavy metal NPs of lead, mercury
and tin are reported to be so rigid and stable that their degradation is not easily achievable, which
can lead to many environmental toxicities.
