ABSTRACT
The field of nanotechnology is wide and crosses several disciplines, including physics, biology, engineering, and chemistry. Sonochemical decomposition, chemical reduction, thermal decomposition, microemulsion, polyol technique, microwave, laser cutting, and many other methods are used. Characterizing the shape, morphology, and size of metal nanoparticles (NPs) is a vital step in the synthesis of metal NPs. The major precursor material in the manufacture of metal NPs is metal. The localized surface plasmon resonance (LSPR) characteristic was considered a unique optoelectrical feature in these NPs. Magnetic nanoparticles are manufactured from a wide range of compositions and materials, each with unique physical and magnetic properties that are important for their anticipated uses. Quantum dots (QDs) are semiconductor nanoparticles with optical and electronic capabilities that are size- and composition-dependent. The antimicrobial properties of metallic NPs are frequently employed, like the use of silver NPs in implants, bone cement, and wound coverings.
