Introduction
Materials with sizes between 1 and 100 nm are known as nanoparticles, and they have special qualities not seen
in bulk materials. Particularly noteworthy are the optical, electrical, and catalytic properties of silver and
gold nanoparticles.
Because of their small size, nanoparticles display qualities like a high surface area-to-volume ratio, quantum
effects, and distinctive optical characteristics.

Green Synthesis Principles
Green synthesis is the process of creating nanoparticles with non-toxic, eco-friendly materials and
procedures. This strategy reduces any health hazards and the impact on the environment. An important
advancement in the synthesis of nanoparticles is green synthesis, which provides a way forward for more
ecologically friendly and sustainable practices. Green synthesis uses renewable resources, energy-efficient
procedures, non-toxic chemicals, and waste minimization techniques to meet the increasing demand for
sustainable and safe nanoparticle manufacturing. Green concepts will probably be more widely and finely
integrated into nanoparticle synthesis as science and technology develop, which will further help conserve the
environment and scientific advancement.
