Abstract:
In recent science, Nanotechnology is a burning feel for the research. Nanotechnology deals
with the Nano particles having a size of 1-100 nm in one dimension used significantly
concerning medical chemistry, atomic physics and all other known fields. Nano particles are
use extremely due to its small size, orientation, physical properties, which are reportedly shown
to change the performance of any other materials which is in contact with these tiny particles.
These particles can be prepared by different chemical, physical and biological approaches, But
the biological approach is the most emerging approach of preparation. The use of seeds and
their extracts is one of the most valuable methods which are gaining concerns due to their
imperative biological benefits. Plants are not only beautiful but majestic because they are rich
sources of various medicinally important substances. Here in the present work “synthesis of
selenium nano particles” described. The Se NPs are formed by simple mixing of Cumin seeds
extract and selenious acid (H2SeO3) solution. This mixture was stirred which gave a dispersion
of Se NPs conjugated with Cumin secondary metabolites. The formation of Se NPs was
observed by the change of colour from colourless to dark brown. The work was focused to
determine the synthesis, its characterization and its applications. The suspension solution confirms the
formation of Se NPs showed (310 nm) by UV analysis. The green synthesized Se NPs were
characterized by UV–VIS, FTIR and XRD analyses. Biological synthesis involves the use of
cumin seeds extract in the universal solvent namely water. The reaction process was simple
and convenient to handle, and was monitored using ultraviolet visible spectroscopy (UV–VIS).
The results were promising and rapid in the production of selenium nano particles
