These monitoring confirm the potential that lipidemic, glycemic, antioxidant, free
radical scavenging, and antimicrobial activities act to reduce and as well as stability
agents in silver nanoparticles (Ningappa et al. 2008). Thus, antioxidants tocopherol,
carotene, and lutein are vital in the synthesis and stabilization of silver nanoparticles (Devatkal et al. 2012). Silver NPs are synthesized on the biomolecules surface
without any conglomeration. In addition to the initial visual monitoring of colour
change, their other characteristics have led to more characteristics of the biosynthesized silver NPs. The UV-visible spectra exhibit a sharp band of SPR at the peak of
420 nm, indicating that spherical and relatively small silver NPs.
According to Ovais et al. (2017), the reduction of Ag ions to Ag atoms occurred
with the involvement of phytochemicals found in the plant leaves extract, nanoparticles released found with these biochemical compounds. Recently, Swamy et al.
(2015) claim that functional groups on the surfaces of biochemist’s work on reducing ions. The mechanism indicates that different biochemical groups that existed to
be associated with plant extract have function in reducing ions into nanoparticles.
Ahmad et al. (2010) suggest that different roles are played using various compounds
or molecules of diverse plants in the synthesis of metallic nanoparticles and proposed
a generic mechanism for synthesis of metal nanoparticles by plant extract.
3.4.3 Modification of Nanoparticles Using Laser Irradiation
The expectations of the technical revolution are related to nanotechnology, but the
formation, modification, and use of objects of smaller dimensions in research and
science are gaining so much credence (Köhler and Fritzsche 2008). The functional
properties of nanoparticles make them more ideal as different blocks to build structures of high dimensions of technological significance. In this material, particles act
also on known molecules and are organized into thin films, monolayer, and super lattices for nanoscales. The change in the molecular length makes it potential to include
quantum transformations and transfers from non-conductor to conductor, leading to
compressive electronic and photovoltaic properties (Wang 2000).
Laser ablation can be used for a solid purpose in a liquid medium to manufacture
nanostructures with different compositions (e.g. metals, metal oxides, alloys, hydroxides) as well as various morphological forms, for example nanotubes, nanorods, and
nanocomposites. The manufacture of nanostructures using laser radiation in liquids
is easy and green process that can be executed in normal conditions in organic or
water fluids. Laser ablation in liquid has prepared a series of nanoscale materials
with morphologies, microscopic structures, and distinctive phases in order to search
for new properties (Zeng et al. 2012). Nanomaterials have been manipulated by laser
irradiation extensively in the past using different methods used for melting, fragmenting, or reshaping nanoparticles. It is reported that laser beam radiation either
results in particle fragmentation or fusion due to the melting of photovoltaic heat
(Zamiri et al. 2011). This can be considered an opportunity to use lasers to control
the shape and size of nanoparticles. Additionally, there is a possibility to manufacture
