PENGARUH VOLUME DAN WAKTU BIOSINTESIS PERAK NANOPARTIKEL MENGGUNAKAN EKSTRAK BUNGA TEMBELEK AYAM PUTIH (Lantana camara) DENGAN METODE SONIKASI DAN APLIKASINYA SEBAGAI ANTIOKSIDAN
Abstract
Many recent studies have indicated the potential of silver nanoparticles
(AgNPs) for some medical applications such as cancer detection, cancer
treatments. Nanoscale materials such as metal nanoparticles are currently being
employed for more excellent activity of metals. Due to its development, the
method to obtain metal nanoparticles is widely studied, one of these is within the
green synthesis scheme, i.e. the use of plant extract as bioreductor. In this paper,
the use of shrub; white Lantana camara flower as bioreductor in silver NPs
synthesis was conducted.
Bioreductor of white Lantana camara extract was prepared by refluxing of
dried Lantana camara flowers. The extract was mixed with Ag solution followed
by sonication. The nanoparticle formation was measured by using UV -Vis
spectrophotometry, FTIR and PSA. The nanoparticle solution was tested for
antioxidant activity by DPPH method and its measurement by u sing UV-Vis
spectrophotometer.
The result indicates that the extract of white Lantana camara is potential
to be used as bioreductor in silver nanoparticle synthesis. The nanoparticles are
found to have particle size in between 76.7-93 nm. Silver nanoparticles are well as
antioxidant. The antioxidant activity of derived nanoparticles is between 15-61%.
