| Summary: | Aqueous extract of Clinacanthus nutans leaves were used as a biological source for the reduction of
silver nitrate into silver nanoparticles. Result obtained from UV-Visible analysis exhibit the absorption
peak at 460 nm confirms the production of silver nanoparticles. FTIR analysis showed the presence of
alkyne, alcohol and primary amine that are responsible for reduction and stability of nanoparticles. The
size of silver nanoparticles based on TEM analysis showed size from 6.26nm until 26.77nm and are in
spherical shape. These nanoparticles showed good antibacterial activity and good synergistic effect in
combination with different antibiotics such as amikacin, rifampicin, ofloxacin, moxifloxacin, piperacillin
and levofloxacin against Escherichia coli, Klebsiella pneumonia and Staphylococcus epidermidis were
studied. |
