Synthesis of nanoparticles based on plant extract as reduction agent has been discovered extensively due to its environmental friendly approach. In this work, a facile silver nanoparticles is synthesized via incorporation of silver nitrate aqueous solution with Parkia speciosa leaves extract. Centrifugation is introduces to improve the characteristics of nanoparticles. Chemical interactions have identified –OH stretching vibration, C=O and C=C, proving the presence of phenolic, terpenoid and flavonoid capped on silver nanoparticles. The TEM result demonstrates the silver nanoparticles had consistence spherical nanoparticles shape with average particles size (59.96 nm) in accordance with FESEM analysis. The structural analysis by XRD shows the nanoparticles had high degree of crystallinity (97%) and crystallite size (17.95 nm). The optical analysis by UV‐Vis reveals that the nanoparticle produces brown colour solution with high absorption band (465 nm). This proves that Parkia speciosa extract has potential as reduction agent in synthesis of silver nanoparticles.

Green synthesis of nanoparticles has gained significant importance in recent years and has become the one of the most preferred methods. Also, green synthesis of nanoparticles is valuable branch of nanotechnology. Plant extracts are eco-friendly and can be an economic option for synthesis of nanoparticles. This study presents method the synthesis of silver nanoparticles using water extract of Arnicae anthodium. Formation of silver nanoparticles was confirmed by UV-visble spectroscopy, Fourier transform infrared spectroscopy and total reflection X-ray fluorescence analysis. The morphology of the synthesized silver nanoparticles was verified by SEM-EDS. The obtained silver nanoparticles were used to study their antimicrobial activity.

Silver nanoparticles have gained global popularity because of its application in crucial areas such as medical diagnosis/therapy, solar cell development, water treatment, surface coating and cosmetic production. Bacterial synthesis of silver nanoparticles is regarded as eco-friendly due to minimal waste generated while being energy efficient. This study was aimed at synthesizing silver nanoparticles using Lactobacillus specie isolated from Kindrimo under the influence of sunlight irradiation. Lactobacillus delbrueckii subsp. bulgaricus isolated from Kindrimo was identified using morphological and biochemical techniques and confirmed using 16S rRNA gene sequencing. The eco-friendly protocol for the extracellular synthesis of silver nanoparticles was accomplished by treatment of Lactobacillus delbrueckii subsp. bulgaricus extract with silver nitrate solution in the ratio 1:10 under the influence of sunlight irradiation. Synthesized silver nanoparticles were confirmed and characterized using UV-Visible Spectrophotometry, Dynamic Light Scattering, Transmission Electron Microscopy and Energy Dispersion Spectroscopy. The absorbance spectrum preliminarily confirmed the formation of silver nanoparticles by revealing characteristic broad peak at 415nm. Dynamic Light Scattering measurements further confirmed synthesis by showing average particle size distribution of 147nm. Micrograph of Transmission Electron Microscopy revealed that the synthesized silver nanoparticles were polyhedral and spherical in shape with size ranging 1.4 to 8.9nm. The elemental composition of the resultant colloidal solution was shown to contain silver nanoparticles when subjected to Energy Dispersion Spectroscopy. This study proved that the effect of sunlight irradiation on Lactobacillus mediated synthesis of silver nanoparticles is energy efficient and inexpensive.
