“…On contrary, a very small concentration of AgNPs showed good ZOI against the bacterial strains and hence can be used as therapeutic agent. 273 Recently, Butea monosperma, 277 Syzygium cumini 278 and Diospyros montana 279 bark extract were utilized for the green synthesis of AgNPs and investigate its antimicrobial activity. The resultant AgNPs are displayed prominent cell damage to the various bacterial strains.…”

Biosynthesized silver nanoparticles (AgNPs) are widely used in Pharmacy and Medicine. In particular, AgNPs synthesized and mediated by plant extracts have shown topossess several biological activities. In the present study, AgNPs were synthesized using Picea abies L. stem bark extract as reducing agent. Factors, such as metal ion solution, pH, and time, which play a role in the AgNPs synthesis, were assessed. The synthesized AgNPs were characterized by Ultraviolet-Visible Spectrometry, Fourier transform infrared spectroscopy, and Transmission Electron Microscopy (TEM). Further, the study has been extended to evaluate the antimicrobial and antioxidant activity of AgNPs. The broad peak obtained at 411–475 nm (UV-Vis spectroscopy), and the color change pattern, confirmed the synthesis of AgNPs. TEM results showed spherical or rarely polygonal AgNPs with an average size of 44 nm at pH = 9. The AgNPs showed antioxidant activity and antibacterial effect against human pathogenic Gram-positive and Gram-negative bacteria. The results show that spruce bark extract is suitable for obtaining AgNPs, with antibacterial and antioxidant activity.

“…This color change was due to the reducing metal ions during the course of the reaction. 23 More so, the colour intensity was more intense with an increase in incubation time. Colour intensity observation is mainly because of the surface plasmon resonance excitation (SPR) in the SNPs.…”

“…Sphere-shaped and uniform NPs in the solution have a sole SPR band within the absorption range. 23 Size and shape of green synthesized silver nanoparticles as revealed by TEM analysis TEM was utilized to investigate the shape and size of SNPs and the results showed that most of the biologically synthesized SNPs displayed a uniform round shape and the size ranged between 18.7-26.2 nm, as shown in Figure 3. This result is in accordance with that obtained by Malapermal, 22 who found in their studies that synthesized SNPs were 17 nm in size.…”

Nanotechnology is the science of creating and applying nanostructures or nanomaterials and investigating the relationship between numerous properties of materials on their nanometer unit dimensions. 1 Currently, metal-based nanomaterials have attracted interest in various applications like medicine, biotechnology, and nano-chemistry. 2 Several nanomaterials such as titanium, copper, zinc, alginate, gold, metallic elements as well as silver were used. 3,4 Silver nanoparticles (SNPs) were effectively applied in numerous industries like biomedical, pharmaceutical, textile, agricultural, etc due to their distinctive and particular characteristics, especially antimicrobial activity and non-toxicity. 5 There are different methods of synthesizing SNPs; however, greener and eco-friendly synthesis is the best. It produces non-toxic, efficient, eco-friendly and stable materials. 6-7 Biological synthesis using plants and microorganisms such as bacteria and fungi, as well as algae, has attracted immense attention. By using plant extracts, the metal nanoparticles are synthesized with no impurities, which reduce the venturous solvents and decrease the number of agents and stabilizers. 8-9 Some plant extracts are known to be abundant bioreducing agents which can convert the silver ions into SNPs. 7 Biomolecules such as alkaloids, terpenoids, co-enzymes and phenolic compounds of plants behave as reducing agents by changing
