“…Synthesized NPs using plant extracts are more advantageous than intracellular synthesis using microorganisms since it does not need complex and specialized processes such as isolation, culture maintenance and multiple purification steps. Due to the above, it has become a major focus leading researchers to develop green methods using different parts of the plant, e.g., from leaf 17 – 19 , peel 20 flower 21 , fruit 22 and root 23 . Many compounds present in the plant extract (e.g., p1olyphenols, ascorbic acids, flavonoids, terpenoids and proteins) play an essential role in the mechanism of metal ions uptake, reduction of precursor salt as well as capping agents and some of them with inherent antimicrobial properties.…”

The scientific community is exploiting the use of silver nanoparticles (AgNPs) in nanomedicine and other AgNPs combination like with biomaterials to reduce microbial contamination. In the field of nanomedicine and biomaterials, AgNPs are used as an antimicrobial agent. One of the most effective approaches for the production of AgNPs is green synthesis. Lysiloma acapulcensis (L. acapulcensis) is a perennial tree used in traditional medicine in Mexico. This tree contains abundant antimicrobial compounds. In the context of antimicrobial activity, the use of L. acapulcensis extracts can reduce silver to AgNPs and enhance its antimicrobial activity. In this work, we demonstrate such antimicrobial activity effect employing green synthesized AgNPs with L. acapulcensis. The FTIR and LC-MS results showed the presence of chemical groups that could act as either (i) reducing agents stabilizing the AgNPs or (ii) antimicrobial capping agents enhancing antimicrobial properties of AgNPs. The synthesized AgNPs with L. acapulcensis were crystalline with a spherical and quasi-spherical shape with diameters from 1.2 to 62 nm with an average size diameter of 5 nm. The disk diffusion method shows the magnitude of the susceptibility over four pathogenic microorganisms of clinical interest. The antimicrobial potency obtained was as follows: E. coli ≥ S. aureus ≥ P. aeruginosa > C. albicans. The results showed that green synthesized (biogenic) AgNPs possess higher antimicrobial potency than chemically produced AgNPs. The obtained results confirm a more significant antimicrobial effect of the biogenic AgNPs maintaining low-cytotoxicity than the AgNPs produced chemically. The field of material sciences encourages to obtain materials of various types of nanoscale shapes and architectures 1 .NPs with a size range of 1-100 nm, and different shapes provide unique chemical 2 , physical 3 and optical properties 4,5. NPs can be synthesized with physical, chemical and biological methods 6. These methods might have unique advantages and disadvantages depending on the end application 7-11. For example, physical methods might have some disadvantages when applied in microbiology. The methods can be time-consuming and constrain to specific requirements like high temperature or pressure, which might result unattractive owing to equipment and associated cost 12,13. A key advantage of chemical methods is the accessibility to get the NPs in

“…The silver nanoparticles synthesized with AgNO 3 and leaf extract of Annona reticulata showed potent activity against Bacillus cereus and Staphylococcus aureus at 125 and 31.25 μg/mL; while it inhibits Escherichia coli , Pseudomonas aeruginosa and Candida albicans at 62.5 μg/mL . Similarly, the s ilver nanoparticles prepared with increased concentrations of Lepidium draba root extract showed that the nanoparticle with reduced size posses strong activity against S. aureus , B. cereus , E. coli, and S. Typhimurium . Again the silver nanoparticles from Caesalpinia coriaria leaf extract are active against antibiotic‐resistant S. aureus , E. coli , Klebsiella pneumoniae , and P. aeruginosa ; while silver nanoparticles of Helicteres isora root extract possess antibacterial with antioxidant activity; similar to our observation with silver nanoparticles of A. lebbeck bark extract but at extremely low concentrations.…”

“…The image also showed the damaged cell wall (pores) and cell membrane leading to the leakage of cytosolic content to lysis, compared to the untreated bacteria with normal rod‐shaped morphology, due to the differences in their sensitivity pattern (MIC 0.50 and 0.60 μM), along with variations in inoculum size, resistance level, peptidoglycan, biochemical and molecular structure as well as other components. Further, nanoparticles not only act on bacteria by direct contact, but also penetrate rapidly to interact with microbial DNA, that prevents the bacterial to develop resistance, and thus nanoparticles are less disposed to bacterial resistance . This suggests that Ag‐NP‐AE can be helpful in the management of those MDR‐bacterial infections.…”

Silver nanoparticles (Ag-NP-AE) are synthesized and stabilized by the extract of an ethnomedicine, Albizia lebbeck bark aqueous extract (AE). Ag-NP-AE is active against several multidrug-resistant (MDR) clinical isolates. The nanoparticles are characterized by UV-vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), Dynamic light scattering (DLS), Scanning electron microscope (SEM), Transmission electron microscope (TEM) and X-ray diffraction (XRD) studies. The antibacterial potency of Ag-NP-AE is determined by Disc diffusion, Agar and Broth dilution assays against 14 MDR isolates along with their minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC). The growth kinetics was determined by quantification of colonies; while toxicity by quantification of viable cells. The Ag-NP-AE shows free-radical scavenging activity at 15-20 μM and is nontoxic up to 50 μM but demonstrated significant antibacterial activity against all the test isolates with zone diameter of 10.4-19.5 mm and MIC of 0.5-0.84 μM (0.085-0.143 μg); while the zone diameter with AE was 10.2-15 mm and MIC of 128-1024 μg/mL, respectively; while 100 % killing was observed at 0.50 μM within 2-4 h of exposure due to damage of cellular architectures.

“…The medical properties of gum are the use of it as a carminative, mild diuretic, diaphoretic, expectorant, stimulant, vasodilator, and antimicrobial agent. It is listed in the British pharmacopoeia as an expectorant and antispasmodic drug; occasionally, it is also used for chronic bronchitis and persistent coughs [42].…”

Silver nanoparticles (SNPs) were synthesised by using the Arial part extract of . and characterised by employing UV-visible spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction techniques. Transmission electron microscopy and field emission scanning electron microscopy were applied to investigate the morphological structure of the bio-synthesised SNPs. The antimicrobial activity of SNPs was studied against Gram positive ( and ) and Gram-negative ( and ) bacteria by employing the disk diffusion agar process. An extremely antimicrobial effect was observed for SNPs. Utilising as a mediator for the synthesis of SNPs helped to save time and cost.
