Objectives: This study, therefore, evaluated CT extract-based silver nanoparticles (Ag NPs) for their antioxidant and anti-inflammatory potential. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; The nanoparticles were prepared using green synthesis methods. They were characterized using UVVis spectroscopy, scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). Antioxidant study was based on NO, H2O2, superoxide, and hydroxyl radical scavenging spectrophotometric methods. The&lt;em&gt; in vitro &lt;/em&gt;anti-inflammatory test was based on a protein (egg albumin) denaturation assay. &lt;strong&gt;Results: &lt;/strong&gt;Results showed CT-Ag NPs ranged from spherical to cubic shapes. The UV absorption peak at 427 nm suggests CT-Ag NP formation. The presence of elemental Ag (96.04 %) by EDX analysis suggests the conversion of metallic silver into elemental silver. The crystallinity of the nanoparticles was shown on the X-ray diffractogram as a sharp peak at 38.12° [reflection index (111)] with an average particle size of 47 nm. CT-Ag NPs showed dose-dependent hydroxyl and nitric oxide radical scavenging activities with 67.63 ± 0.78 % and 58.48 ± 1.20 %, respectively, at 200 μg/mL. It showed a notable anti-inflammatory effect by inhibiting protein denaturation with an IC50 of 53.58 ± 17.78 μg/mL.&lt;strong&gt; Conclusions: &lt;/strong&gt;It can be deduced from this study that CT-Ag NPs show promise as antioxidant and anti-inflammatory agents.&lt;/p&gt;

Antioxidant, anti-cancer, and DNA cleavage activities were based on standard&lt;em&gt; in vitro &lt;/em&gt;bioassay methods. &lt;strong&gt;Results: &lt;/strong&gt;The UV-vis absorption peak at 430 nm suggests the formation of silver-based NPs. The FESEM imaging showed spherical-to-cubical shaped MY-Ag NPs with an average size of 45.35 nm. The EDX analysis showed the presence of elemental Ag (89.40%) and N (10.22%), suggesting a successful synthesis. The XRD analysis revealed various peaks at 38.37⁰, 43.56⁰, 63.76⁰, and 77.77⁰, which suggest metallic silver reflections, further establishing the crystallinity of NPs. The MY-Ag NPs inhibited O&lt;sub&gt;2&lt;/sub&gt; -, OH-, H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt;, and NO free radicals in a dose-dependent manner. At 50 and 80 μg/mL, it demonstrated a better inhibitory effect on OH- radical than &lt;em&gt;L&lt;/em&gt;-ascorbic acid. The cytotoxicity (IC&lt;sub&gt;50&lt;/sub&gt;) against human cancer cell lines of the kidney (ACHN) and the liver (HepG2) were 54.21 ± 0.06 μg/mL and 33.36 ± 2.25 μg/mL respectively at 48 h post-treatment. Lastly, at 20 mg/mL for 120 minutes, MY-Ag NPs cleaved DNA, acting as chemical nucleases. This may suggest its capacity to impede cancer cells by cleaving the genome. &lt;strong&gt;Conclusion: &lt;/strong&gt;Therefore, this study has shown that Myricitrinbased Ag NPs possess notable antioxidant and cytotoxicity that can be further exploited in the search for newer anticancer agents.&lt;/p&gt;

Objective: This study, therefore, utilized a flavonoid glycoside, Myricitrin (MY), isolated from &lt;em&gt;Eugenia uniflora &lt;/em&gt;as a biogenic substance for the synthesis of zinc oxide nanoparticles (ZnONPs) and evaluated the antioxidant, anti-hyperglycaemic, and anti-inflammatory potentials. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Flavonoid glycoside was isolated from the leaf of &lt;em&gt;E. uniflora&lt;/em&gt; following standard phytochemical techniques for extraction, solvent-partitioning, column chromatography, and thin-layer chromatography. The phytocompound was characterized by NMR and HRESI-MS methods. Zinc oxide NPs were green synthesized using the isolated flavonoid glycoside. The biogenic ZnONPs were characterized using UV-Vis, FESEM, EDX, and XRD techniques. The biological potential of the MY-ZnONPs was based on in vitro analysis. Nitric oxide (NO), H2O2, OH, and O2 - antioxidant methods were used. The anti-hyperglycaemic effect was based on α-amylase and α-glucosidase enzyme inhibition, while the egg albumin denaturation (EAD) method was used to determine the antiinflammatory effect. &lt;strong&gt;Results:&lt;/strong&gt; Flavonoid glycoside was isolated and characterized as myricitrin from &lt;em&gt;E. uniflora&lt;/em&gt;. The MY-ZnONPs were green synthesized as a greyish powder. The UV-Vis absorption peaks at 387 and 415 nm match the characteristic peaks for ZnONPs. The FESEM revealed petal-, irregular-, and spindle-shaped NPs of 30-80 nm size, which tend to agglomerate in clusters and bundles. The EDX analysis showed the elemental weight percentage of Zn and O to be 79.83% and 18.51%, respectively, indicating the successful formation of ZnO nanoparticles. The X-ray diffractogram showed the crystallinity of the NPs at 29.23⁰, 36.25⁰, 51.50⁰, 63.67⁰, 72.06⁰, and 78.90⁰. At 100 μg/mL, the NPs demonstrated a comparable 68% inhibition of O&lt;sub&gt;2&lt;/sub&gt; - to Quercetin, the standard antioxidant. They inhibited EAD in a dose-de pendent manner, having ≥75% inhibition at 200 μg/mL. Finally, they exhibited notable anti-hyperglycaemic properties against α-amylase and α-glucosidase with IC&lt;sub&gt;50&lt;/sub&gt; of 89.24±0.63 and 105.95±0.05 μg/mL, respectively. &lt;strong&gt;Conclusion:&lt;/strong&gt; This study has shown MY-ZnONPs as a flavonoid glycoside-based metal oxide nanoparticle with notable antioxidant, anti-diabetic, and anti-inflammatory activities.&lt;/p&gt;

Nigella sativa L. (black Cumin) seed infusions are useful in Asian and African ethnomedicines in remedying stress and inflammatory-related ailments. &lt;strong&gt;Objective: &lt;/strong&gt;On this premise, black Cumin-based silver nanoparticles (BC-Ag NP) were developed and evaluated for their biological potential. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Silver nanoparticles (AgNPs) were green synthesized using the seed aqueous extract of black cumin (BC). The BC-AgNPs were characterized using scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM), highresolution transmission electron microscopy analysis (HRTEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). The biological potential of the NPs was based on NO, H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt;, •OH, and O&lt;sub&gt;2&lt;/sub&gt; •– radical scavenging antioxidant, egg albumin denaturation (anti-inflammatory), and DNA cleavage assay methods.&lt;strong&gt; Results: &lt;/strong&gt;The SEM and FESEM revealed spherical-to-cubical-shaped ultrafine BC-Ag NPs with a size of less than 100 nm. The HR-TEM micrograph confirmed each NP to be spherical in shape and within the 10-50 nm range. The X-ray diffractogram showed the crystallinity of the NPs with a sharp peak at 38.12° [reflection index (111)] at an average size of 47 nm. The transformation of metallic silver into elemental silver was validated by EDX analysis, with 97.58% elemental Ag at ~3 keV acute curve. The BC-Ag NPs showed dose-dependent antioxidant activity, with IC50 of 87.56 ± 1.54 and 110.5 ± 2.27 μg/mL against H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt; and O&lt;sub&gt;2&lt;/sub&gt; ._ free radicals, respectively. The anti-inflammatory activity of the NPs was one-third the potency of Diclofenac sodium (standard drug) at IC&lt;sub&gt;50&lt;/sub&gt; of 103.44 ± 5.35 μg/mL. Finally, the BC-Ag NPs acted as chemical nucleases to cleave DNA at a 20 mg/mL concentration for 120 minutes.&lt;strong&gt; Conclusion: &lt;/strong&gt;This study has shown that AgNPs biosynthesized with black Cumin seed extract possess notable antioxidant, anti-inflammatory, and DNA cleavage properties and, thus, may be a useful nanomaterial for efficient pharmaceutical delivery.&lt;/p&gt;

Characterization was based on field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), ultraviolet-visible (UV-Vis) spectroscopy, and energy-dispersive X-ray (EDX) spectroscopy. The anticancer potential of EU-ZnONPs was based on MTT-based cytotoxicity (CC50) against human cancerous (HepG2 and ACHN) cell lines. &lt;strong&gt;Results:&lt;/strong&gt; The FESEM revealed spherical-to-cubical shaped EU-ZnONPs with 40 and 80 nm average size ranges. Further microscopic evaluation by HRTEM showed that the bulk of the nanoparticles (NPs) are spherical, ranging from 5–30 nm in size. The UV-Vis absorption peak at 387 nm agreed with the characteristic 300-400 nm peak range of biogenic ZnONPs. The presence of Zn and O at elemental weight percentages of 73.55 and 23.05% confirmed the successful green synthesis of the Eu-ZnONPs. At 48 h post-treatment, the cytotoxicity against HepG2 and ACHN cancer cell lines was concentration-dependent, with CC50 values of 54.21 ± 0.06 μg/mL and 33.36 ± 2.25 μg/mL, respectively. &lt;strong&gt;Conclusion: &lt;/strong&gt;This study has shown that EUZnONPs possess notable cytotoxicity against HepG2 and ACHN cancer cells, thus suggesting E. uniflora extract-based ZnONPs as a promising anticancer bioresource.&lt;/p&gt;

The BC-ZnONPs were characterized by microscopy (FESEM and HRTEM) and spectroscopy (UV-Vis and EDX) methods. &lt;em&gt;In vitro &lt;/em&gt;anti-hyperglycaemic evaluation was based on α-amylase and α-glucosidase inhibition assays. &lt;strong&gt;Results:&lt;/strong&gt; The BC-ZnONPs showed a spherical-to-cubical shape with a 10-50 nm size range. The UV-Vis absorption peaks at 387 and 415 nm suggest the formation of biogenic ZnO NPs. The EDX spectrum revealed 68.92% and 27.49% weight compositions of Zn and O, respectively, to further substantiate ZnO nanoparticle synthesis. The BC-ZnONPs showed notable anti-hyperglycaemic properties with IC&lt;sub&gt;50&lt;/sub&gt; of 87.72±5.13 and 124.21±15.20 μg/mL against α-amylase and α-glucosidase, respectively.&lt;strong&gt; Conclusion: &lt;/strong&gt;Black Cumin seed extract was a useful biogenic material for synthesizing ZnO NPs. The BCZnONPs showed promising anti-hyperglycaemic properties based on the notable inhibitory activities against α-amylase and α-glucosidase enzymes. Future work may include evaluating the synergistic effects of black Cumin metabolites and ZnONPs, as well as determining the in vivo toxicity profile for safety considerations.&lt;/p&gt;
