“…76 Saponins enhance the activities of various antioxidant enzymes such as catalases and superoxide dismutase, which is usually lowered in hyperglycemic conditions. 77 The various plant extracts are cost-effective, safe, and environmentally benign for the creation of NPs, 78,79 So in the present project KE-AgNPs were successfully synthesized from KE extract via green processing. Standardizations was done for the biosynthesis of KE-AgNPs in terms of extract concentration, AgNO 3 salt molarity, temperature, time, stability period, and pH value.…”

Diabetes mellitus (DM) is one of the most prevalent, fatal, and non‐contagious diseases. Therefore, researchers are making attempts to develop novel anti‐diabetic drugs using various organic compounds and biomolecules. The idea of using nano‐materials as anti‐diabetic agents seems interesting. The current study aims to develop Kickxia elatine (KE) extract‐based nano‐silver (KE‐AgNPs) and to evaluate their in vivo anti‐diabetic potency in female Sprague Dawley rats. KE‐AgNPs were characterized using UV spectroscopy, X‐ray diffractometer (XRD), scanning electron microscopy (SEM), Electron Diffraction X‐ray Spectroscopy (EDX), and Fourier transforms infrared (FTIR) techniques. The crystalline nature of KE‐AgNPs with a size of 42.47 nm is confirmed by XRD screening. Spherical‐shaped mono‐dispersed KE‐AgNPs with a mean size of 50 nm are validated by SEM examination. The different phyto‐compounds (tannins, alkaloids, flavonoids, proteins, saponins, phenols, carbohydrates, quinones, sterols, fats, and oils) that contribute to the stabilization and reduction of KE‐AgNPs are confirmed by FTIR analysis. EDX showed a strong peak (3.2 keV) that identified Ag as the main component with a 61.67% contribution. The use of Alloxan to induce diabetes resulted in elevated levels of blood sugar, HbA1c, liver, and lipid profile, as well as a drastic reduction in body weight, body organ weight, and Hemoglobin. These modifications were switched following 21 days of treatment of diabetic rats, and a dosage range of 150–450 mg kg−1 BW of KE extract and KE‐AgNPs demonstrated significant inhibition as compared with the diabetic untreated group. The phytochemical analysis of the KE plant was also assessed to examine the phyto‐compounds involved in the anti‐diabetic potential of KE extract and KE‐AgNPs. These findings suggested that, in comparison with the KE extract, KE‐AgNPs have demonstrated promising anti‐diabetic action.

This study describes a simple, cost-effective, and eco-friendly method for synthesizing silver nanoparticles using a rosmarinic acid extract from Perilla frutescens (PFRAE) as the bioreduction agent. The resulting nanoparticles, called PFRAE-AgNPs, were characterized using various analytical techniques. The UV–Vis spectrum confirmed the formation of PFRAE-AgNPs, and the FTIR spectrum indicated the participation of rosmarinic acid in their synthesis and stabilization. The XRD pattern revealed the crystal structure of PFRAE-AgNPs, and the TEM analysis showed their spherical morphology with sizes ranging between 20 and 80 nm. The DLS analysis indicated that PFRAE-AgNPs were monodispersed with an average diameter of 44.0 ± 3.2 nm, and the high negative zeta potential (−19.65 mV) indicated their high stability. In the antibacterial assays, the PFRAE-AgNPs showed potent activity against both Gram-positive (Bacillus subtilis and Staphylococcus aureus) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacterial pathogens, suggesting that they could be used as a potential antibacterial agent in the clinical setting. Moreover, the antioxidant activity of PFRAE-AgNPs against DPPH and ABTS radical scavengers highlights their potential in the treatment of various oxidative stress-related diseases. PFRAE-AgNPs also demonstrated significant anticancer activity against a range of cell lines including human colon cancer (COLO205), human prostate carcinoma (PC-3), human lung adenocarcinoma (A549), and human ovarian cancer (SKOV3) cell lines suggesting their potential in cancer therapy. The nanoparticles may also have potential in drug delivery, as their small size and high stability could enable them to cross biological barriers and deliver drugs to specific target sites. In addition to the aforementioned properties, PFRAE-AgNPs were found to be biocompatible towards normal (CHO) cells, which is a crucial characteristic for their application in cancer therapy and drug delivery systems. Their antibacterial, antioxidant, and anticancer properties make them promising candidates for the development of new therapeutic agents. Furthermore, their small size, high stability, and biocompatibility could enable them to be used in drug delivery systems to enhance drug efficacy and reduce side effects.

“…Metal-based nanoparticles (MNPs) are produced from metals in nano sizes. Highly electrically charged surfaces, different types of shapes, reactive properties, small pore sizes, colors, and responsiveness to natural factors like temperature, air, and solar radiation are just a few of these nanomaterials' distinctive qualities [20,21]. Among multifunctional nanoparticles, bimetallic nanoparticles (BMNPs) are the right mixture of two distinct metals with improved reaction characteristics [22].…”

Today, there is the roar of sustainable material development around the globe. Green nanotechnology is one of the extensions of sustainability. Due to its sustainable approach, the green fabrication of nanoparticles has recently surpassed their classical synthesis in popularity. Among metal nanoparticles, contemporary findings have demonstrated that bimetallic nanoparticles possess more potential for different applications than monometallic nanoparticles due to the synergistic effects of the two metals. So, we are presenting facile, one-vessel, and one-step phyto-fabrication of Ag–Fe BMNPs using the bud extract of Syzygiumaromaticum. The synthesized nanoparticles were characterized by UV-VIS, XRD, EDX, FTIR, and SEM. The synthesized NPs and the extract underwent biological studies. The radical scavenging potential of the NPs and the extract was found to be 64% and 73%, and the insecticidal potential was found to be 80% and 100%, respectively. Similarly, the NPs and the extract both exhibited good antibacterial activity. The zone of inhibition using 100 mg/mL of extract and NPs was found to be 1 cm against all bacterial species, i.e., K. pneumonia, E. coli, and S. aureus. It was 1.5 cm, 1.3 cm, and 1 cm against K. pneumonia, E. coli, and S. aureus, respectively, showing that the antibacterial activity of the extract is higher than that of the NPs. So, this study unlocks the synthesis of Ag–Fe bimetallic nanoparticles using eco-safe, cost-effective, facile, and least-harmful green methodology with potential applications of both NPs and SA extract in medical and agricultural fields, a step towards sustainability.
