“…[4] Among these NPs, silver nanoparticles (AgNPs) are gaining an enormous attention of researchers because of their versatile applications in different fields (biomedicine, electrical, thermal, biology, and industrial fields) and unique optical, physical, and chemical properties such as high dispersion in solution and the surfaceto-volume ratio. [5][6][7] Different techniques have been utilized for the generation of AgNPs such as physical, biological, chemical, and hybrid techniques, but most of the approaches are unsuitable for being costly and production of toxic byproducts are environmentally hazardous. [8] Therefore, scientists are focusing on reasonable, cheaper, and ecofriendly green methods for the biogenic production of AgNPs where the bio-extracts are utilized as capping and reducing mediators for the fabrication of AgNPs.…”

This research aims to study the biogenic synthesis and characterization of Hypecoum pendulum extract-induced silver nanoparticles (HP-AgNPs) and to investigate its antioxidant, anti-alpha-amylase, and anti-acetylcholinesterase (AChE) activities. UV spectrometry at 417 nm with an surface plasmon resonance (SPR) peak of 1.54 confirmed the biosynthesis of HP-AgNPs. X-ray diffraction (XRD) analysis demonstrated that HP-AgNPs are crystalline with a 36 nm size. The average size of 80 nm was confirmed by scanning electron microscopy (SEM) analysis. The functional moieties bearing compounds accountable for the encapsulation and stability of HP-AgNPs were assessed by the Fourier transform infrared (FTIR) technique. Energy dispersive X-ray (EDX) demonstrated that silver was the main element (49%) of HP-AgNPs. HP-AgNPs showed the promising antioxidant potential of ABTS (71.57%), diphenyl-1-picrylhydrazyl (DPPH, 69.46%), H 2 O 2 (66.94%), ferric chloride (73.71%), and ammonium molybdenum (65.7%). HP-AgNPs exhibited significant enzymatic inhibition potential with IC 50 of 48.8 ± 4.03 μg/mL (α-amylase) and 51.78 ± 3.16 μg/mL (AChE). Kinetics studies showed that HP-AgNPs produced mixed-type inhibition against α-amylase (K m increased from 40.65 to 131.44%, whereas V max decreased from 4.14 to 9.77%) and non-competitivetype inhibition (V max decreased from 17.05 to 62.03% and K m remain constant) against AChE. Finally, it may be concluded that HP-AgNPs may possess anti-Alzheimer, anti-diabetic, and antioxidant capabilities.

“…The nanoparticles (NPs) may be defined as atomic or molecular scale solid nanometer-sized particles ranging from 1 to 100 nm in size and having unique optical, physical, and chemical properties [1,2]. These NPs are usually synthesized using metals such as gold, zinc, copper, iron, silver, and platinum [3]. Among NPs, silver nanoparticles (AgNPs) have versatile applications in the field of medicine and biology because of outstanding properties such as high dispersion in solution and surface-to-volume ratio [4].…”

Green synthesis of silver nanoparticles (AgNPs) is attaining more attention from researchers over chemical fabrication due to their unique properties such as high dispersion in solution, surface-tovolume ratio, low toxicity, and easy preparation. In this paper, a biogenic synthesis of Kickxia elatinebased-silver nanoparticles (KE-AgNPs) was carried out by using K. elatine plant extract (KEE). The characterization of synthesized AgNPs was done by ultraviolet (UV) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray (EDX), and Fourier transform infrared (FTIR) analyses. XRD screening confirmed the crystalline nature of KE-AgNPs with 42.47 nm in size. SEM analysis confirmed the rounded shape AgNPs with 50 nm in size. FTIR confirmed the various functional groups that contribute to the stabilization and reduction of AgNPs. EDX displayed an intense peak (3.2 keV), presenting that Ag has a chief component with 61.67%. These AgNPs showed a potential antioxidant activity against 2,2'-azino-bis-(3-ethyl) benzothiazoline-6-sulfonic acid (ABTS, 66.9%), diphenyl-1-picrylhydrazyl (DPPH, 72.49%), H 2 O 2 (69.42%), ferricreducing antioxidant power assay (FRAP, 70.04%), and ammonium molybdenum (68.77%) at the highest concentration of 160 μg/mL. Statistical analysis showed that both KEE and their AgNPs inhibit alpha-amylase (α-amylase) in the mixed type mode, i.e., Michaelis constant (K m ) increased (16.62%-55.45% and 49.77%-134.78% for KE-AgNPs) and V max decreased (2.68%-12.98% and 4.44%-11%), respectively. In the case of anti-acetylcholinesterase studies, both KEE and AgNPs revealed a mixed-type inhibition against acetylcholinesterase (AchE), i.e., K m increased (13.53%-101.48% and 10.10%-38.04%), while V max decreased (12.66%-52.47% and 11.91%-41.69%) for KEE and KE-AgNPs, respectively. Therefore, the synthesized AgNPs could be used for various purposes due to their non-toxicity, eco-friendly, and compact ability for therapeutic and diagnostic applications.
