In this study, gold nanoparticles with Eutrema japonicum (AuNPs-E.j.) were synthesized using the butylene glycol extract of plant’s grated stem and Au(III) chloride trihydrate solution. The primary characterization of...
This study reports the preparation and characterization of silver nanoparticles synthesized by mediation plant weed Stachytarpheta cayennensis through solution method. Ultraviolet visible spectroscopy (UV-Vis) determines presence in solution. Infrared (IR) proves organic molecules at particles interface. Powder X-ray diffraction (PXRD) provides phase composition crystallinity. Shape was showed scanning electron microscopy (SEM), energy dispersive (EDX) demonstrated elemental mapping...
The aqueous extract of the leaves Odontonema strictum (OSM) is used in folk medicine for its antihypertensive properties, and it contains a wide range secondary metabolites, mostly polyphenols such as verbascoside isoverbascoside, which could play major role preparation silver nanoparticles. In this study, we aimed to prepare AgNPs first time using OSM leaf (OSM-AgNPs) investigate their free radical-scavenging potency against 1,1-diphenyl-2-picrylhydrazyl (DPPH) hydrogen peroxide (H2O2)....
Biologically compatible vascular grafts are urgently required. The scaffoldless multi-layered wall is considered to offer theoretical advantages, such as facilitating cells form cell-cell and cell-matrix junctions natural extracellular matrix networks. Simple methods desired for fabricating physiological tissue-engineered grafts. Here, we showed that periodic hydrostatic pressurization under hypoxia (HP/HYP) facilitated the fabrication of tunica media entirely from human smooth muscle cells....
The present study reports a cost-effective and eco-friendly silver nanoparticles synthesis using Microsorum punctatum frond extract as new solution in the development of therapeutic strategies against inflammation. Egg albumin denaturation model was used to ascertain anti-inflammatory potential biosynthesized nanoparticles. Plasmon resonance surface peaked at 440 nm particles interface were coated with organics. X-ray diffraction pattern showed nanocrystallite nature 20.05 39.46 size for...
Abstract The unprecedented novel coronavirus disease 2019 (COVID‐19) pandemic is a threat to global health and the economy. Since outbreak of COVID‐19, great effort has been made reposition existing drugs shorten development timelines, in addition vaccine drug discovery campaigns. Umifenovir broad‐spectrum antiviral agent used treat influenza China Russia currently undergoing clinical trials for treatment COVID‐19. In this article, synthesis umifenovir analogues their biological evaluation...
The increasing demand to produce secure and cost-effective healthcare nanodevices is at the forefront of research in nanotechnology.The present work reports a simple eco-friendly synthetic method for silver nanoparticles using bark aqueous extract Mangifera indica (MI-AgNPs) management inflammation.MI-AgNPs were obtained following incubation mixture plant with nitrate solution (10:50 v/v).The sample was biophysically characterized Ultraviolet Visible spectroscopy (UV-Vis), Fourier Transform...
In this work, AgCl nanoparticles were synthesized from Microsorum scolopendria (MS) aqueous extract and AgNO3 solution. Preliminary confirmation was a color change light brown to dark-colored solution UV-Vis spectra surface plasmon resonance peak at 427 nm. Measured vibrational frequencies 1713 cm−1 1030 for C-O stretching of carboxylic acid or aliphatic ketone, 1547 possibly N-O nitro compounds by Infrared (FTIR) analysis explain the possible biomaterial electronegative species functional...
ABSTRACT This study examined the synthesis of silver nanoparticles (SNPs) with aqueous extracts Cyclosorus dentatus and Nephrolepis biserrata fronds evaluation their biological activities. Mixing AgNO 3 solution resulted in color change, indicating formation SNPs. UV‐Vis spectroscopy analysis gave a surface plasmon resonance (SPR) peak at approximately 420 nm, confirming presence synthesized Infrared showed C‐O, N‐O, C‐C vibrations or stretching aliphatic hydrocarbon chains x‐Ray diffraction...
Abstract Introduction Zinc oxide nanoparticles (ZnONPs) have been synthesized using a wide range of techniques, including green chemistry, because their versatility, cost effectiveness, and environmentally friendly nature, offering thereby interesting inexpensive therapeutic options. This study aimed to develop zinc as an anti-inflammatory agent Aframomum citratum seed extract. Methodology ZnONPs were prepared by the reaction between nitrate alkalineaqueous extract A. seeds. The isolated...
Abstract Verbascoside (VB), a phenylpropanoid glycoside found in many medicinal plants, is attracting the attention of researchers due to its significant clinical value. This study, for first time, attempted green synthesis silver nanoparticles (AgNPs) using VB as reducing and capping agent. The synthesized VB–AgNPs were characterized ultraviolet–visible, dynamic light-scattering, Fourier-transform infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray analyses....
Ligamentum flavum (LF) pathologies often lead to severe myelopathy or radiculopathy characterized by reduced elasticity, obvious thickening, worsened ossification. Elastin endows critical mechanical properties tissues and organs such as vertebrae ligaments. Desmosine (DES) isodesmosine (IDES) are crosslinkers of elastin monomers called tropoelastin. These potential biomarkers chronic obstructive pulmonary disease. As a biological diagnostic tool that supplements existing symptomatic,...
