![]() ![]() Naturally, we were tempted to verify the wisdom of the local community in using these plants as herbal drugs. It has been usually used for the treatment of puerperal diseases, as digestive tonics and in the treatment of ulcers, fevers, wounds, other ailments and general debility. It is found in different parts of the world such as tropical Africa, Sri Lanka, India, Mexico and Pakistan (Rajashekar et al. murex) is a member of the sesame family, Pedaliaceae. 2012), Cycas circinalis, Ficus amplissima, Commelina benghalensis, Lippia nodiflora (Johnson and Prabu 2015), Ocimum sanctum (Garima Singhal et al. 2013), Iresine herbstii (Dipankar and Murugan 2012), Tribulus terrestris (Gopinath et al. 2013), Morinda citrifolia (Sathishkumar et al. Many biological approaches of green synthesis have been reported till date using plant leaf extracts from Alternanthera sessilis (Niraimathi et al. Ag nanoparticles have been synthesised by different physical and chemical approaches viz., chemical reduction, microemulsion/reverse micelles, electrochemical reduction and photochemical reduction. In the medical field, silver and silver nanoparticles have broad applications, especially in skin ointments and creams to avoid infection of burns and open wounds (Duran et al. The green synthesis method utilizes nontoxic chemicals, eco-friendly solvent and renewable materials (Raveendran et al. The general method of synthesizing silver nanoparticles in chemical reduction is as colloidal dispersions in water or organic solvents (Sharma et al. Silver is well known for possessing an inhibitory result toward many bacterial strains and microorganisms commonly present in medical and industrial processes (Jiang et al. They are ahead of time the interest of researchers for their novel method for synthesis of silver nanoparticles. The silver nanoparticles have a large area of interest as they have a large number of applications: nonlinear optics, spectrally selective coating for solar energy absorption, biolabeling, intercalation materials for electrical batteries as optical receptors, catalyst in chemical reactions, antibacterial materials, chemically stable materials and good electrical conductors (Zargar et al. Metal nanoparticles, particularly noble metals, have been studied mainly because of their strong optical absorption in the visible region caused by the group excitation of the free electron gas (Mohamed et al. Synthesis of metal nanoparticles is enormous due to their potential applicability in different areas such as electronics, chemistry, energy, and medicine development (Saxena et al. Metal nanoparticles have a high specific surface area and surface atoms, because of their outstanding physicochemical characteristics, including optical, catalytic, electronic, magnetic and antibacterial properties. Noble metal nanoparticles have been gaining a lot of significance in the past few years due to their applicability in the field of physics, chemistry, medicine, biology and material science (Yokohama and Welchons 2007). One of the important aspects in the field of nanotechnology is the development of a more consistent process for the synthesis of nanomaterials more than a range of size (with good monodispersity) and chemical composition (Rai et al. Nano-biotechnology has emerged as an important division of nanotechnology. The antibacterial activity of AgNPs against generally found bacteria was assessed to find their potential use in silver-containing antibacterial product. The size and stability were detected using DLS and zeta potential analysis. XRD study showed the particles to be crystalline in nature, with a face-centered cubic (fcc) structure. Fourier transform infrared spectra had shown that the biomolecule compounds were responsible for the reduction and capping material of silver nanoparticles. UV–visible spectrum of the aqueous medium containing silver nanoparticles showed absorption peak at around 430 nm. Characterization of nanoparticles was done using different methods, which include ultraviolet–visible spectroscopy (UV–Vis), Fourier transform infrared (FTIR), powder X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), energy dispersive X-ray analysis (EDAX), fluorescence emission spectroscopy, transmission electron microscope (TEM), dynamic light scattering (DLS), zeta potential and antibacterial activity. The use of plants in the green synthesis of nanoparticles emerges as a cost-effective and eco-friendly approach. Different biological methods are gaining recognition for the production of silver nanoparticles (AgNPs) due to their multiple applications. In this paper, an aqueous extract of fresh leaves of Pedalium murex was used for the synthesis of silver (Ag) nanoparticles. ![]()
