Abstract
In this research, we obtained nanoparticles (NPs) using a type of microwave (cold plasma) and water extract from Origanum vulgare with the addition of silver nitrate (AgNO3) solution. Silver nanoparticles are characterized by high production techniques. Experimental factors such as morphology, structure, optical properties and active compounds of the nanoparticle extract were studied through specific tests such as morphology, UV spectroscopy, FE-SEM, FT-IR, and Atomic Force Microscopy (AFM). Plants were used in manufacturing the nanoparticles, as plants are well known for their accessibility and applicability in different pathological areas. The current research provides information on the Green Union System of Nanoparticles. It is concluded that, under the influence of cold plasma, the nanoparticles increased the nanoscale size of the molecules and thus increased the aggregation and the transformation of the pink color of the nanocrystal line to brown due to increased absorption.
Highlights
Nanomaterials are defined as materials of external dimensions and / or internal structures within the nanometer scale
Various studies showed that O. vulgare has many medicinal and therapeutic properties
The active compounds of O. vulgare were studied, and the results showed that the active compounds contained in the herb after being converted into a water extract include flavonoids, phenols, resins, essential oils, saponins, terpenoides and tannins [13]
Summary
Nanomaterials are defined as materials of external dimensions and / or internal structures within the nanometer scale (nm). The 100 nm scale is adopted by many organizations/countries to distinguish between large nanoparticles and macromolecules [1]. This field is known as nanotechnology, which allows us to produce nano-scale apparatus. The exact size of the nano system in all these organizations/states is about 100 nm These materials are of different dimensions and shapes, including 0D, 1D, 2D or 3D, depending on the general shape. The chemical method identifies three major factors for the synthesis of green synthesis, including the use of a non-toxic fixing agent, the choice of solvent intermediary and the use of a natural reduction factor, while the green methods are classified as a biological method [7.]
