The synthesis of nanoparticles by green chemistry offers a method that respects the environment. The experimental conditions and the existing interactions between the reducing agents in Cupressus goveniana extract and the Au +3 ions have a directly influence in the size, morphology and stability, as well as the physicochemical properties of the particles. Is possible consider he formation of AuNPs in the change of color of the extract when adding the precursor agent and by UV-Visible spectroscopy, indicating a plasmon of absorbance characteristic of this metal. The extract was characterized by FTIR, and to evaluate the reductive capacity of Cupressus goveniana extract, a cyclic voltammetry was carried out, for which the reducing capacity of the Au +3 ions is attributed to obtain the AuNPs.

Green synthesis as an alternative technique for bioproduction of metallic nanomaterials has presented a great interest due to the composition of reducing agents in plants, bacteria, and fungi that favor the production of nanostructured materials. In this investigation, the extract of Thuja Orientalis was used to evaluate the synthesis of copper nanoparticles. The species presents biomolecules which make it a candidate for the reduction of metal ions. The FTIR analysis showed the presence of functional groups OH, CH, C=O, COOH, -OCH3, C-O-C proper to polyphenols, terpenes, and ligands. The kinetics of CuNPs synthesis was analyzed by UV-vis in which a narrow absorbance band was shown at 400 nm after 20 minutes of reaction using a concentration of precursor agent of 50 mM, giving us indications of a homogeneous system of nanoparticles, which was corroborated by SEM obtaining a particle size between 5-60 nm with a spherical morphology. By cyclic voltammetry, the reducing power of the extract against the ions of Cu+2 to Cu0 was demonstrated, as well as its tendency to oxidation, which can have great advantages in different applications.

Background Nanotechnology's rapid development has been in great demand, particularly for silver nanoparticles, which are useful in a variety of industries including medicine, textiles, and home appliances. Silver nanoparticles are extremely essential due to their unique physicochemical and antibacterial properties, which can be used in a variety of applications. Green synthesis is an environmentally friendly alternative to conventional synthesis because it uses fewer chemical reagents and lowers temperature and pressure. Aloe vera and Thuja orientalis have a wide medical use because it contains a large number of compounds derived and was decided to use for the synthesis of nanoparticles. Main text The combination of silver nanoparticles has a wide range of applications, which has encouraged researchers to focus on the methods for the synthesis of silver nanoparticles from Aloe vera and Thuja orientalis leaves extract, characterization techniques of synthesized silver nanoparticles, and evaluation of their antimicrobial and antifungal activities. The synthesized AgNPs can be characterized by using various analytical techniques including UV–visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), etc. The various types of silver nanoparticles, various strategies for silver nanoparticle synthesis, nano-based drug delivery systems, taxonomy and chemical constituents of Aloe vera and Thuja orientalis plants, the general mechanism of action of silver nanoparticles in bacteria, and various applications of silver nanoparticles have also been discussed. Conclusion This review covers a wide range of research on silver nanoparticles to gain a better understanding of their physicochemical feature characterization, production, mechanisms of action, and applications. Various AgNP factors, such as size, surfactant, and structural shape, influence the unique physicochemical properties of these nanoparticles. Even though there are a variety of ways to make AgNPs, green synthesis has a high yield and biocompatibility because it uses natural agents and harmless chemicals. In this paper, we describe the green manufacture of silver nanoparticles utilizing Aloe vera and Thuja orientalis leaf extracts, as well as the method to test their antimicrobial and antifungal activity.
