This is the authors' abstract. We don't add key points for this paper.

The process of producing metal nanoparticles via plant extract synthesis is not only straightforward but also economical, expeditious, and environmentally sustainable. It is consequently implemented in an extensive range of disciplines. In the process of producing silver nanoparticles (AgNPs), an extensive variety of plant extracts was employed. The production of silver nanoparticles was conducted using an environmentally sustainable method in this investigation. A reducing and stabilizing agent was derived from the aqueous extract of the Aloe vacillans Forsskål plant. In order to ascertain the ideal conditions for silver nanoparticle synthesis, an examination of the effects of a number of process parameters was required. The reactant volume ratio, pH values, and temperature were among these parameters. An aqueous solution of AgNO 3 was incorporated into an aqueous extract of the A. vacillans plant under optimal conditions to obtain crystalline and stable silver nanoparticles. The green‐produced AgNPs were investigated and characterized through the utilization of a variety of techniques (UV‐Vis spectrophotometer, FTIR, XRD, SEM, EDX, and XPS). It was demonstrated by means of the SEM technique that AgNPs possess a tetrahedral morphology. The X‐ray diffraction analysis identified the dimensions of crystalline AgNPs as 19.59 nm. Antibacterial properties of optimally synthesized AgNPs are significant and efficacious against a wide range of bacterial species, as determined by dosing experiments. In this work, the antioxidant activity studies for these synthesized AgNPs revealed a moderate effect for the DPPH free radicals at various concentrations.
