Silver nanoparticles can be produced using simple, inexpensive, and eco-friendly plant extracts. An aqueous extract of the plant Aloe fleurentinorum was employed as both a reducing and stabilising agent to manufacture silver nanoparticles. Evaluating several process parameters established that optimal synthesis occurs using a 0.01 molar silver nitrate solution at 60 degrees Celsius, a pH of 8, and a reaction time of 90 minutes. Detailed physical and chemical characterisation showed that the resulting crystalline nanoparticles have an average size of 26.7 nanometres and possess a tetrahedral morphology. When tested across different doses, the optimally produced silver nanoparticles demonstrated significant and effective antibacterial activity against several bacterial species, confirming the viability of this biological synthesis route.
Green synthesis offers a sustainable and cost-effective alternative to conventional chemical methods for producing nanomaterials. Utilizing plant extracts avoids hazardous chemicals, reducing environmental impact while yielding functional materials. The demonstrated antibacterial effectiveness against multiple bacterial strains makes this approach relevant to the development of safer antimicrobial agents and cleaner manufacturing techniques.
This research is at an early laboratory stage, demonstrating synthesis optimisation and antibacterial screening. The findings could eventually enable the development of plant-derived antimicrobial agents, surface sanitizers, or biomedical coatings. Potential users include manufacturers of hygiene products or antimicrobial formulations seeking greener precursors, though substantial formulation, stability, and safety testing remain necessary before commercial adoption.

The synthesis of metal nanoparticles through the use of plant extract is a process that is not only simple but also inexpensive, quick, and favorable to the environment. As a result, it is utilized in a wide variety of fields. When synthesizing silver nanoparticles (AgNPs), several different kinds of plant extracts were utilized. The manufacture of silver nanoparticles was carried out in this study using an environmentally friendly technique. The aqueous extract of the Aloe fleurentinorum plant was utilized as a stabilizing and reducing agent. To determine the optimal conditions for the synthesis of silver nanoparticles, it was necessary to investigate the impact of several parameters on the process. These parameters included the reactant volume ratio, pH values, temperature, and reaction time. To get crystallite and stable silver nanoparticles, an aqueous solution of AgNO 3 (0.01M) was added to an aqueous extract of Aloe fleurentinorum plant at a temperature of 60 degrees Celsius and a pH of 8. The mixture was then stirred with a magnetic stirrer for ninety minutes (90 minutes). Using a variety of methods (UV‐vis spectrophotometer, FTIR, XRD, SEM, EDX, and XPS), several approaches were utilized to investigate and describe the green‐produced AgNPs. Through the use of the SEM method, it was demonstrated that the morphology of AgNPs is tetrahedral. It was determined using X‐ray diffraction that the size of crystalline AgNPs was 26.7 nm. AgNPs that have been optimally synthesized have antibacterial properties that are both significant and effective against various bacterial species that have been tested at varying doses.
