Rosa Canina Aqueous Extract: Chemical Characterization and Green Synthesis of Silver and Copper Nanoparticles

The term “nanoparticles” (example: silver, copper) suggests a “Nano” particle with a size range of 1–100 nm. These particles can be categorized into many classes according to their characteristics, sizes, or shapes. Metal nanoparticles can be synthesized using a variety of techniques, including chemical, electrochemical, and radiation approaches. Nevertheless, chemical processes frequently yield hazardous compounds that could have unfavorable side effects in medicinal applications. Since green chemistry can reduce or eliminate the usage of dangerous materials, it is thought to be a superior option. Due to their affordability and environmental friendliness, aqueous extracts of medicinal plants are currently being used to synthesize nanomaterials. In the current work, we synthesized silver and copper nanoparticles from the seeds of the Moroccan medicinal plant Rosa canina, and we measured their antioxidant and antibacterial properties against three strains of bacteria at varying concentrations. Based on TEM, zeta sizer, UV, and FTIR studies, the resulting nanoparticles are spherical in shape and a 50 nm of size. The larger concentration of silver nanoparticles (10 mM) demonstrated a noteworthy antibacterial action, according to the results. Indeed, a potent antimicrobial effect was reported against Staphylococcus aureus and Escherichia coli. After copper nanoparticles, the activity of the silver nanoparticles was on par with or greater than that of the conventional antibiotics. These results suggest that silver nanoparticles synthesis using Rosa canina aqueous extract can be used as an effective growth inhibitor of various microorganisms, making them applicable to diverse medical devices and antimicrobial control systems.
