She added, “The use of Cannabis sativa and Vitis vinifera waste not only addresses waste management challenges but also provides an effective method to combat microbial infections.”
The research focused on extracting bioactive compounds from plant scrap materials, which were subsequently combined with silver nitrate and tetrachloroauric acid to synthesize bimetallic nanoparticles (AgAuNPs).
The nanoparticles were analyzed using a range of advanced techniques, including UV-Vis spectrophotometry, transmission electron microscopy, and X-ray diffraction. The study found that these nanoparticles demonstrated notable antimicrobial properties against several strains of Pseudomonas aeruginosa, a well-known Gram-negative bacterium.
“The antimicrobial properties of the biosynthesized AgAuNPs are particularly promising. They not only inhibit the growth of Pseudomonas aeruginosa but also prevent biofilm formation, which is crucial in the fight against antibiotic-resistant infections,” Michailidu added.
The study highlights the dual advantages of this method: it not only addresses waste management effectively but also yields valuable antimicrobial agents.
Michailidu concluded, “This research supports the development of eco-friendly and cost-effective approaches for nanoparticle production, addressing both environmental and public health challenges.”
The successful synthesis and characterization of these nanoparticles represent a significant advancement in sustainable nanotechnology. The University of Chemistry and Technology in Prague remains at the forefront of pioneering research that supports global sustainability objectives.
