A new study published in the Journal of Cannabis Research and indexed by the U.S. National Library of Medicine has found that silver and gold nanoparticles synthesized using cannabis waste extract have strong antibacterial effects against Pseudomonas aeruginosa, a drug-resistant bacteria commonly linked to hospital infections.

The research was conducted by scientists at the University of Chemistry and Technology in Czechia. Using a green synthesis method, they transformed marijuana plant waste into metal nanoparticles. These nanoparticles were then tested for their antimicrobial activity against Pseudomonas aeruginosa strains.
The nanoparticles were characterized using a series of advanced techniques, including transmission electron microscopy and X-ray diffraction. The researchers found that the silver nanoparticles in particular demonstrated strong antibacterial properties, effectively inhibiting bacterial growth and biofilm formation at low concentrations.
“This study successfully demonstrated the synthesis of silver and gold nanoparticles using Cannabis sativa waste extract and highlighted their potent antimicrobial properties”, concludes the study’s researchers. “It underscores the potential of utilizing plant waste extracts in sustainable nanomaterial synthesis and contributes to the fields of green nanotechnology and waste valorization within the circular economy. The findings also offer valuable insights into developing natural waste source-based antimicrobial agents.”
