Eco-friendly silver nanoparticles from neem extracts: a dual approach to heavy metal sensing and antimicrobial applications

Key Points

• Silver nanoparticles synthesized using neem extracts demonstrate effective heavy metal sensing capabilities, reducing environmental impact.
• Heavy metal detection using these nanoparticles showed a notable sensitivity, achieving detection limits less than 10 ppb in solution.
• Assessment involved eco-friendly extraction techniques, combining antimicrobial activity tests against common bacterial strains.
• This work supports the potential for green synthesis of silver nanoparticles as a sustainable alternative for healthcare and environmental monitoring.
