Abstract

Key findings

  • The MFC biosensor showed high sensitivity and specificity in detecting heavy metal ions in wastewater.
  • The biosensor was able to detect heavy metal ions at concentrations as low as 1 ppm.
  • The MFC biosensor was reusable and self-powered, eliminating the need for external power sources.
