Overview

Novel approach develops an electrochemical sensor for Pb(II) and Hg(II), suggesting improvements in detection sensitivity through pattern pitch modification.

Key Points

  • The research introduces an innovative electrochemical sensor utilizing dip-pen nanolithography.
  • Sensitivity, measured by LoD, shows 0.84 ppb and 0.99 ppb for Pb(II) and Hg(II), respectively.
  • The findings reveal that pattern pitch significantly impacts the sensor's fill factor and sensitivity.
  • Altering the pattern pitch offers potential advancements in heavy metal sensing technology.
