Heavy metal ion contamination is a significant, invisible threat to public health. Government agencies actively survey and maintain established regulatory limits on heavy metal contamination, but prioritized to localized hotspots in high-risk communities. The characterization techniques of heavy metal ions are typically expensive, time consuming, and requiring specialized training. In this work, a bismuth nanoflower structure has been developed as a potential nontoxic sensor material for detection of heavy metal ions. The high surface area nanostructure was synthesized via aqueous chemical reduction of bismuth chloride salt in a micellar environment, designed for high sensitivity by consideration of the crystallization mechanism in optimization of associated parameters. The nanoflower structure was deposited onto an electrode and coated with a Nafion layer, achieving a lower detection limit for lead and zinc, respectively. These results indicate the viability of bismuth-based nanoflower structures for portable, accessible detection of heavy metal ions, with enhanced sensitivity.
