Selective adsorption toward toxic metal ions results in selective response: electrochemical studies on a polypyrrole/reduced graphene oxide nanocomposite.

Highly selective adsorption of a polypyrrole/reduced graphene oxide nanocomposite toward Hg(2+) results in electrochemically selective detection of Hg(2+). This interesting finding is of practical utility compared to the biotechniques and surface functionalization-based methods. This journal is © The Royal Society of Chemistry 2012
