The authors describe a voltammetric sensor for trace analysis of streptomycin (STR). It is based on the use of a glassy carbon electrode that was modified with a film of STR-imprinted poly(pyrrole-3-carboxy acid) (PPy3C) on electrochemically reduced graphene oxide (ERGO). ERGO was first deposited on the surface of GCE by electro-reduction, this followed by deposition of a film of STR-imprinted PPy3C...
