An　amplified　and　stable　electrochemiluminescent　signal　of　lucigenin　was　observed　on　an　electrochemically　reduced　graphene　oxide-containing　sensing　platform.　Herein,　chitosan　was　used　as　an　excellent　dispersant,　which　favors　the　better　dispersion　of　graphene　oxide　in　solution　and　improved　electrochemical　reduction　of　graphene　oxide.　The　electrochemically　reduced　graphene　oxide　showed　outstanding　conductivity　which　was　propitious　to　the　transfer　of　electrons,　leading　to　the　enhancement　of　the　electrochemiluminescent　signals　of　lucigenin.　In　addition,　bisphenol　A,　as　a　classical　food　borne　pollutant,　was　first　detected　due　to　its　strong　inhibiting　action　of　the　electrochemiluminescent　response　of　lucigenin.　Then,　we　studied　the　quenched　electrochemiluminescent　system　and　the　possible　mechanism　of　the　platform　in　detail.　Under　optimum　conditions,　the　proposed　electrochemiluminescent　sensor　exhibited　a　linear　response　range　from　1.0　×　10-9　mol　L-1　to　1.0　×　10-4　mol　L-1　with　a　low　detection　limit　of　3.0　×　10-10　mol　L-1　for　bisphenol　A,　which　might　find　promising　applications　in　developing　a　new　type　of　biosensor.　©　the　Partner　Organisations　2014.
