A　promising　electrochemiluminescence　(ECL)　sensing　strategy　was　proposed　with　dual-stabilizers-capped　CdSe　quantum　dots　(QDs)　as　ECL　emitters.　The　dual-stabilizers-capped　CdSe　QDs　were　covalently　immobilized　onto　p-aminobenzoic　acid　modified　glass　carbon　electrode　with　ethylenediamine　as　a　link　molecule.　This　strategy　can　preserve　the　completely　passivated　surface　states　of　dual-stabilizers-capped　CdSe　QDs,　so　that　the　sensor　demonstrated　eye-visible　greenish,　band　gap　engineering　and　monochromatic　ECL　emission　at　546　nm　with　a　fwhm　of　35　nm.　Moreover,　the　proposed　sensor　could　accurately　quantify　dopamine　from　10.0　nM　to　3.0　mu　M　with　a　detection　limit　of　3.0　nM　in　practical　drug,　human　urine,　and　cerebrospinal　fluid　samples　without　any　signal　amplification　techniques.　This　strategy　is　promising　for　developing　ECL　sensors　with　high　sensitivity　and　spectral　selectivity.
