An ultrasensitive electrochemiluminescent <scp>d</scp>-alanine biosensor based on the synergetic catalysis of a hemin-functionalized composite and gold–platinum nanowires

Abstract

Herein, an ultrasensitive and stereo-selective electrochemiluminescent (ECL) biosensor based on ECL signal amplification of luminol by the synergetic catalysis of a hemin-functionalized composite and gold–platinum nanowires (Au-PtNWs) has been designed for the detection of <sc>d</sc>-alanine (<sc>d</sc>-Ala).
