A self-enhanced renewable electrochemiluminescence biosensing platform for ultrasensitive detection of sialic acid

Herein, a boronate-affinity renewable electrochemiluminescence (ECL) biosensor was constructed based on a highly efficient Ru (II)-based composite for the sensitive detection of sialic acid (SA). Specifically, the Bi nanobelts (Bi NBs) was first used as coreactant to prepare a self-enhanced Ru(bpy)32+-Bi NBs composite, producing a strong ECL signal by shortening electronic transmission distance and reducing the energy loss.
