In this paper, a novel electrochemiluminescence (ECL) sensor for lysophosphatidic acid (LPA) detection was developed. LPA consists of a phosphate "head" group, a "linker" region illustrated by glycerol, and a fatty acyl chain as a lipophilic "tail". The water-soluble quaternary CuInZnS quantum dots (QDs) were modified with agmatine (AGM) molecules as an ECL luminophore. On the one hand, the guanidine groups on the QDs can capture the hydrophilic head of LPA with high selectivity. On the other…

Variable Doping Induces Mechanism Swapping in Electrogenerated Chemiluminescence of Ru(bpy)32+ Core-Shell Silica Nanoparticles.

The results show that the ECL intensity of a nanosized system cannot be merely incremented acting on doping, since other parameters come into play, and think that these results could serve as valuable indications to design more efficient ECL nano- and microsized labels for ultrasensitive bioanalysis.
