Abstract:
Combining with the synergic effect of carbon nanotubes and ionic liquids for enhancing electrochemiluminescence (ECL) response of CdSe QDs, a universal strategy for highly sensitive biosensing was designed. Using alpha-fetoprotein as a model and monitoring the variation of ECL intensity before and after immunoreaction, a label-free ECL biosensor was developed.
