Dual Signal Amplification Based on TiO2 Nanotube Layers and CdTe Quantum Dots for Electrochemiluminescent Immunosensing

Herein, a novel strategy for the construction of a photoelectrochemical aptasensor for tumor marker mucin 1 (MUC1) was presented, which was based on the effective photoelectron transfer from CdTe quantum dots (QDs) to TiO2 nanotube arrays (TiO2 NTs) through DNA chains.
