title: Autocatalytic amplified detection of DNA based on a CdSe quantum dot/folic acid electrochemiluminescence energy transfer system.
abstract: In this work, electrochemiluminescence energy transfer (ECL-ET) from CdSe quantum dots (QDs) to folic acid is reported for the first time and applied for amplified detection of DNA by using a novel DNAzyme-mediated autocatalytic system.
