摘要:
DNA hairpin-based fluorescent probes (DHFPs) are widely used in molecular biology, biosensor development, mRNA monitoring in living cells and imaging in vivo. In this review, we focus on the typical designs and the recent bioanalytical applications of DHEPs. We describe the application of different materials with excellent photophysical properties as signal labels to reduce the background and to increase the brightness of the DHFPs. These labels range from dye molecules to nanomaterials. We also discuss the general design of signal-transduction mechanisms. (C) 2013 Elsevier Ltd. All rights reserved.
