Abstract
Novel functional oligonucleotides, especially DNAzymes with RNA-cleavage activity,have been intensively studied due to their potential applications in therapeuticsand sensors. Taking advantage of the high specificity of 17E DNAzyme forPb2+,highly sensitive and selective fluorescent, electrochemical and colorimetric sensors have been developedfor Pb2+. In this work, we report a simple, sensitive and label-free 17E DNAzyme-based sensor forPb2+ detection using unmodified gold nanoparticles (GNPs) based on the fact that unfoldedsingle-stranded DNA could be adsorbed on the citrate protected GNPs while double-strandedDNA could not. By our method the substrate cleavage by the 17E DNAzyme in the presence ofPb2+ could be monitored by color change of GNPs, therebyPb2+ detection was realized.The detection of Pb2+ could be realized within 20 min, with a detection limit of 500 nM. The selectivity of our sensorhas been investigated by challenging the sensing system with other divalent metal ions. Sincecommon steps such as modification and separation could be successfully avoided, the sensordeveloped here could provide a simple, cost-effective yet rapid and sensitive measurement tool forPb2+ detection and may prove useful in the development of sensors for clinical toxicology andenvironmental monitoring in the future.
