چکیده
A catalytic beacon sensor for Pb(2+) has been developed based on the first DNAzyme discovered in the field, and such a sensor has shown a much higher metal ion selectivity (40,000 times) than the previously reported Pb(2+) sensor based on 8-17 DNAzyme and thus is suitable for a wider range of practical applications.

A highly selective lead sensor based on a classic lead DNAzymew
Wide-spread Pb contamination has posed adverse effects on human health, especially on children. To reverse the negative effects, accurate, on-site and real-time detection and quantification of Pb in the environment or in vivo is an important first step. Toward this goal, a number of Pb sensors have been developed. Among them, DNAzymes have emerged recently as a promising class of molecules to b...
متن کاملAn Electrochemical Sensor Based on Novel Ion Imprinted Polymeric Nanoparticles for Selective Detection of Lead Ions
In this study, the novel surface ion-imprinted polymer (IIP) particles were prepared and applied as a electrode modifier in stripping voltammetric detection of lead(II) ion. A carbon paste electrode (CPE) modified with IIP nanoparticles and multi-walled carbon nanotubes (MWCNTs) was used for accumulation of toxic lead ions. Various factors that govern on electrochemical signals including carbon...
متن کاملA portable DNAzyme-based optical biosensor for highly sensitive and selective detection of lead (II) in water sample.
A portable, rapid and cost-effective DNAzyme based sensor for lead ions detection in water samples has been developed using an optical fiber sensor platform. The presence of Pb(2+) cleaves the DNAzymes and releases the fluorescent labeled fragments, which further hybridize with the complementary strands immobilized on the optic fiber sensor surface. Subsequent fluorescent signals of the hybridi...
متن کاملMiniaturized lead sensor based on lead-specific DNAzyme in a nanocapillary interconnected microfluidic device.
A miniaturized lead sensor has been developed by combining a lead-specific DNAzyme with a microfabricated device containing a network of microfluidic channels that are fluidically coupled via a nanocapillary array interconnect. A DNAzyme construct, selective for cleavage in the presence of Pb2+ and derivatized with fluorophore (quencher) at the 5' (3') end of the substrate and enzyme strands, r...
متن کاملA colorimetric lead biosensor using DNAzyme-directed assembly of gold nanoparticles.
A highly sensitive and selective colorimetric lead biosensor based on DNAzyme-directed assembly of gold nanoparticles is reported. It consists of a DNAzyme and its substrate that can hybridize to a 5'-thio-modified DNA attached to gold nanoparticles. The hybridization brings gold nanoparticles together, resulting in a blue-colored nanoparticle assembly. In the presence of lead, the DNAzyme cata...
