A sensitive SERS assay of L-histidine via a DNAzyme-activated target recycling cascade amplification strategy.
نویسندگان
چکیده
A novel surface-enhanced Raman scattering (SERS) method is demonstrated to detect L-histidine based on DNAzyme which can specifically recognize L-histidine. Through a target recycling cascade amplification strategy, the DNAzyme-based SERS sensing system affords very high sensitivity for L-histidine with a detection limit of 0.56 nM.

A target-activated autocatalytic DNAzyme amplification strategy for the assay of base excision repair enzyme activity.
Based on a target-activated autocatalytic DNAzyme amplification strategy, novel fluorescence sensing platforms were constructed for highly sensitive and selective assay of base excision repair enzyme activity. By using a rolling circle amplification (RCA)-coupled amplification cascade, an extremely low detection limit (0.002 U mL(-1)) was achieved.
متن کاملA cascade signal amplification strategy for sensitive and label-free DNA detection based on Exo III-catalyzed recycling coupled with rolling circle amplification.
A sensitive and label-free fluorescence assay for DNA detection has been developed based on cascade signal amplification combining exonuclease III (Exo III)-catalyzed recycling with rolling circle amplification. In this assay, probe DNA hybridized with template DNA was coupled onto magnetic nanoparticles to prepare a magnetic bead-probe (MNB-probe)-template complex. The complex could hybridize ...
متن کاملA DNAzyme cascade for the amplified detection of Pb(2+) ions or L-histidine.
DNAzyme cascades activated by Pb(2+)- or L-histidine-dependent DNAzymes yield the horseradish peroxidase-mimicking catalytic nucleic acids that enable the colorimetric or chemiluminescence detection of Pb(2+) or L-histidine.
متن کاملA SERS DNAzyme biosensor for lead ion detection.
SERS biosensor for sensitive and selective detection of lead ions (Pb(2+)) based on DNAzyme was developed by taking advantage of the specific catalytic reaction of DNAzyme upon binding to Pb(2+) ions. Detection was accomplished by SERS nanoprobe labeled with DNA and Raman reporters for signal amplification.
متن کاملA sensitive quartz crystal microbalance assay of adenosine triphosphate via DNAzyme-activated and aptamer-based target-triggering circular amplification.
In this work, a simple and novel quartz crystal microbalance (QCM) assay is demonstrated to selectively and sensitively detect the adenosine triphosphate (ATP). The amplification process consists of circular nucleic acid strand-displacement polymerization, aptamer recognition strategy and nanoparticle signal amplification. With the involvement of an aptamer-based complex, two amplification reac...
