An ultrasensitive DNAzyme-based colorimetric strategy for nucleic acid detection.
نویسندگان
چکیده
An ultrasensitive DNAzyme-based colorimetric DNA detection strategy was developed by utilizing gold nanoparticles modified with both peroxidase-mimicking DNAzymes and capture DNAs and magnetic nanoparticles modified with another capture DNAs, with a detection limit for a model Chlamydia gene of 50 fM.

Ultrasensitive Visual Detection of HIV DNA Biomarkers via a Multi-amplification Nanoplatform
Methodologies to detect disease biomarkers at ultralow concentrations can potentially improve the standard of living. A facile and label-free multi-amplification strategy is proposed for the ultrasensitive visual detection of HIV DNA biomarkers in real physiological media. This multi-amplification strategy not only exhibits a signficantly low detection limit down to 4.8 pM but also provides a l...
متن کاملDNAzyme molecular beacon probes for target-induced signal-amplifying colorimetric detection of nucleic acids.
A novel DNAzyme molecular beacon (DNAzymeMB) strategy was developed for target-induced signal-amplifying colorimetric detection of target nucleic acids. The DNAzymeMB, which exhibits peroxidase activity in its free hairpin structure, was engineered to form a catalytically inactive hybrid through hybridization with a blocker DNA. The presence of target DNA leads to dissociation of the DNAzymeMB ...

MicroRNAs are small regulatory molecules that can be used as potential biomarkers of clinical diagnosis, and efforts have been directed towards the development of a simple, rapid, and sequence-selective analysis of microRNAs. Here, we report a simple and versatile colorimetric strategy for ultrasensitive and specific determination of microRNAs based on molecular beacon initiated strand displace...
متن کاملA colorimetric biosensor for detection of attomolar microRNA with a functional nucleic acid-based amplification machine.
A functional nucleic acid-based amplification machine was designed for simple and label-free ultrasensitive colorimetric biosensing of microRNA (miRNA). The amplification machine was composed of a complex of trigger template and C-rich DNA modified molecular beacon (MB) and G-rich DNA (GDNA) as the probe, polymerase and nicking enzyme, and a dumbbell-shaped amplification template. The presence ...
