An ultrasensitive peroxidase DNAzyme-associated aptasensor that utilizes a target-triggered enzymatic signal amplification strategy.
نویسندگان
چکیده
By rationally employing enzymes for signal amplification, an ultrasensitive aptasensor was developed and successfully tested in a system designed to detect lysozyme with a detection limit of 0.1 fM. This detection limit is nearly three orders of magnitude lower than those of any previously reported DNAzyme-based aptasensors.

An ultrasensitive electrochemical aptasensor for thrombin based on the triplex-amplification of hemin/G-quadruplex horseradish peroxidase-mimicking DNAzyme and horseradish peroxidase decorated FeTe nanorods.
In the present study, we fabricated an ultrasensitive sandwich-type electrochemical aptasensor for thrombin (TB) based on a triplex signal amplification strategy. The hemin/G-quadruplex horseradish peroxidase-mimicking DNAzyme (HRP-DNAzyme) as well as blocking reagent-horseradish peroxidase (HRP) and iron telluride nanorods (FeTe NRs) could simultaneously amplify the electrochemical signal of t...

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 ...
متن کاملA target-triggered exponential amplification-based DNAzyme biosensor for ultrasensitive detection of folate receptors.
We develop a new method for ultrasensitive detection of folate receptors (FRs) using a target-triggered isothermally exponential amplification reaction (EXPAR)-based DNAzyme biosensor. This method exhibits excellent specificity and high sensitivity with a detection limit as low as 0.23 fM and a large dynamic range of 6 orders of magnitude from 1 fM to 1 nM. It might be further applied for the d...
