Molecular beacon-functionalized gold nanoparticles as probes in dry-reagent strip biosensor for DNA analysis.
The highly specific molecule recognition properties of molecular beacons (MB) are combined with the unique optical properties of gold nanoparticles (Au-NPs) for the development of a dry-reagent strip-type nucleic acid biosensor (DSNAB) that enables sensitive and low-cost detection of nucleic acid samples within 15 min.
متن کاملMicrofluidic means of achieving attomolar detection limits with molecular beacon probes.
We used inline, micro-evaporators to concentrate and transport DNA targets to a nanoliter single molecule fluorescence detection chamber for subsequent molecular beacon probe hybridization and analysis. This use of solvent removal as a unique means of target transport in a microanalytical platform led to a greater than 5000-fold concentration enhancement and detection limits that pushed below t...
متن کاملMolecular beacon probes combined with amplification by NASBA enable homogeneous, real-time detection of RNA.
Molecular beacon probes can be employed in a NASBA amplicon detection system to generate a specific fluorescent signal concomitantly with amplification. A molecular beacon, designed to hybridize within the target sequence, was introduced into NASBA reactions that amplify the genomic RNA of potato leafroll virus (PLRV). During amplification, the probe anneals to the antisense RNA amplicon genera...
متن کاملmolecular beacon probes-base multiplex nasba real-time for detection of hiv-1 and hcv.
developed in 1991, nucleic acid sequence-based amplification (nasba) has been introduced as a rapid molecular diagnostic technique, where it has been shown to give quicker results than pcr, and it can also be more sensitive. this paper describes the development of a molecular beacon-based multiplex nasba assay for simultaneous detection of hiv-1 and hcv in plasma samples.a well-conserved region...
متن کاملSuper-resolution imaging of a 2.5 kb non-repetitive DNA in situ in the nuclear genome using molecular beacon probes
High-resolution visualization of short non-repetitive DNA in situ in the nuclear genome is essential for studying looping interactions and chromatin organization in single cells. Recent advances in fluorescence in situ hybridization (FISH) using Oligopaint probes have enabled super-resolution imaging of genomic domains with a resolution limit of 4.9 kb. To target shorter elements, we developed ...
