Rapid genotyping using pyrene−perylene locked nucleic acid complexes

Locked nucleic acid molecular beacons.

A novel LNA-MB (molecular beacon based on locked nucleic acid bases) has been designed and investigated. It exhibits very high melting temperature and is thermally stable, shows superior single base mismatch discrimination capability, and is stable against digestion by nuclease and has no binding with single-stranded DNA binding proteins. The LNA-MB will be widely useful in a variety of areas, ...

Locked nucleic acids: promising nucleic acid analogs for therapeutic applications.

Locked Nucleic Acid (LNA) is a unique nucleic-acid modification possessing very high binding affinity and excellent specificity toward complementary RNA or DNA oligonucleotides. The remarkable properties exhibited by LNA oligonucleotides have been employed in different nucleic acid-based therapeutic strategies both in vitro and in vivo. Herein, we highlight the applications of LNA nucleotides f...

Single nucleotide polymorphism genotyping using short, fluorescently labeled locked nucleic acid (LNA) probes and fluorescence polarization detection.

Locked nucleic acids (LNAs) are synthetic nucleic acid analogs that bind to complementary target molecules (DNA, RNA or LNA) with very high affinity. At the same time, this binding affinity is decreased substantially when the hybrids thus formed contain even a single mismatched base pair. We have exploited these properties of LNA probes to develop a new method for single nucleotide polymorphism...

Mapping Photothermally Induced Gene Expression in Living Cells and Tissues by Nanorod-Locked Nucleic Acid Complexes

The photothermal effect of plasmonic nanostructures has numerous applications, such as cancer therapy, photonic gene circuit, large cargo delivery, and nanostructure-enhanced laser tweezers. The photothermal operation can also induce unwanted physical and biochemical effects, which potentially alter the cell behaviors. However, there is a lack of techniques for characterizing the dynamic cell r...
