FRET is a nonradiative process of energy transfer that is based on the dipole–dipole
interactions between molecules that are fluorescent. Transfer of energy takes place rapidly …

The chemical composition of cells at the molecular level determines their growth,
differentiation, structure, and function. Probing this composition is powerful because it …

Seeing is not only believing; it also includes understanding. Cellular imaging with GFP in
live cells has been transformative in many research fields. Modulation of cellular regulation …

RNA plays an important role in life processes. Imaging of messenger RNAs (mRNAs) and
micro-RNAs (miRNAs) not only allows us to learn the formation and transcription of mRNAs …

An RNA-based fluorogenic module consists of a light-up RNA aptamer able to specifically
interact with a fluorogen to form a fluorescent complex. Over the past decade, significant …

A whole-cell biosensor based on synthetic biology provides a promising new method for the
on-site detection of food contaminants. The basic components of whole-cell biosensors …

Functional nucleic acids with fluorescence properties are powerful research tools for both
biomolecular analysis and biological nanomaterials. This review collected these interesting …

An RNA aptamer selected for binding to the fluorogenic cyanine dye, dimethylindole red
(DIR), also binds and activates another cyanine, oxazole thiazole blue (OTB), giving two well …

Ochratoxin A (OTA) is a mycotoxin identified as a contaminant in grains and wine throughout
the world, and convenient, rapid and sensitive detection methods for OTA have been a long …

The organization of molecules into cells is believed to have been critical for the emergence
of living systems. Early protocells likely consisted of RNA functioning inside vesicles made of …
