General description

Proflavine is a small, amphipathic, acridine-derived fluorescent dye.Proflavine hemisulfate is used as a rapid stain for cytological studies of biological specimens. It stains cytoplasmic structures and nuclei. Proflavine has the capability to intercalate double stranded DNA.

Application

Proflavine hemisulfate salt hydrate has been used to stain cells of the 1483 cell line. It has also been used as a calibrating dye in fluorescence resonance energy transfer (FRET) analysis.

The transfer of photoenergized electrons from extracellular photosensitizers across a bacterial cell envelope to drive intracellular chemical transformations represents an attractive way to harness nature's catalytic machinery for solar-assisted chemical synthesis. In Shewanella oneidensis MR-1 (MR-1), trans-outer-membrane electron transfer is

Optical fiber bundle microendoscopes are widely used for visualizing hard-to-reach areas of the human body. These ultrathin devices often forgo tunable focusing optics because of size constraints and are therefore limited to two-dimensional (2D) imaging modalities. Ideally, microendoscopes would record
