Quencher-Free Fluorescence Method for the Detection of Mercury(II) Based on Polymerase-Aided Photoinduced Electron Transfer Strategy [PDF]
Sensors, 2016 A new quencher-free Hg2+ ion assay method was developed based on polymerase-assisted photoinduced electron transfer (PIET). In this approach, a probe is designed with a mercury ion recognition sequence (MRS) that is composed of two T-rich functional ...

Cocoa fresh beans aqueous extract as free radical quencher and ferric reducer.
Coffee and Cocoa Research Journal, 2022 The presence of free radicals and oxidants in our body is either produced by our body through normal cell metabolisms or from environment surrounding us such as radiation, medication, pollutants or others. The free radicals and oxidants can be harmful to

Synthesis and Photostability of Cyclooctatetraene-Substituted Free Base Porphyrins
Chemistry, 2021 A series of free base meso-tetraarylporphyrins functionalized with substituents containing one, two, and four cyclooctatetraene (COT) moieties have been obtained and characterized by spectral and photophysical studies. Three COT-free porphyrins served as

Photounbinding of calmodulin from a family of CaM binding peptides. [PDF]
PLoS ONE, 2010 Recent studies have shown that fluorescently labeled antibodies can be dissociated from their antigen by illumination with laser light. The mechanism responsible for the photounbinding effect, however, remains elusive.
