Abstract

Aside from salmon DNA, other DNA sources were explored namely, herring and onion, to prepare DNAsurfactant complex, which will be used as a template for dyes undergoing Forster Resonance Energy Transfer (FRET). Also, salmon DNA of low and high molecular weight were compared. This study aims to assess the effect of using different DNA sources and molecular weight on the efficiency of energy transfer between the dyes, coumarin 480 (Cm 480) and 4-[4-(dimethylamino)styryl]-1-docosyl-pyridinium bromide (Hemi 22 and to understand the fundamental properties of DNA-CTMA as a supporting matrix for optoelectronics applications.
