Influence of DNA on Ag(I)-C-Phycocyanin complexes
  The effects of DNA on the fluorescence of silver phycocyanin complexes were investigated. It was shown, that the fluorescence intensity of phycocyanin decreases, when silver ions are added but the following DNA addition gives rise to fluorescence buildup. Fluorescence spectroscopy provides insight of silver phycocyanin interactions. Fluorescence measurements demostrate phycocyanin quenching of silver emission intensities. SternVolmer quenching constant was obtained from the linear quenching plot. Blue shifts in the fluorescence spectra were observed during silver binding to phycocyanin.
