    • The differences between OPE-2 complexes with dsDNA, CMC, and CMA may be caused by the size difference in the scaffolds and possibly by the ionic strength difference. CMC and CMA are larger (naturally occurring cellulose has degrees of polymerization higher than 10000) than dsDNA used in these experiments for which the largest number of base pairs is 32. The investigations in this study indicate the extent of complex fluorescence increases with an increase in the number of bases in the DNA. The present experiments were carried out in 25 mM phosphate buffer solution, whereas the self-assembly between OPE-2 and CMC or CMA was measured in water. We have found in the higher ionic strength PBS the complexes between OPE-2 and CMC and CMA exhibit similar spectra to those observed in water, but the extent of fluorescence increase is lower
