✦ Synopsis
We utilize the dynamic quenching of the triplet state of methylene blue by molecular oxygen to observe changes in the rate at which oxygen can penetrate the helix as a function of base-pair composition. The results indicate that the interior of the oligonucleotide dAdT is more accessible than dGdC to small molecules such as dioxygen.
