DNA monolayers with upright orientation release drugs more quickly. When the longer single-stranded DNA is used, the drug release is slowed even further. However, even upright DNA layers provide a barrier to drug diffusion at longer sequence lengths. We hypothesize that it is the architecture of the DNA layer, influenced by the folded or upright orientation of individual DNA molecules, that affects the free diffusion of the drug away from the AuNP surface. This mechanism may improve the biological availability of many surface-
