Their research has been featured on the cover of the current issue of the journal ACS Photonics (May 20, 2015: Vol. 2, Iss. 5).
DNA-based nanostructures are being extensively explored as promising building blocks in the design of optical devices and electronic circuitry. In this Article, Massey and co-workers studied a time-gated Förster resonance energy transfer cascade between fluorescent dyes along the length of a 15 nm DNA photonic wire. The cover illustrates the cascade initiated by UV excitation of a lanthanide complex at one end of the wire and terminated by dye emission at the opposite end. View article.
