Self-assembled DNA molecules conjugated to GaN semiconductor nanostructures for radiative decay engineering

This study aims to develop a highly luminescent biomaterial system that can be conjugated to weakly fluorescing biological molecules for the development of biosensors. The surface and interface properties of a hybrid semiconductor-metal-organic layered structures that affect the optical properties of the system for developing nanophotonic bioprobes is presented. The proposed strategy is dependent on resonant energy transfer between fluorescently labeled receptors via a metallic interface. The novelty of the approach lies in exploiting the link between bioconjugated DNA nucleosides sensing units with GaN quantum dots using fluorescent radiative decay engineering via resonant surface plasmon interaction.
