We report an efficient and straightforward method to synthesize enantio-enriched N-unprotected α-amino acetals via ruthenium-catalyzed direct asymmetric reductive amination. The α-amino acetal products are versatile and valuable platform molecules that...
In this work, homo-FRET (Förster resonance energy transfer between the same kind of fluorophores) taken place in a hetero-FRET (FRET between two different fluorophores) systems can effectively improve the energy...
By arranging fluorophores in a directional way on a 2D DNA nanosheet that transfers energy from the initial donor to the acceptor through homogeneous Förster resonance energy transfer (homo‐FRET), it is found that the photonic wires (PWs) based on cascade long‐range resonance energy transfer (LrRET) up to 15.6 nm can be effectively achieved through the rational selection of the fluorophores and the adjustment of their position with different distance. Then, logic control of directional energy transfer is achieved with the blocking of the energy transfer pathway, making two tumor‐associated microRNA (miRNA) inputs produce an obvious output with the association of tumor diagnosis only when they present simultaneously. This research provides a new thought for development of PWs on 2D DNA nanosheets and a smart application of LrRET‐based DNA AND logic control of intracellular miRNA imaging and tumor cells recognition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
