Abstract: End-to-end intermolecular interaction between double-stranded DNAs grafted onto individual nanoparticles is regulated by terminal base pairing/unpairing triggered by the photo-isomerization of an azobenzene moiety inserted in the vicinity of the DNA terminal. This is the… read more here.

DOI: 10.1039/d0ra06627c
Abstract: The application of azobenzene (AZO) as a kind of photo-switch is restricted by its excitation source, i.e., UV light. Hence, visible light-driven azobenzene-based photo-switching is needed and has been designed in the work. In order… read more here.

Abstract: The self-trapping nano-loop structures of [1]rotaxanes exhibited multiple Förster resonance energy transfer (FRET) patterns via dual and sequential locking/unlocking of pH-gated and UV exposure processes. As a tightened and constrained nano-loop in the acidic condition,… read more here.
