title: Highly efficient remote controlled release system based on light-driven DNA nanomachine functionalized mesoporous silica.
abstract: An intelligent photoswitchable single-molecule nanomachine with DNA hairpin-loop structure was designed by the incorporation of azobenzene groups in DNA sequences, which was studied by fluorescence resonance energy transfer (FRET) and attached onto the surface of mesoporous silica. Based on the photo-induced conformational transformation of DNA, highly efficient controlled release was realized.
