Photo-controlled reversible secondary self-assembly of supramolecular nanosheets and their drug delivery behavior
2019
Supramolecular nano-drug delivery systems with stimuli-responsive features have attracted extensive attention in photodynamic therapy. In this work, a new kind of photo-controlled reversible two dimensional (2D) nanosheet was constructed by cucurbit[8]uril (CB[8])-mediated ternary complexation with lanthanide complexes, azobenzene quaternary ammonium salt and sodium dodecyl sulfonate, which exhibited rapid morphological transformation and high drug loading capacities. The constructed supramolecular secondary self-assembly system has become a very promising candidate as a drug nanocarrier.
