title: Fluorescent supramolecular nanoparticles signal the loading of electrostatically charged cargo.
abstract: Fluorescently labeled supramolecular nanoparticles (SNPs) were used to study the effects of their loading with oppositely charged cargo. SNPs shrank until neutralization, upon which they destabilized and aggregated. Using a dye-labelled guest, FRET occurred between the SNPs and a dye-labeled cargo. This effect may allow the development of responsive imaging and drug delivery vehicles.
