Inside Cover: Nanostructure‐Dependent Ratiometric NIR Fluorescence Enabled by Ordered Dye Aggregation (ChemNanoMat 5/2016)

Nanoscale ordered aggregates of naturally derived bacteriochlorophyll dyes exhibit a remarkable 60 nm redshift in their NIR fluorescence. By controlling dye supramolecular assembly within a compact nanocarrier, the authors demonstrate a novel photophysical mechanism for evaluating nanostructures. Ratiometric fluorescence imaging distinguishes intact and disrupted nanocarriers in biological environments, which has practical applications for theranostic nanomedicine.
