Characterization of ddPDI aggregates prepared via combined SPI and SSVA. (a) Fluorescence intensity heatmap image and (b) modulation depth (M) heatmap image of ddPDI aggregates. (c) Representative intensity modulation traces with fits of ddPDI aggregates for putative H-dominant aggregates originating from SSVA alone (red), H-dominant aggregates originating from seeded growth (green), and J-dominant aggregates originating from seeded growth (blue). (d) M values vs. fluorescence intensities for each assessed aggregate. Ellipses are drawn by eye and suggest 3 groupings distinguished by final intensity as well as M value, with colors corresponding to those in (c). Arrows correspond to the aggregates identified with arrows of the same color in (a) and (b). (e,f) Representative emission spectra of H-dominant aggregates originating from the SSVA process (red), H-dominant aggregates originating from seeded growth (green), and J-dominant aggregates originating from seeded growth (blue). Each pair presented in (e) and (f) were collected in the same field of view.
