Confocal laser scanning micrographs of HeLa cells incubated with rapidly degrading hexnut particles (green) and nondegrading hexnut particles (red). Micrographs (A–C) highlight the phases of particle degradation: swelling (a), fragmentation (b), and complete degradation (c). The nondegradable particles showed no change when exposed to intracellular conditions (d). Scale bar represents 10 μm for all images. Reprinted with permission from ref 38.
