In Situ Swelling Behavior of Chitosan-Polygalacturonic Acid/Hydroxyapatite Nanocomposites in Cell Culture Media
Figure 3
AFM 3D topographic images of dry (a) and soaked Chi-PgA-HAP samples for 1, 2, 8, 24, and 48-day, respectively (b)–(f). Topographic changes are evident after soaking in cell culture media. Topographic features (ridges, valleys, and pits) appear in a random fashion during the initial soaking duration up to 8 days, and then, more gradual changes are observed during the longer soaking period up to 48-day, as seen in topographic images (e, f).
