Fluorescence intensity of 0.5 mg/ml FITC-tagged materials: (a) FITC-CNF and (b) FITC-CNC. The samples are exposed to excitation of 470 nm for one hour. The standard deviations are obtained from 2 replicates (n=2). (c) Photobleaching impact of confocal laser scanning microscopy on FITC-tagged CNF (solid circles) and FITC-tagged CNC (open circles). Fluorescence intensities were recorded every 5 minutes and are normalized against the values at t = 0 min.
