Dynamics of normalized fluorescence intensity of single-fibers. Each curve (▵, ●, ◆, □) represents a single-fiber. The kinetics of single-fiber assembly was different. The graph shows that polymerization of single-fibers reach a maximum intensity at different stages of network formation. The fluorescence intensity of single-fibers was measured and normalized by the maximum of intensity of each fiber. The first arrow () shows the gel point measured by eye. The second arrow (↓) shows the time when turbidity curve reached a plateau.
