A. Effect of hydrogel dipping time in polyelectrolyte solution at each deposition step for a (PLL/HA)4-PLLFITC film. The PEM film thickness increased significantly when hydrogel dipping time at each deposition step is increased. B. Effect of the number of layer pairs on the film thickness at constant solution-dipping time of 7 min. The PEM-film thickness increased significantly with the number of deposited layer pairs. Inset in A and B shows fluorescence intensity profile images of PLLFITC/HA films built on HA hydrogels in xz direction by CLSM (Students t-test, * p<0.05).
