SEM morphology of (a) PDA modified Ti surfaces, (b) Ti-(Chi/OAlg)20, (c) the cross-section of (Chi/OAlg)20 films. (d) Water contact angles as a function of the number of layers. (e) UV absorbance of FITC-Chi/OAlg films with different numbers of bilayers: (from bottom to top) 1, 2, 3, 4, 6, 8 and 10. The inset shows the absorbance at 507 nm vs the number of bilayers.
