a Surface morphology of the LbL-films of (CMCS/CS)n composed of 2.5, 5.5, 10.5, and 20.5 layer pairs using chitosan low molecular weight (CS LMW) or medium molecular weight (CS MMW). Note that all n values correspond to an uneven number of layers and so all films terminate with a layer of CMCS. b Surface morphology of the LbL-films of (CMCS/CS)n composed of 2, 5, 10, and 20 layer pairs at the initial pH solution using chitosan of low molecular weight (CS LMW) and medium molecular weight (CS MMW). The image dimensions are 2.5 × 2.5 μm2
