Layer-by-Layer Films from Wine: An Investigation of an Exponential Growth Process

Layer-by-Layer Films from Wine: An Investigation of an Exponential Growth Process

We report on the preparation and study of layer-by-layer films of wine alternated with bovine serum albumin (BSA). We found that the exponential and/or linear growth of the films is dependent on the deposition time. Atomic force microscopy images were analysed using scale laws and the fractal dimens...
