�Simultaneous Spray Coating of Interacting Species� (SSCIS): a new method to coat surfaces. SSCIS is inherited from the Spray-assisted Layer-by-Layer (LbL) deposition which attracted considerable attention since 2000. SSCIS is a simultaneous deposition of interacting components on a surface leading to a fast buildup of non-layered coatings. A comparison between SSCIS and Spray-assisted LbL method will be made using biodegradable natural polysaccharide coatings.We will focus on the influence of the sprayed charge ratio on the film growth rate, the rules driving the construction and the morphologies. A correlation between the film growth and the size of the complexes, leading to the films construction, is established.The potential of these polysaccharide films in the field of biomaterials is demonstrated by studying their biocompatibility.The SSCIS method appears to be a promising avenue towards fast and easy industrial non-layered coatings construction.
