- The ability to construct thin films with controlled thickness on almost any type of surface is of great interestin many research fields. For biomedical applications, thin films on medical devices have been found toimprove the biocompatibility, reduce the immunological response, and deliver medical drugs locally. Thelayer structure is closely related to the function and efficiency of such films. During the last decades, it hasbeen shown that the layer-by-layer (LbL) assembly of charged macromolecules has created an inexpensiveroute to the formation of thin multilayer films, and the interest in using biomacromolecules (e.g., polysaccharidesand proteins) has emerged in recent years. The LbL technique offers unique opportunities forcontrolling the physical properties of thin surface layers, such as film thickness, chemical and elasticproperties, and stability. In this entry, we will focus on recent advances in the multilayer film area usingbiomacromolecules. We will discuss how different physicochemical properties of biomacromolecules andof the deposition solution affect the formation and structure of LbL-assembled multilayer. Finally, we willaddress some suggested applications for these biopolymer film coatings.
