Role of processing parameters on surface and wetting properties controlling the behaviour of layer-by-layer coated nanoparticles

Wetting phenomena at surfaces and interfaces is an important field of research with numerous commercial applications. As example, superhydrophobic surfaces are used as self-cleaning, antibiofilm forming and antimicrobial materials nowadays. Given the potential impact, creating surfaces with tailored wetting characteristics employing various fabrication techniques is of great interest. One very promising fabrication technique, for creating such materials is the layer-by-layer (LbL) self-assembly. LbL is a versatile technique allowing incorporation of different types of drugs and materials and the ability to coat substrates of complex geometries. This review summarises recent progress in preparation of Layer-by-layer constructs and a role of surface and wetting parameters in this technique. Effect of various physicochemical properties on LbL construct characteristics also were discussed.
