    Gels are ubiquitous materials with broad applications in both scientific and industrial field. They can be described as dispersion systems, containing a solid dispersion phase interconnected into three-dimensional network. Inside this network, a liquid dispersion medium is entrapped. From mechanical point of view, gels are often described as materials with properties overlapping between solids and liquids. This means that at some specific conditions, gels can have properties of liquids (viscosity). Contrarily, under different conditions, they can act as solids (elastic response). These specific properties, together with their simple preparation procedure, biocompatibility, experimentally easy way of manipulation, usually simple mathematical description of shape and basic parameter, almost no effects of convection on internal transport and comparable speed of diffusion in comparison with liquids, make hydrogels a highly attractive material. Gels can be divided according to the type of used dispersion medium to hydrogels (where the liquid medium is water) and oleogels (the medium is oil).
