abstract = {The ability to control and direct mass transport of fluids and molecular components through soft biomaterials is of importance in a wide range of applications. Alginate is a biocompatible, renewable polymer source extracted from seaweed. The readily available anionic polysaccharide find commercial use in diverse areas such as wound care, pharmaceutics and food. Alginate forms a gel by rapid crosslinking with di- and tri-valent ions [1]. In this work we have used two different ways to introduce the multivalent ions that act as ion bridges between alginate. The methods are the "internal setting" [1] of the gels giving macroscopically homogeneous gels and “directed external” gelation [2] of the alginate giving rise to anisotropic growth of open capillaries running through the gel, see Figure 1. 

Our aim was to relate microstructural differences in the gels prepared by different methodologies to mass transport properties, and to determine the effect of various ions on the formation of channels.

Although the same amount of calcium ions was present the porous calcium alginate gel had a local diffusion significantly higher compared to the corresponding gel without capillaries. The diameter and amount of capillaries could be tailored by using different types of ions from tenth to several hundreds of micrometers. By varying the preparation method and the type of ion for gelation we are able to form a biomaterial with different mass transport properties according to our needs. },
