Alginate Foam There are numerous biomedical uses for biomaterials made in the form of films, fibers, foams and gels. It is highly desirable that these materials exhibit biocompatibility and biodegradability when required. One such material is alginate. Of particular interest recently are alginate foams. FMC — NovaMatrix are opening several patents for ultra-pure alginate foams developed by NovaMatrix for customers use and development.

These foams can be flexible and pliable, yet can be engineered to provide structural integrity and tensile strength if required. Unlike other foams, alginate foams using ultrapure PRONOVA alginates can be formulated to be biocompatible, do not exhibit handling brittleness, and could be manufactured without the need for expensive equipment, and processes such as freeze drying.

PRONOVA alginate would allow for low endotoxin levels and the foam may be sterilized using common sterilization techniques. For example, the alginate foams can have several benefits as immobilization matrices. Materials such as drugs, particulates, living cells, etc. For cell immobilization this is a quick and gentle technique; the living cells are immobilized from the start in a three dimensional network.

As such, they tend to readily proliferate in three dimensions within the foam matrix. The cells can also be readily harvested later for further study by using chelating agents to dissolve away the foam.

Human Chondrocytes immobilized in alginate foam for 31 weeks. However, there can be high formulation flexibility of alginate foams and they can be engineered to meet the requirements of specific applications. Among the physical foam properties that can be controlled are pore size, strength, degradation rate, absorption rate, absorption capacity and density. NovaMatrix is capable of providing you with the ultrapure grades of alginates that can be used to develop an alginate-based foam tailored to your specific interest and application requirements.
