Abstract
The invention relates to composites comprising a polysaccharide gelled within pores of a foam, methods of preparation, and uses thereof, for example, in biomedical applications such as cell culture media and implants, controlled release delivery systems, food applications, industrial applications, and personal care applications such as cosmetic and oral hygiene. The composites of the present invention are simple to formulate using few steps and are useful for entrapping heat-sensitive components, such as cells, drugs, flavors or fragrances within the polysaccharide gel. In addition, the invention provides for a composite able to gently immobilize fragile components, such as living cells, without exposing such components to shear forces.
