Prang et al . ( 2006 ) assessed the capacity of ACH gels to promote directed axonal regrowth in the injured mammalian CNS . The multivalent ions used to create the alginate-based ACH gels were copper ions, whose diffusion into the sodium alginate layers created hexagonally structured anisotropic capillary gels.
