Claim:
1. A stratified biostructure, comprising at least two hydrogel membranes, each said hydrogel membrane comprising a hydrogel, said hydrogel comprising a plurality of tetramer amphiphilic peptides capable of self-assembling into three-dimensional macromolecular nanofibrous networks, which entrap water and form said hydrogel, the tetramer amphiphilic peptides having the general formula: wherein Z is an N-terminal protecting group, P is 0 or 1; X is, at each occurrence, independently selected from an aliphatic amino acid, n is 2, Y is a hydrophilic amino acid, m is 1, AA Z′ is a C-terminal protecting group, and q is 0 or 1, wherein at least a portion of said plurality of tetramer amphiphilic peptides is chemically cross-linked.
