Abstract: The present invention relates to hydrogels comprising a plurality of amphiphilic peptides and/or peptoids capable of self-assembling into three-dimensional macromolecular nanofibrous networks, which entrap water and form said hydrogels, wherein at least a portion of said plurality of amphiphilic peptides and/or peptoids is chemically cross-linked. The present invention further relates to methods for preparing such hydrogels and to various uses of such hydrogels, e.g. as cell culture substrates, for drug and gene delivery, as wound dressing, as an implant, as an injectable agent that gels in situ, in pharmaceutical or cosmetic compositions, in regenerative medicine, in tissue engineering and tissue regeneration, or in electronic devices. It also relates to a method of tissue regeneration or tissue replacement using a hydrogel in accordance with the present invention.
