Influenced by bone tissues, right here, we report a nonswellable gradient hydrogel with flexible technical properties via a simple acid-heat remedy for polyamide-based hydrogels. Both the hydrophilicity/hydrophobicity and crosslinking level of the solution are simultaneously managed by taking benefit of the transformation of amide groups to imide groups into the hydrogel. A gradient imide framework is created with a dense layer nearby the surface for the serum. The resultant
