A technique for the preparation of polyacrylamide hydrogels with a gradient in Young's modulus from 150 kPa down to 20 kPa within a length of 10 mm, is presented. Upon surface treatment with collagen I, the produced hydrogels are bioactive and human foreskin fibroblasts feel the strength of the underlying material. After 2 hours, HFFs on the soft end of the sample are still round and small, while they are already well spread on the stiff end of the substrate.
