Versatile photo-processing of ELP-D materials. (A) Drop cast, free-standing ELP-D film (t~50 µm), which (B) has sufficient strength to hold a 4.5 g mass. (C) Tensile stress-strain curve for ELP-D drop cast film, Young’s modulus ~250 MPa. (D) SEM image of spin coated photocrosslinked ELP-D thin film (t~500 nm) showing uniform protein coverage. (E) Protein mass of thin films is controlled by processing at specific spin coating speeds. (F) Bulk, three-dimensional ELP-D scaffold (t~2 mm, d~4.5 mm).
