Fabrication of sapeptide scaffolds. The sapeptide dissolved in water was injected through a device (two pieces of thin wire spaced 5 mm apart are sandwiched between two glass slides) into PBS to produce a tape-shaped macroscopic sapeptide scaffold that was stained with Congo red (A). The dimensions of the tape shown in A are approximately 8 cm in length, 0.5 cm in width, and 0.3 mm in thickness. The sapeptide scaffold was fabricated as a rope under similar conditions when the aqueous sapeptide solution was introduced into PBS using a 3-ml syringe (B). The dimensions of the sapeptide scaffold string shown are 18 cm in length and 2 mm in diameter. Sapeptide scaffold was fabricated as a sheet (C). Part of the sheet was removed and used for cell attachment experiments. The scale in centimeters is shown below the sheet structure.
