Method | Fresh stock solutions of Phe were prepared by dissolving Phe in distilled water at concentrations of 10, 25, 50, 100, and 150 mM. Fibril structure formed by following two techniques: (1)Conventional drop-casting: 3 mL of Phe–Phe solution was dropped on a clean stainless steel substrate and allowed to dry at 25°C in a vacuum for 12 h prior to subsequent characterization; (2) Directional freeze-drying: 1.5 mL of Phe–Phe solution was pipetted into a 2 mL centrifuge tube. The tube was placed into liquid nitrogen or a 20°C or 80°C freezer | |
