In the next stage of research we checked the morphology of the studied hydrogels. For this purpose, the gels were frozen rapidly in liquid nitrogen (-210°C), and then water was partially sublimated. The images showed that all peptides were highly organized, resembling a honeycomb (Fig. ). The morphology was porous and had apparently interconnected pores, and consisted of layers with spaces about 6-8 µm in height. The spaces were separated by thin membranous walls less than 0.1 µm thick.
