We developed and produced the chimera protein by linking AFPIII, an ice-binding protein, with CBM3a, a CNC-binding protein. As the suspension freezes, the CNC chains self-organize into a reinforcing network between the ice crystals. This structural enhancement limits crack propagation to typical pore sizes, allowing BioPykrete to avoid the brittle and sudden failure commonly associated with ice.
