The most abundant structural protein in the locust mandible (CPH-1) was identified and revealed to be vital for the reinforcement of mandible cuticles. CPH-1 can self-assemble into an extraordinarily stiff film, which outperforms most protein-based materials. This study not only represents a universal reinforcing mechanism of insect cuticle but also provides a potent starting material for sustainable materials.

蝗虫下颌骨中的主要结构蛋白能够通过分层自组装形成异常坚硬的材料

蝗虫下颌骨中最丰富的结构蛋白 (CPH-1) 被鉴定出来，并被证明对于强化下颌骨角质层至关重要。 CPH-1 可以自组装成异常坚硬的薄膜，其性能优于大多数蛋白质基材料。这项研究不仅代表了昆虫角质层的普遍强化机制，而且还为可持续材料提供了有效的起始材料。
