Self-assembling materials

Definition

Self-assembling materials are substances that can organize themselves into structured patterns or forms without external guidance, often inspired by natural processes. These materials leverage molecular interactions to achieve their arrangement, mimicking how biological systems like proteins and cells form complex structures autonomously. This self-organization can lead to innovative manufacturing techniques that enhance efficiency and sustainability in production.
