Nature has produced materials with characteristics and functioning well beyond the engineered materials. Its hierarchical structure has been primarily associated with the incredible efficiency of biological materials, including their exceptional qualities that rely on weak constituents, high performance per unit mass, and numerous functionalities. Because of the unique properties and functions, biological materials are absolutely necessary to study life sciences. Tissues, biomolecules, and cells are some of these materials. Materials with mechanical qualities and biocompatibility such as collagen, keratin, and cellulose are very essential to many biological processes. The hierarchical structure allows multifunctionality and situational adaptation at molecular and macroscopic levels. Recent advances in biotechnology and materials science enabled development of biomimetic materials, which imitate the properties of true biological materials that can be used in tissue engineering, drug delivery systems, and medical implants. The relationships between structures of biological materials and properties can help in understanding the mechanisms behind biocompatibility, resilience, and adaptability. Furthermore, biological materials play a vital role in the development of gentle, sustainable, and environmentally sound materials. A wide range of research on biological and bioinspired materials can be analyzed from mechanical and functional perspective. The development of bioinspired materials utilizes principles of biological system to enhance material performance for practical applications including, civil, marine, aerospace, and medical engineering. Bioinspired materials are now playing a significant role in encouraging advancements and development in the contemporary materials industry despite the obstacles.
