Structural and Functional Materials

Building high-performance materials with numerous uses can be greatly influenced by natural biological materials. Bioinspired materials have developed quickly during the past few decades by imitating their chemical makeups and hierarchical structures. Silk is gaining popularity as a very promising biosourced raw material because of its superior mechanical qualities, advantageous adaptability, and outstanding biocompatibility. We give a summary of the most recent developments in silk-based bioinspired structural and functional materials in this article. We begin with a succinct overview of silk, covering its origins, properties, production, and forms. The creation and use of silk-based materials that replicate four common biological materials—bone, nacre, skin, and polar bear hair—are next briefly discussed. Finally, we talk about the field's present difficulties and potential for the future.
