As nations strive for cleaner manufacturing processes, biomaterials are emerging as a pivotal element in materials engineering. These innovative materials not only promise sustainability but also enhance the functionality of products across various sectors.
Biomaterials are defined as materials originating from natural, synthetic, or hybrid sources, designed to interact safely with biological systems and the environment. They can be derived entirely or partially from biological sources, or engineered through biological processes to replace or complement traditional materials.
The utilization of biomaterials is expanding rapidly across diverse fields, including packaging, textiles, construction, and healthcare. In modern biomedicine and bioengineering, biomaterials play a crucial role, with their design driven by specific application requirements and associated trade-offs.
The contemporary field of biomaterials integrates various scientific disciplines, including physics, chemistry, medicine, and biology, alongside materials science and tissue engineering. This multidisciplinary approach enhances the development of novel materials that meet the complex demands of modern applications.
Biomaterials can be broadly categorized into three main types:
As the demand for sustainable solutions increases, biomaterials are set to redefine the future of engineering and product development, leading to greater environmental responsibility and innovative applications.
