Three-dimensional scaffolds are often implanted or injected into the body as part of the process of tissue engineering. They have many uses: to target cancers with localised drugs, repair the effects of trauma or disease and maybe even to help regrow entire organs and bones. Much of the miniature scaffolding in use today is purely natural in origin. Many commercially available scaffolds use material normally found in the human body, harvested from animals or human donors. Others have more exotic origins, such as spider webs, silk, algae, seaweed and the chitinous shells of crabs and shrimp. Scaffolds made from these natural materials tend to have good "biocompatibility"--the ability to play well with the body's own cells--and usually biodegrade gracefully when their work is done. But they have drawbacks, too. Biological materials vary from batch to batch, can be hard to obtain, may carry disease and can break down too quickly in the hot, moist environment inside the body. Purely synthetic materials are not always a perfect alternative. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
