The development of biomaterials is not a new area of science, having existed for around half a century. The study of biomaterials is called biomaterials science. It is a provocative field of science, having experienced steady and strong growth over its history, with many companies investing large amounts of money into the development of new products. Biomaterials science encompasses elements of medicine, biology, chemistry, tissue engineering and materials science.
Algae (pronounced /ˈældʒiː,ˈælgiː/; singular alga /ˈælɡə/, Latin for "seaweed") are a large and diverse group of simple, typically autotrophic organisms, ranging from unicellular to multicellular forms. The largest and most complex marine forms are called seaweeds. They are photosynthetic, like plants, and "simple" because they lack the many distinct organs found in land plants. For that reason they are currently excluded from being considered plants.[3]
Allotransplantation (allo- from the Greek meaning "other") is the transplantation of cells, tissues, or organs, sourced from a genetically non-identical member of the same species as the recipient.[1]. The transplant is called an allograft or allogeneic transplant or homograft. Most human tissue and organ transplants are allografts.
Amino acids are molecules containing an amine group, a carboxylic acid group and a side chain that varies between different amino acids. These molecules are particularly important in biochemistry, where this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent.[1] In the alpha amino acids, the amino and carboxylate groups are attached to the same carbon atom, which is called the α–carbon. The various alpha amino acids differ in which side chain (R group) is attached to their alpha carbon. These side chains can vary in size from just a hydrogen atom in glycine, to a methyl group in alanine, through to a large heterocyclic group in tryptophan.An exoskeleton is an external skeleton that supports and protects an animal's body, in contrast to the internal endoskeleton of, for example, a human. Some animals, such as the tortoise, have both an endoskeleton and an exoskeleton. In popular usage, many of the larger kinds of exoskeletons are known as "shells".
Animals are a major group of mostly multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life. Most animals are motile, meaning they can move spontaneously and independently. All animals are also heterotrophs, meaning they must ingest other organisms for sustenance.Aragonite is a carbonate mineral, one of the two common, naturally occurring crystal forms of calcium carbonate, CaCO3 (The other form is the mineral calcite.) It is formed by biological and physical processes, including precipitation from marine and freshwater environments.Autotransplantation is the transplantation of organs, tissues or even proteins from one part of the body to another in the same individual. Tissue transplanted by such "autologous" procedure is referred to as an autograft or autotransplant. It is contrasted with xenotransplantation (from other species) and allotransplantation (from other individual of same species). A common example is when a piece of bone (usually from the hip) is removed and ground into a paste when reconstructing another portion of bone.
