Introduction
Biomaterials can be defined as any material, engineered, or natural in origin, that can supplement human body parts partly to sustain the standard of human life. These biomaterials should be secure, dependable, inexpensive, and biologically suitable and should not link with the host’s biological system. Synthetic materials are usually metallic, polymeric, and ceramic, or can be composite. These biomaterials are derived from marine microbes like fungi and bacteria, vertebrates like fish, mammals, and invertebrates like corals. Fish skin is a rich source of collagen and bone for hydroxyapatite (Boaventura, et al., 2020) Marine algae such as blue-green algae are reported as an excellent source of various polysaccharides, it includes alginate, chitin, chitosan, and fucoidan (Venkatesan et al., 2015). Studies have found that these marine biomaterials, such as surgery, tissue engineering, and medicaments, are frequently used for biomedical applications. Marine Biomaterials in accordance with chemical nature are categorized into six classes. (Figure 1).Figure 1: Classification of Marine Biomaterials based on chemical nature
