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
