Marine biomaterials have attracted significant attention in recent years due to their unique properties and potential for biomedical applications. Marine organisms, such as seaweeds and shellfish, produce a wide range of biomaterials that have biocompatibility, biodegradability, and mechanical strength, making them promising materials for various medical applications. The rapid growth of the marine biomaterials field has been driven by the need for innovative and effective biomedical materials.

One of the key areas of research in marine biomaterials is the optimization of material properties. Researchers are working to understand the properties of various marine biomaterials and how these properties can be harnessed to improve their performance in biomedical applications. For example, studies have shown that marine collagen has great potential for tissue regeneration due to its mechanical strength and biocompatibility. Alginate, a material derived from seaweed, has been shown to be effective in wound healing due to its ability to absorb water and promote the growth of new tissue.

Another important area of research in marine biomaterials is the development of new production methods. This research aims to improve the efficiency and sustainability of marine biomaterials production, making them more accessible and cost-effective. Researchers are exploring new techniques for the extraction and purification of marine biomaterials, such as chitin and alginate, to improve their quality and consistency.

In addition to optimizing material properties and production methods, researchers are also exploring new biomedical applications for marine biomaterials. One of the most promising areas of research is in drug delivery. Marine biomaterials, such as alginate, have been shown to be effective in delivering drugs directly to the site of an injury, improving the efficacy of treatments. Another promising area of research is in tissue engineering, where marine biomaterials are being used to create functional tissues and organs for transplantation. Polysaccharides belong to biological materials with carbohydrate backbone-based structures. In this review, we focus attention only on structural aminopolysaccharide chitin and selected polysaccharides of algal origin. Chitosan, an artificially produced derivate of chitin, was not the goal of our analytical research exclusively due to the existence of numerous reviews related to this biopolymer

Here are some of the key areas of progress in modern marine biomaterials research:

• Development of new materials: Researchers are continuously exploring new and diverse sources of marine materials, such as microalgae and invertebrates, to create new and improved biomaterials with unique properties. These new materials have potential for use in a wide range of biomedical applications, from drug delivery systems to wound healing and tissue regeneration.
• Improved characterization techniques: Advances in characterization techniques, such as spectroscopy, microscopy, and imaging, have allowed for a deeper understanding of the structure and properties of marine biomaterials. This has led to the development of new and improved materials with increased potential for biomedical applications.
• Enhanced performance: Researchers are developing new methods for modifying marine biomaterials to enhance their performance, such as improving their mechanical strength, biodegradability, and drug delivery properties. This has led to the development of new materials with increased potential for use in a wide range of biomedical applications.
• Increased understanding of biocompatibility: Research into the biocompatibility of marine biomaterials has increased, allowing for the development of safer and more effective materials for biomedical applications. This has led to the development of new materials with increased potential for use in a wide range of biomedical applications, from wound healing and tissue regeneration to drug delivery systems and medical implants.
• Integration with other materials: Researchers are exploring the integration of marine biomaterials with other materials, such as metals and polymers, to create new materials with enhanced properties and improved performance for biomedical applications. This has led to the development of new materials with increased potential for use in a wide range of biomedical applications, from wound healing and tissue regeneration to drug delivery systems and medical implants.

In conclusion, research progress in marine biomaterials has been significant in recent years, leading to the development of new materials and improved methods for their production and characterization. The future of marine biomaterials research is promising, with the potential to unlock the full potential of these materials for a variety of biomedical applications. Through continued research and development, marine biomaterials have the potential to greatly improve human health and quality of life.
