“…Though the molecular weight of the MVG alginate is over ten times less than that of the MVM alginate, the viscosities are similar (Figure S 5). This is not typical but may be due to differences in M/G ratios and G-block length, with higher G content and length alginates being typically stiffer and more viscous compared to alginates with a high-M content (Smith & Miri, 2011) (Nedovic & Willaert, 2013) (Jothisaraswathi & Rengasamy, 2006) (Schmid, Fariña, Rehm, & Sieber, 2016). It has been shown that varying the alginate purification method results in alginates with significantly different viscosities.…”

The current gold standard for aneurysm treatment is endovascular coiling. However, recurrence is observed in over 20% of cases. A novel hydrogel has been developed to treat aneurysms. This hydrogel is composed of a polymeric alginate, a novel ion releasing glass and glucono-delta-lactone. This is an internally setting alginate hydrogel, wherein the setting rate can be controlled by both the glass and the alginate chemistry. The aim of this work is to examine the effect of each component of the hydrogel and optimise the composition of the hydrogel, specifically the alginate molecular weight, M/G ratio and concentration. The effects of gamma sterilisation will also be examined. The results show that alginate concentration, chemical composition and molecular weight affect the compressive strength, working time, hardening time and deliverability of the hydrogel. Gamma irradiation of the alginate reduces the molecular weight, which has a negative effect on the usability of this hydrogel.

“…The second step is for the extract to be filtered, precipitated with calcium, and acidified to produce alginic acid. The insoluble alginic acid can then be treated with metallic carbonate, hydroxide, or oxide to produce the desired salt form of alginate [144].…”

Nowadays, biopolymers as intelligent and active biopolymer systems in the food and pharmaceutical industry are of considerable interest in their use. With this association in view, biopolymers such as chitosan, alginate, pectin, cellulose, agarose, guar gum, agar, carrageenan, gelatin, dextran, xanthan, and other polymers have received significant attention in recent years due to their abundance and natural availability. Furthermore, their versatile properties such as non-toxicity, biocompatibility, biodegradability, and flexibility offer significant functionalities with multifunctional applications. The purpose of this review is to summarize the most compatible biopolymers such as chitosan, alginate, and pectin, which are used for application in food, biotechnological processes, and biomedical applications. Therefore, chitosan, alginate, and pectin are biopolymers (used in the food industry as a stabilizing, thickening, capsular agent, and packaging) with great potential for future developments. Moreover, this review highlights their characteristics, with a particular focus on their potential for biocompatibility, biodegradability, bioadhesiveness, and their limitations on certain factors in the human gastrointestinal tract.

“…The alginic acid is obtained after the extract has been filtered, precipitated with calcium, and acidified. The required salt form of alginate is obtained by treating insoluble alginic acid with metallic carbonates, oxides, or hydroxides [ 87 ]. Alginate biocompatibility has been extensively studied, with data showing that oral administration of alginate does not trigger many immune responses, in addition to the finding that it is non-toxic and biodegradable [ 88 ].…”

Research regarding the use of biopolymers has been of great interest to scientists, the medical community, and the industry especially in recent years. Initially used for food applications, the special properties extended their use to the pharmaceutical and medical industries. The practical applications of natural drug encapsulation materials have emerged as a result of the benefits of the use of biopolymers as edible coatings and films in the food industry. This review highlights the use of polysaccharides in the pharmaceutical industries and as encapsulation materials for controlled drug delivery systems including probiotics, focusing on their development, various applications, and benefits. The paper provides evidence in support of research studying the use of biopolymers in the development of new drug delivery systems, explores the challenges and limitations in integrating polymer-derived materials with product delivery optimization, and examines the host biological/metabolic parameters that can be used in the development of new applications.
