Book excerpt: "Polymer-Based Wound Treatment from Sargassum" is a comprehensive book written by M. Muthulakshmi that focuses on the potential use of natural polymers extracted from marine algae, specifically Sargassum Miyabei Yendo, as a promising material for wound treatment. The book provides an in-depth analysis of the properties of Sargassum polymer and its applications in wound healing, tissue repair, and wound management. The book covers various aspects of Sargassum polymer, including extraction, purification, and characterization. The author also explores different forms of drug delivery systems such as nanospheres, hydrogels, and sheets that can be used for wound healing. The use of animal models in both in vivo and in vitro studies is also discussed, providing insights into the biocompatibility and biodegradability of Sargassum polymer. The book also highlights the potential of Sargassum polymer as a natural alternative to synthetic materials in wound care management. The author explores the various wound treatment alternatives and natural products available in the market, and how Sargassum polymer can play a significant role in tissue engineering and wound regeneration. The controlled release of drugs, drug encapsulation, and drug carriers for wound care are also addressed in the book. Finally, the book delves into wound infection, inflammation, microbiome, biofilm, and antimicrobial therapy, emphasizing the importance of wound nanotechnology and drug delivery to wound in enhancing wound healing mechanisms. Overall, "Polymer-Based Wound Treatment from Sargassum" is a valuable resource for researchers, clinicians, and students in the field of biomedical materials, biotechnology, and wound care.
