Polymers, Journal Year: 2022, Volume and Issue: 14(6), P. 1080 - 1080

Published: March 8, 2022

The sharp increase in the use of cellulose seems to be increasing demand wood; much more research related sustainable or alternative materials is necessary as a lot arable land and natural resources unsustainable. In accordance, attention has focused on bacterial new functional material. It possesses three-dimensional, gelatinous structure consisting with mechanical thermal properties. Moreover, while plant-originated composed cellulose, hemi-cellulose, lignin, attributable composition pure nanofiber mesh spun not elimination other components. due its hydrophilic nature caused by binding water, consequently being hydrogel well biocompatibility, it only used medical fields including artificial skin, cartilage, vessel, wound dressing, but also delivery; some products have even been commercialized. addition, widely various technologies food, paper, textile, electronic electrical applications, considered highly versatile green material tremendous potential. However, many efforts conducted for evolution novel sophisticated environmental affinity, which accompany empowerment enhancement specific this review article, we summarized industry status regarding BC contemplated potential BC.

Progress in Hydrogels for Skin Wound Repair

Macromolecular Bioscience, Journal Year: 2022, Volume and Issue: 22(7)

Published: April 7, 2022

Abstract As the first defensive line between human body and outside world, skin is vulnerable to damage from external environment. Skin wounds can be divided into acute (mechanical injuries, chemical surgical wounds, etc.) chronic (burns, infections, diabetes, etc.). In order manage wound, a variety of wound dressings have been developed, including gauze, films, foams, nanofibers, hydrocolloids, hydrogels. Recently, hydrogels received much attention because their natural extracellular matrix (ECM)‐mimik structure, tunable mechanical properties, facile bioactive substance delivery capability. They show great potential application in repair. This paper introduces anatomy function skin, process healing conventional dressings, then composition construction methods Next, this necessary properties repair latest research progress hydrogel for Finally, future development goals materials field are proposed.

A Brief Review on the Development of Alginate Extraction Process and Its Sustainability

Sustainability, Journal Year: 2022, Volume and Issue: 14(9), P. 5181 - 5181

Published: April 25, 2022

Alginate is an attractive marine resource-based biopolymer, which has been widely used in pharmaceutical, food and textile industries. This paper reviewed the latest development of conventional alternative processes for alginate extraction from brown seaweed. To improve yield product quality, various studies have carried out to optimize operation condition. Based on literature survey, most commonly protocol soaking milled seaweed 2% (w/v) formaldehyde, overnight, solid loading ratio 1:10–20 (dry weight biomass solution), then collecting acid pre-treatment with HCl 0.2–2% (w/v), 40–60 °C, 1:10–30 2–4 h. Next, residue extracted using Na2CO3 at 2–4% 2–3 h, ratio. Then liquid portion precipitated by ethanol (95%+) a 1:1 (v/v). Finally, output dried oven 50–60 °C. Novel methods ultrasound, microwave, enzymes extrusion improved properties, but financial benefits not fully justified yet. sustainable production alginate, it required promote cultivation, reduce water footprint, decrease organic solvent usage co-produce other value-added products.

Carrageenan-Based Compounds as Wound Healing Materials

International Journal of Molecular Sciences, Journal Year: 2022, Volume and Issue: 23(16), P. 9117 - 9117

Published: Aug. 14, 2022

The following review is focused on carrageenan, a heteroglycan-based substance that very significant wound healing biomaterial. Every biomaterial has advantages and weaknesses of its own, but these drawbacks are typically outweighed by combining the material in various ways with other substances. Carrageenans' key benefits include their water solubility, which enables them to keep periwound damp absorb exudate. They have low cytotoxicity, antimicrobial antioxidant qualities, do not stick bed, hence cause pain when removed from wounded region. When combined materials, they can aid hemostasis. This emphasizes using carrageenan for healing, including use several mixes improve properties.
