Laminarin, a sulfated β-glucan derived from brown macroalgae, (2-10 kDa) is becoming of interest because of its biodegradability and chemical versatility to bind a wide range of pollutants. This guide synthesizes advances in innovative, environmental-friendly, and high-yield extraction methods that aim to maximize yield and decrease energy and processing costs. Then it reviews the functionalization strategies (both physical and chemical) of laminarin such as grafting, crosslinking, incorporated nanoparticles and forming composites of laminarin with other polymers, and discusses these unique strategies to dramatically enhance removal of dyes, heavy metals, pharmaceuticals, and emerging contaminants from wastewater. The structure-property relationships are presented to illustrate how branching degree, sulfate groups, and introduced functionalities dictate adsorption capacity, selectivity, diffusion behavior, and reusability. Economic estimates indicate that green-extracted, moderately functionalized laminarin has better economic competitiveness than traditional adsorbents and can be scaled. Notable limitations including feedstock variability, constraints on production at scale, and unmodified laminarin's instability in harsh effluents are critically appraised. To mitigate these limitations, the review provides future pathways towards hybrid nano-laminarin systems, stimuli-responsive materials, and circular-economy regeneration approaches. The intersection of sciences, engineering, and sustainability deem this review a reference for the development of next-generation laminarin-based materials for efficient and green wastewater purification.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"220 ","pages":"Article 106618"},"PeriodicalIF":5.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145885313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These barriers eliminate the accumulation of foreign substances inside the body and may inhibit the active absorption of therapeutic substances. Thus, the design of an appropriate delivery system must integrate features that tend to enhance the bioavailability of the drug and controlled medication release towards the target area, thereby overcoming numerous ocular barriers. In recent years, chitosan, a naturally occurring polymer, has been mucoadhesive, biologically compatible, and biodegradable, making it the subject of extensive investigation. It has special physicochemical qualities, including easy chemical modification, pH-sensitive solubility, and improved permeability capabilities. These characteristics render it an optimal material for nanoparticles, hydrogels, gels, <em>in situ</em>, and ocular drug delivery inserts development. This review examines the obstacles related to ocular drug delivery and recent progress for chitosan-based ocular systems formulation designed to enhance drug retention, corneal permeability, and prolonged drug release.

Integrating lignin with photocatalytic ferrite particles not only improves the catalytic efficiency of nickel ferrite, but also extends its applicability towards fluorescence-based pollutant detection. Detailed characterizations, including XRD, FT-IR, FE-SEM, HR-TEM, XPS, BET, VSM, UV-DRS analyses, were carried out to investigate the structural, morphological and optical properties of the devised composites.

Moreover, LNF2 was successfully deployed as fluorescent sensor, enabling sensitive detection of DOX and SO in aqueous samples with detection limits of 1.422 μM and 1.273 μM, respectively.

The fabrication process involved first preparation of a homogeneous mixture solution of PVA, glycerol, graphite, and CaCl₂ in deionized water. Then Na₂CO₃ solution was slowly added under stirring.
