Polysaccharide-based hydrogels have emerged as indispensable materials in tissue engineering and wound healing, offering a unique combination of biocompatibility, biodegradability, structural versatility. Indeed, their three-dimensional polymeric network high water content closely resemble the natural extracellular matrix, creating microenvironment for cell growth, differentiation, regeneration. Moreover, intrinsic tunable chemical structure, non-toxicity, minimal immunogenicity make them optimal candidates prolonged drug delivery systems. Notwithstanding numerous advantages, these polysaccharide-based are confronted with setbacks such variability material qualities depending on source, susceptibility to microbial contamination, unregulated absorption, inadequate mechanical strength, unpredictable degradation patterns which limit efficacy real-world applications. This review summarizes recent advancements application hydrogels, including cellulose, starch, pectin, zein, dextran, pullulan hyaluronic acid innovative solutions delivery, engineering, regenerative medicine. Future research should concentrate optimizing hydrogel formulations enhance effectiveness medicine antimicrobial therapy.

This study utilized the Schiff base reaction as a chemical bonding method to successfully graft 2-aminopyridine onto oxidized sodium alginate, resulting in formation of modified alginate (OSM). Subsequently, OSM/polyacrylic acid (OSM/PAA) hydrogel was synthesized via thermally initiated free radical polymerization process and evaluated an adsorbent for removal heavy metal ions from wastewater. Comprehensive characterization prepared samples performed using FT-IR, SEM, TGA. The influence temperature, pH, dosage, contact time, ion concentration on adsorption capacity OSM/PAA simulated wastewater thoroughly investigated. Additionally, detailed analysis thermodynamics, kinetics, mechanisms conducted. Experimental results indicated that at 25 °C, pH 5.0, dosage 0.4 g/L, maximum capacities Cu(II), Zn(II), Ni(II) were 367.64 mg/g, 398.4 409.83 respectively. These findings suggest by is spontaneous, heterogeneous with significant potential practical applications treatment.

Coral reefs play an essential ecological role in maintaining marine water quality by naturally filtering contaminants. This study investigates the quantitative capability of coral reef ecosystems to reduce waterborne pollutants using biologically mediated processes. A systematic methodology, combining situ observations, laboratory simulations, and analytical modeling, was adopted determine filtration efficiency reefs. Remote sensing photogrammetry characterized morphology, while microbial consortia transformations polyp assimilation rates were quantified biochemical assays. Results demonstrated significant nutrient uptake polyps, particularly nitrogenous compounds, with higher removal efficiencies under stable salinity conditions. Temperature-induced stress found functionality. Enhanced sediment attenuation near structures improved coastal transparency. The integration vegetation buffers adjacent further augmented pollutant efficiency, combined strategies for effective pollution management.

Water scarcity and heavy metal pollution are significant challenges in today's industrialized world. Conventional remediation methods often inefficient energy-intensive, produce chemical sludge. To address these issues, we developed a bioinspired, carbohydrate-containing polymer system for efficient selective removal. Using ring opening metathesis polymerization, synthesized polymers bearing amphiphilic glucuronate side chains capable of selectively binding cations mixed media. In samples containing high concentrations metals (>550 ppb), rapidly form filterable precipitate upon capture, reducing the concentration cation to <1.5 ppb within 3 min, as measured by inductively coupled plasma mass spectrometry. This effectively removes cadmium ions from highly contaminated solutions levels below Agency Toxic Substances Disease Registry limit Cd2+ drinking water both Pb2+ lake spiked with trace amounts metal. Acidification triggers protonation groups, releasing resolubilizing polymer. capture-and-release process can be repeated over multiple cycles without loss capacity. As such, this study introduces novel class recyclable materials pH-responsive properties, offering potential applications beyond.
