Polymeric Materials Used for Immobilisation of Bacteria for the Bioremediation of Contaminants in Water

Polymers, Год журнала: 2021, Номер 13(7), С. 1073 - 1073

Опубликована: Март 29, 2021

Bioremediation is a key process for reclaiming polluted soil and water by the use of biological agents. A commonly used approach aims to neutralise or remove harmful pollutants from contaminated areas using live microorganisms. Generally, immobilised microorganisms rather than planktonic cells have been in bioremediation methods. Activated carbon, inorganic minerals (clays, metal oxides, zeolites), agricultural waste products are acceptable substrates immobilisation bacteria, although there limitations with biomass loading issue leaching bacteria during process. Various synthetic natural polymers different functional groups successfully efficient cells. Promise has shown macroporous materials including cryogels entrapped applications treatment biotechnology. cryogel polymeric gel formed at sub-zero temperatures through known as cryogelation. Macroporous hydrogels make scaffolds supports immobilising bacterial, viral, other The production composite possessing suitable mechanical chemical stability, porosity, elasticity, biocompatibility suggests that these potential candidates range within applied microbiology, biotechnology, research. This review evaluates tools contaminants wastewater.

Progress toward Hydrogels in Removing Heavy Metals from Water: Problems and Solutions—A Review

ACS ES&T Water, Год журнала: 2021, Номер 1(5), С. 1098 - 1116

Опубликована: Апрель 5, 2021

Hydrogels, as a new type of biomaterial with unique physical and chemical characteristics, have three-dimensional solid networks constructed by hydrophilic polymer chains. The superior swell-ability, biocompatibility, functionalization made them widely explored applied in the removal heavy metals from water. Due to potential threats metals, most wastewater systems control industrial discharges at multiple (e.g., 100 times higher) maximum contaminated levels drinking Nevertheless, how employ hydrogel adsorbent fabricated lab for expanded applications real treatment is still critical challenge. In this review, we scrutinize emphasize latest developments synthesis application hydrogels removing recycling particular, barriers restraining development scale-up are presented, accompanied corresponding solutions raised our point view. A detailed review started typical hydrogels. Afterward, innovative representative strategies computer-aided design synthesizing desired capacities discussed evaluated. Challenges perfecting outstanding properties improving anti-interference capability, accelerating adsorption rate, broadening operational pH range, enhancing selectivity, minimizing toxicity clarified. addition, mechanical strength, resource recovery, reusability well reasonable mass transfer models adsorber used engineering applications. We also shed light on further features expected

Chitosan/Alginate Hydrogel Dressing Loaded FGF/VE-Cadherin to Accelerate Full-Thickness Skin Regeneration and More Normal Skin Repairs

International Journal of Molecular Sciences, Год журнала: 2022, Номер 23(3), С. 1249 - 1249

Опубликована: Янв. 23, 2022

The process of full-thickness skin regeneration is complex and has many parameters involved, which makes it difficult to use a single dressing meet the various requirements complete at same time. Therefore, developing hydrogel dressings with multifunction, including tunable rheological properties aperture, hemostatic, antibacterial super cytocompatibility, desirable candidate in wound healing. In this study, series hydrogels were developed via hydrogen bond covalent between chitosan (CS) alginate (SA). These exhibited suitable pore size for cell adhesion. Chitosan endowed great cytocompatibility thus solved two primary problems early stage healing process. Moreover, sustained was further investigated after adding FGF VE-cadherin co-culture L929 EC 12 days. confocal 3D fluorescent images showed that cells spherical tended form multicellular spheroids, distributed about 40-60 μm thick hydrogels. Furthermore, significantly accelerate defected turn normal proper epithelial thickness new blood vessels hair follicles through histological analysis vivo findings mentioned above demonstrated CS/SA growth factors have potential as multifunctional incorporated antibacterial, culture repairing.

Polydopamine Biomaterials for Skin Regeneration

ACS Biomaterials Science & Engineering, Год журнала: 2022, Номер 8(6), С. 2196 - 2219

Опубликована: Июнь 1, 2022

Designing biomaterials capable of biomimicking wound healing and skin regeneration has been receiving increasing attention recently. Some biopolymers behave similarly to the extracellular matrix (ECM), supporting biointerfacial adhesion intrinsic cellular interactions. Polydopamine (PDA) is a natural bioadhesive bioactive polymer that endows high chemical versatility, making it an exciting candidate for wide range biomedical applications. Moreover, based on PDA its derivatives have near-infrared (NIR) absorption, excellent biocompatibility, antioxidative activity, antibacterial cell affinity. can regulate behavior by controlling signal transduction pathways. It governs focal cells at interface. These features make melanin-like fascinating biomaterial regeneration. This paper overviews PDA-based biomaterials' synthesis, properties, interactions with biological entities. Furthermore, utilization nano- microstructures as constituent wound-dressing formulations highlighted.

Опубликована: Май 17, 2022

The aim of this review is to bring together the main natural polymer applications for environmental remediation, as a class nexus materials with advanced properties that offer opportunity integration in single or simultaneous decontamination processes. By identifying polymers derived from agro-industrial sources monomers converted by biotechnology into sustainable polymers, paper offers performances identified literature for: (i) treatment water contaminated heavy metals and emerging pollutants such dyes organics, (ii) remediation soils, (iii) reduction number suspended solids particulate matter (PM) type atmosphere. Because nanotechnology new horizons science, nanocomposite tunable are also studied presented promising context developing integrated products society ensure quality life. As future smart materials, their nanocomposites obtained renewable resources, which inexpensive high surface area, porosity, adsorption due various functional groups. information gathered based on publications field last two decades. perspectives these fascinating should take account scale-up, toxicity nanoparticles, competition food production, well regulations.
