Antibacterial lignin-based nanoparticles and their use in composite materials

Nanoscale Advances, Год журнала: 2022, Номер 4(21), С. 4447 - 4469

Lignin, one of the most abundant biopolymers on earth, has been traditionally considered a low-value by-product pulp and paper industries. This renewable raw material, besides being source valuable molecules for chemical industry, also antioxidant, UV-absorbing, antibacterial properties in its macromolecular form. Moreover, lignin form nanoparticles (LigNPs) presents advantages over bulk lignin, such as higher reactivity due to larger surface-to-volume ratio. In view rapid surge antimicrobial resistance (AMR), caused by overuse antibiotics, continuous development novel agents is needed. The use LigNPs suitable alternative conventional antibiotics topical application or disinfectants surfaces packaging. Besides, their multiple unspecific targets bacterial cell may prevent emergence AMR. review summarizes latest developments nano-formulated both dispersion embedded materials. following roles formulation NPs have analyzed: (i) an active nanoformulations, (ii) reducing capping agent metals, (iii) carrier other agents. Finally, covers inclusion films, fibers, hydrogels, foams, obtaining lignin-based nanocomposites variety applications, including food packaging, wound healing, medical coatings.

Lignins as Promising Renewable Biopolymers and Bioactive Compounds for High-Performance Materials

Polymers, Год журнала: 2023, Номер 15(15), С. 3177 - 3177

Опубликована: Июль 26, 2023

The recycling of biomass into high-value-added materials requires important developments in research and technology to create a sustainable circular economy. Lignin, as component biomass, is multipurpose aromatic polymer with significant potential be used renewable bioresource many fields which it acts both promising biopolymer bioactive compound. This comprehensive review gives brief insights the recent technological trends on lignin development utilization. It divided ten main sections, starting an outlook its diversity; properties possibilities raw material for fuels, chemicals, plastics, or thermoset substitutes; new use compound nanoparticles, hydrogels, 3D-printing-based biomaterials, energy production storage. In each section are presented preparation lignin-based especially green approaches obtaining multifunctional blends bio(nano)composites; most suitable type category envisaged products; obtained materials, etc. Different application categories within various sectors, could provide completely conversion, such agriculture environment protection, food packaging, biomedicine, cosmetics, also described. medical therapeutic lignin-derived evidenced applications antimicrobial, antiviral, antitumor agents; carriers drug delivery systems controlled/targeting release; tissue engineering wound healing; coatings, natural sunscreen, surfactants. Lignin mainly fuel, and, recently, studies highlighted more bioenergy technologies, supercapacitor electrode, photocatalysts, photovoltaics.

Methods to Determine Chain-Breaking Antioxidant Activity of Nanomaterials beyond DPPH•. A Review

Antioxidants, Год журнала: 2021, Номер 10(10), С. 1551 - 1551

Опубликована: Сен. 29, 2021

This review highlights the progress made in recent years understanding mechanism of action nanomaterials with antioxidant activity and chemical methods used to evaluate their activity. Nanomaterials represent one most frontiers research for improved antioxidants, but further development is hampered by a poor characterization ‘‘antioxidant activity’’ property using oversimplified methods. Inhibited autoxidation experiments provide valuable information about interaction important radicals involved lipid oxidation, namely alkylperoxyl hydroperoxyl radicals, demonstrate unambiguously ability stop oxidation organic materials. It proposed that should always complement (and possibly replace) use assays based on quenching stable (such as DPPH• ABTS•+). The mechanisms leading inhibition (sacrificial catalytic radical trapping activity) are described context nanoantioxidants. Guidelines selection appropriate testing conditions meaningful kinetic analysis also given.

From sugarcane to skin: Lignin as a multifunctional ingredient for cosmetic application

International Journal of Biological Macromolecules, Год журнала: 2023, Номер 234, С. 123592 - 123592

Опубликована: Фев. 10, 2023

Lignin has been suggested as a promising candidate for cosmetic applications due to its remarkable potential absorb ultraviolet rays and distinctive antioxidant activity. This study aims at evaluating the performance of lignin from sugarcane bagasse (SCB) natural UV blocker, antioxidant, pigment. was extracted SCB, characterized incorporated into blemish balm (BB) cream. The biological potential, concretely, in vitro vivo sun protection factor (SPF) UVA-PF, safety were assessed. A high-purity SCB (>92 %) obtained by mild alkaline extraction process. results cytotoxicity, mutagenicity, skin sensitization acute cutaneous irritation demonstrated that is safe topical applications. showed capacity scavenge both ABTS DPPH radicals, which preserved after incorporation formulation. Notable achieved terms SPF 9.5 ± 2.9 9.6 0.8, respectively. Furthermore, tested lignin-based BB cream revealed broad-spectrum (critical wavelength 378 0.5 nm). These suggest multifunctional ingredient use products.
