High lignin-containing nanocelluloses prepared via TEMPO-mediated oxidation and polyethylenimine functionalization for antioxidant and antibacterial applications

Abstract

High lignin-containing Nanocelluloses prepared via TEMPO-mediated oxidation and functionalized by polyethylenimine (PEI) into antioxidant and antibacterial nanocomposites.

Lignin–cellulose complexes derived from agricultural wastes for combined antibacterial and tissue engineering scaffolds for cutaneous leishmaniasis wounds

“…[27][28][29][30] For example, lignin-nanocellulose complexes (LNCs) were found to possess more beneficial characteristics compared to nanocelluloses (NCs) for the development of 3D hydrogel networks with enhanced antibacterial properties, suitable for biomedical applications and antimicrobial coatings. 31,32 This study aims to valorise lignins extracted from agricultural wastes such as SCB and hemp shives through their conversion into 3D TE scaffolds. The biopolymer was extracted and characterised using a range of spectroscopic techniques, followed by biological activity screening to determine the best candidate for further testing.…”

Preparation and characterization of cellulose nanocrystals from corncob via ionic liquid [Bmim][HSO4] hydrolysis: effects of major process conditions on dimensions of the product

“…1 NC can be applied in several elds, such as nanocomposite materials, biomedical products, catalytic supports, electroactive polymers, continuous bres and textiles, food coatings, barriers, separation membranes, biosorbent for water treatment, reinforcements in food packaging, etc. 1,[6][7][8][9][10] Nanocellulose can be produced from inexpensive agricultural residues such as palm and banana rachis, cotton seeds, sugar cane, corncob, rice straw, wheat straw, bamboo cane, and ax bast. 11,12 Usually, the feedstocks are rst pre-treated to remove hemicelluloses and lignin.…”
