“…Biomass lignin, an aromatic polymer containing a structural unit of oxyphenylpropanol or its derivatives, is the second most abundant natural macromolecular organic material in the world . It has a high carbon content and abundant chemical energy and is widely present in gymnosperms, angiosperms, and all vascular plants, whereas industrial biomass lignin mainly includes lignosulfonate, sulfate lignin, and alkali lignin . As an alternative precursor, lignin has been converted to high‐valuable nanoscale fluorescent materials in previous work .…”

Sustainable, inexpensive, and environmentally friendly biomass waste can be exploited for large‐scale production of carbon nanomaterials. Here, alkali lignin was employed as a precursor to synthesize carbon quantum dots (CQDs) with bright green fluorescence through a simple one‐pot route. The prepared CQDs had a size of 1.5–3.5 nm, were water‐dispersible, and showed wonderful biocompatibility, in addition to their excellent photoluminescence and electrocatalysis properties. These high‐quality CQDs could be used in a wide range of applications such as metal‐ion detection, cell imaging, and electrocatalysis. The wide range of biomass lignin feedstocks provide a green, low‐cost, and viable strategy for producing high‐quality fluorescent CQDs and enable the conversion of biomass waste into high‐value products that promote sustainable development of the economy and human society.

“…A new hydrogel was prepared as an ointment for anti-infection, which had abilities to prevent infection of burn wound and could be used as an anti-inflammatory dressing and aid-healing material [453]. Lignin/CS hydrogels show a good potential applicability in wound healing, since these hydrogels present a good cell attachment and proliferation of NIH 3T3 mouse fibroblast [454]. Highly antibacterial lignin-based hydrogels for drug delivery have been recently reported against Staphylococcus aureus and Proteus mirabilis, behaviour demonstrated for hydrogels prepared with lignin, cellulose, hyaluronan, Gantrez S-97 (poly(methyl vinyl ether-co-maleic acid), poly(ethylene glycol) or glycerol and others [455][456][457].…”

New trends in biomedical applications of the hybrid polymeric hydrogels, obtained by combining natural polymers with synthetic ones, have been reviewed. Homopolysaccharides, heteropolysaccharides, as well as polypeptides, proteins and nucleic acids, are presented from the point of view of their ability to form hydrogels with synthetic polymers, the preparation procedures for polymeric organic hybrid hydrogels, general physico-chemical properties and main biomedical applications (i.e., tissue engineering, wound dressing, drug delivery, etc.).

“…Так, при сполученні з ізолятом соєвого протеїну полімерна плівка набуває антимікробної властивості проти деяких мікроскопічних грибів (F. oxysporum, P. expansum D) [30]. Антимікробні властивості також відзначалися в сумішей хітозану з лігніном [31,32]. Окрім антимікробних властивостей, матеріал має достатню пластичність і здатність швидше загоювати рани, тому є перспективним для подальшого використання як пластиру.…”

“…У дослідженні [32] відзначалоcь, що наявність лігніну в полімерних сумішах із синтетичними полімерами (з поліпропіленом та з поліетиленом низької щільності) спричиняло часткове руйнування фрагментів поліолефінів за допомогою гідролітичних ферментів P. chysosporium [35].…”

acid, polybutylene succinate, polyhydroxybutyrate, etc.). The purpose of modern research is to search and create bioplastics that have similar properties to traditional plastic and are characterized by the main featurethe ability to biodegradation. Objective. Analysis of the properties of biopolymers, which include lignin, depending on the methods of its obtaining, polymers structure, and lignin content. Conclusions. Among the types of lignin considered, alkaline lignin, which has a structure similar to natural lignin, is the most promising for further research and is better suited to natural polymers that are capable of biodegradation (polylactic acid, cellulose, polyhydroxybutyrate, etc.). The addition of lignin to biopolymers slows down the process of decomposition, and when interacting with syn thetic polymers, it gives them the property of minor biodegradation. The best ability to combine with lignin is made up of polymers containing a large number of polar groups, among biopolymerspolyesters polyhydroxybutyrate and polyethylene terephthalate. When using lignin in polymer mixtures, the mechanical properties improve (provided that the lignin is completely mixed with the polymer matrix), the plastics stabilize, and the combustion rate decreases. Among all the considered mixtures of natural polymers and lignin, the best mechanical properties were observed for the mixture of lignin and cellulose.
