“…Wang et al [ 88 ], have exploited microwave irradiation to assist the incorporation of silver nanoparticles (AgNPs) into quaternized alkali lignin (QAL) to enhance the antibacterial activity of the AgNPs via the electrostatic capture. To prepare the QAL, alkali lignin was dissolved in a sodium hydroxide solution and heated at 85–90 °C in the presence of 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHMAC) for 4 h. The positively charged QAL serves as both a stabilizing and reductive carrier, but also endows the system with electrostatic effects toward negatively charged Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ).…”

“…Increasing the addition of SLS from 10 to 40 wt%, the obtained inhibition zone becomes larger and larger (from 8.0 mm for SLS 10 -CF-M to 11.0 mm for SLS 40 -CF-M), which demonstrates that the presence of SLS is bene cial for inhibiting the growth of testing bacteria. Generally, lignin (from hardwood or softwood) contains abundant phenolic hydroxyl groups, which are effective for inhibiting oxidation and bacteria growth (such as P. aeruginosa, S. enteritidis, E. coli, B. cereus, S. aureus) (Lourencon et al, 2021;Wang et al, 2021). In addition, the special presence of sulfonate group in SLS as compared with other lignin is also an effectively antibacterial factor (Asadullah et al, 2020).…”

“…9 Moreover, the polymer can be utilized as the carrier to adjust the release rate of silver ions and further reduce the biological toxicity induced by the release of free silver nanoparticles or silver ions. 10 However, there are some problems in synthetic polymer-based AgNP composite materials, such as poor biocompatibility, cumbersome and rigorous preparation methods, limiting their further applications. 11 Hence, it is essential to choose green carriers for the facile fabrication of silver nanocomposite antibacterial materials.…”
