Bacterial cellulose in the field of wound healing and regenerative medicine of skin: recent trends and future prospectives

“…The shape of bacterial cellulose may ease the incorporation of nanoparticles of metals [88]. Few studies were done to determine such possibility like impregnation the bacterial cellulose with silver nanoparticles by triethanolamine (TEA) [89]; NaBH4 and UV radiation [64]; moreover by application of hydrazine, hydroxyl amine or ascorbic acid [90] as well as by self-polymerized polydopamine [91] and TEMPO-mediated oxidized BC followed by thermal reduction [88]. However, anchor metallic ions on cellulose fibers generated through these methods are weak [90].…”

Biodegradation of silver functionalised cellulose fibres

“…On the other hand, Gorenšek and Recelj (2007) determined that application to cotton fibres of silver nanopowder with a particle size of 80 nm, in combination with the reactive dyes by the exhaust dyeing procedure, caused 98% bacterial reduction of the bacteria Streptococcus feacalis and Staphylococcus aureus, if the concentration of Ag on the fibres was high enough, which proved its excellent antibacterial activity. As can be seen from the literature, most contemporary research work in the field of antimicrobial finishing of cellulose fibres has focused on the application of colloid silver (de Santa Maria et al, 2009;Ilić et al, 2009;Maneerung et al, 2008;Petica, Gavriliu, Lungu, Buruntea, & Panzaru, 2008;Tankhiwale & Bajpai, 2009;Tien, Tseng, Liao, & Tsung, 2009). This research work includes a study of the influence of the mode of production of the Ag nanoparticles, which directly influences the diameter of the nanoparticles, on their biocidal activity, as well as the washing resistance of the finish when present on the fibres.…”
