Benign Production of AgNPs/Bacterial Nanocellulose for Wound Healing Dress: Antioxidant, Cytotoxicity and In Vitro Studies

Eco-Friendly Procedure for Rendering the Antibacterial and Antioxidant of Cotton Fabrics via Phyto-Synthesized AgNPs With Malva sylvestris (MS) Natural Colorant

“…An increase in the percent of antioxidant was observed as the concentration of MS increased up to 50% o.w.f. ( DellaGreca et al, 2009 ; Shaheen et al, 2021 ), and antioxidant amounts of the cotton sample dyed with MS was 30% lower than of the mordanted with TA. However, the un-mordanted samples dyed with MS enhanced the antioxidant activity by more than 30% ( Razavi et al, 2011 ).…”

“…Data indicated that antibacterial efficiency of the dyed samples with MS colorant without any treatment, with TA and AgNPs were 41–44%. The considerable antibacterial activity of MS colorants can be attributed to the presence of anthocyanin, flavonoids, vitamins, terpenoides ( Dulger and Gonuz, 2004 ; El-Rafie et al, 2010 ; Shaheen et al, 2021 ). The antibacterial efficiency of the cotton samples pre-mordanted with TA and dyed with MS colorants was around 80%.…”

“…This shows the intrinsic antibacterial properties of MS colorants and TA with polyphenolic chemical structure and their strong intermolecular interactions with cellulose chains of cotton. In general, it was found that the pre-mordanting with TA should be performed in the presence of metal salts for attaining a durable antibacterial activity on the cotton fabrics ( Shaheen et al, 2021 ).…”

“…with the sequence of a registered strain called Komagataeibacter xylinus NBRC 11664. Shaheen et al [28] found a strain namely, SA3.1, which was isolated from spoilage apple, the biochemical assays of the strain SA3.1 exhibited the identical characteristics of K. hansenii NCIMB 8746, the molecular identification was performed through amplifying of the 16s rDNA fragment (1500 bp) of K. hansenii SA3.1 by using PCR technique. The latter technique affirmed that, undoubtedly, the similarity of the examined strain was much closer to the sequence of Komagataeibacter hansenii NBRC 14,820 which attained 99.4%.…”

Evaluation of Wound Healing Effect of Curcumin Loaded OPL Carbon Nanospheres Embedded Chitosan Membranes

“…Along with several composites, carbon based nanomaterials/Ch membranes and hydrogels have been emerging in recent years due to their acceptable biological environment [23,24]. Single and multi-walled carbon/Ch [25], carbon dots doped with cerium [26], carbon nanotubes and fullerenes [27], nitrogen doped [28] and lanthanum doped carbon quantum dots [29] and many have been explored.…”
