Reactive oxygen species scavenging nanofibers with chitosan-stabilized Prussian blue nanoparticles for enhanced wound healing efficacy

Fabrication of Bio-Based Film Comprising Metal Oxide Nanoparticles Loaded Chitosan for Wound Dressing Applications

“…For pure CS, the bands at 658, 894, and 994 cm −1 might refer to N–H bonds, the glucosidic C–O–C stretching vibration, and C–O–C symmetrical stretching, as shown in Table 1 [ 22 , 23 , 24 ]. The recorded bands at 1091, 1152, and 1334 cm −1 may represent the C–O stretching vibration and –OH group of the primary alcoholic group [ 12 , 22 , 25 ]. In addition, the determined bands at 1407, 1538, and 1555 cm −1 exhibit the –OH group of the primary alcoholic group, the symmetric bending of -NH +3 , and amide II (N–H deformation present in the amino group) [ 22 , 23 , 26 ].…”

“…Vanadium oxide (V 2 O 5 ) is considered a transition metal oxide [ 11 ]. It is suitable for several applications, electrical and biological, due to its low toxicity, antimicrobial properties, and biocompatible behavior [ 12 ]. Graphene oxide (GO) has common usage in the nanotechnology field and other studies due to its two-dimensional honeycomb structure [ 13 , 14 ].…”

Progress in the preparation of Prussian blue-based nanomaterials for biomedical applications

“…Choi et al prepared PB-electrospinning nanofibers in another way, using the ROS scavenging power of PBNPs to demonstrate its good antioxidant and wound-healing properties. 135 In the study, chitosan of different molecular weights was used as dispersants to prepare PBNPs with a particle size distribution below 100 nm, and then their aqueous solutions were uniformly mixed with 10 wt% PVA aqueous solutions for electrospinning (Fig. 10H).…”
