“…In the spectrum of unmodified chitosan, the characteristic absorption bands at 3355, 3289 cm −1 (attributed to O–H and N–H stretching vibrations), 2869 cm −1 (CH stretching), 1651cm −1 (C=O stretching of amide I), 1550 cm −1 (N–H bending of amide II), 1151 cm −1 (C–O–C stretching), and 1062, 1027 cm −1 (C–O stretching) were observed ( Figure 4 a). The obtained spectrum is consistent with the literature data [ 55 , 56 ].…”

“…Various compounds such as metals [ 6 , 7 , 8 ] and metal oxides [ 9 , 10 ] in the form of the nanoparticles, antibiotics [ 11 , 12 , 13 ] or natural oil [ 14 ] can be used to modify chitosan for this purpose. A very effective modification consists in converting the amino groups of chitosan into quaternary salts of chitosan [ 15 , 16 , 17 , 18 , 19 , 20 ]. Such chitosan salts are characterized by the highly effective elimination of the various types of the microorganisms.…”

“…Others interesting biocidal agents are N -halamines, the halogen derivatives of the nitrogen (or ammonia), which are also used to modify chitosan. N -Halamines have been the subject of the intensive research in recent two decades [ 15 , 21 , 22 , 23 , 24 , 25 ]. These compounds can significantly differ their chemical structure—they may be aliphatic, aromatic, may contain Cl, Br or I and various other substituents, which affects both physical and chemical properties as well as their biologic activity and durability [ 24 ].…”

“…Notably, this hemostasis foam could stop bleeding quickly without additionally external pressure. Yin et al (2020) synthesized a nanofibrous polyvinyl alcohol (PVA)/quaternary ammonium N-halamine chitosan (CSENDMH) membrane for the hemostasis dressing. This membrane with a bead-free network and porous structure exhibited a good water absorption and excellent blood clotting abilities for the effective hemostatic applications (Yin et al, 2020).…”

This membrane with a bead-free network and porous structure exhibited a good water absorption and excellent blood clotting abilities for the effective hemostatic applications (Yin et al, 2020). Zhang et al (2020) designed a composite sponge of hydroxybutyl chitosan (HBC) and diatom-biosilica (DB) to improve the hemostatic effects (Figure 7).…”
