pH-responsive release behavior and anti-bacterial activity of bacterial cellulose-silver nanocomposites

Bacterial cellulose as a material for wound treatment: Properties and modifications. A review

“…Attempts to improve the antimicrobial efficiency of BCbased dressings have involved the impregnation of numerous organic and polymeric substances as well as inorganic materials bearing antimicrobial activity into the BC matrix. The topical antiseptics utilized for BC modifications have included biological and synthetic polymers with antimicrobial activity (Figueiredo et al, 2015;Jiang et al, 2014), antimicrobial peptides (Basmaji et al, 2014), cationic antiseptics (e.g., quaternary ammonium compounds and biguanides) (Kukharenko et al, 2014;Serafica et al, 2010), antibiotics (Lacin, 2014), and inorganic compounds (e.g., metal or graphene nanoparticles and metal oxides) (Shao et al, 2015a(Shao et al, 2015bUl-Islam et al, 2014). The general principle of bacterial inactivation by different antimicrobial active substances is similar -the disruption of the bacterial cytoplasmic membrane.…”

Fabrication of 3D calcium phosphates based scaffolds using bacterial cellulose as template

“…Moreover, BC represents a component of many composite materials with different technological applications [4,6,8,9]; some examples are given further: BC/silver [10], BC/graphite [11], BC/chitosan [12], BC/poly(vinyl alcohol) [13], BC/SiO 2 [14], BC/cement [15] etc. Usually, starting from a 3D porous network of BC and following an in situ preparation approach or an impregnation procedure [16], composites with improved or completely new properties can be fabricated.…”

Application of Taguchi method in the optimization of synthesis of cellulose-MgO bionanocomposite as antibacterial agent

“…Bacterial Polish Journal of Chemical Technology, 21, 4, 116-122, 10.2478/pjct-2019-0047 cellulose is mainly produced by bacteria of the genus Gluconacetobacter that are nonpathogenic bacteria, among which, Gluconacetobacter xylinum produces the greatest amount of cellulose 21, 22 . The use of polymerbased nanocomposites containing metal nanoparticles has several advantages over metal nanoparticles, including trapping of nanoparticles within the polymer matrix to prevent their accumulation, better surface distribution of nanoparticles, greater contact of nanoparticles with the bacteria and faster removal of bacteria 23 . Previous studies have shown that the ratio of nanoparticles to the biopolymer as well as their stirring time are among the factors affecting the antimicrobial activity of nanocomposites 18, 24 .…”
