Hydrothermal synthesis of bacterial cellulose/AgNPs composite: A “green” route for antibacterial application

Preparation and Characterization of Bacterial Cellulose Composites with Silver Nanoparticles

“…For BC composites with silver nanoparticles a hydrothermal method was used, without the utilization of any catalysts, using the discs of BC layer as a reducing and stabilizing agent (Yang et al, 2012). Cleaned wet BC films were cut into discs with an average diameter of 10 mm, then were placed in a flask with 0.001 Aeolus quadrupole mass spectrometer for analysis of gases, and evolved by the heating specimens.…”

“…Bacterial cellulose itself does not possess antimicrobial activity. However, taking into account its favorable structure, it is possible to use it in a composition with "incrusting the surface" heavy metal nanoparticles, wherein they will act as a local agent for directed kill of bacteria, thereby possessing conditions for faster wound healing (Czaja et al, 2004;Yang et al, 2012).…”

Synthesis, Chemistry, and Medical Application of Bacterial Cellulose Nanocomposites

“…The composites showed better thermal properties and flexibility compared to pure BC [109]. Yang et al synthesized BC-Ag nanocomposites using this strategy, showing that the incorporated Ag nanoparticles enhanced the bactericidal properties of BC [110]. Ul-Islam et al prepared BC composites with montmorillonite (MMT) clay with the same approach, mixing well-dispersed MMT particles into the BC fibril network.…”

Recent Advances on the Development of Antibacterial Polysaccharide-Based Materials

“…Antibacterial cellulose-based materials are obtained primarily by the simple combination of cellulose (or cellulose derivatives) with distinct biocides (including metal and metal oxide nanoparticles and salts, Antibacterial Cellulose/Metal (Metal Oxide) Nanoparticle Composites In the last decade, the combination of different forms of cellulose, like plant fibers (Csóka et al 2012;Raghavendra et al 2013;Simonc et al 2008;Teli and Sheikh. 2012;Wang et al 2011Wang et al , 2013bZhu et al 2009), cotton fabrics Park et al 2012), filter paper (Imani et al 2011;Tang et al 2009; Tankhiwale and Bajpai 2009), microcrystalline cellulose (Dong et al 2014;Huang et al 2013;Jankauskaitė et al 2014;Li et al 2011Li et al , 2012a, bacterial cellulose (Barud et al 2011;Dobre and Stoica-Guzun 2013;Jung et al 2009;Liu et al 2012a;Maneerung et al 2008;Maria et al 2010;Sureshkumar et al 2010;Wu et al 2014b;Yang et al 2012aYang et al , b, 2013Zhang et al 2013), nanofibrillated cellulose (Díez et al 2011;Martins et al 2012;Xiong et al 2013), as well as cellulose derivatives (e.g., cellulose acetate (Hyuk Jang et al 2014;Perera et al 2014;Scheeren et al 2011;Son et al 2006), hydroxypropyl cellulose (Angelova et al 2012), and cellulose acetate phthalate (Necula et al 2010)), with silver nanoparticles (Ag NPs), following diverse methods, is definitely the most extensively studied strategy for the design of ant...…”

“…The obtained BC-Ag nanocomposite membranes own superparamagnetic properties and antibacterial action against both E. coli and B. subtilis bacteria and were found to be effective on the sterilization of fermentation culture mediua. More recently, Yang et al (2012a) described a hydrothermal synthesis of a BC-Ag NP composite using BC as both reducing and stabilizing agent. Under optimum conditions, small-size Ag NPs (17.1 + À5 nm) were formed on the BC matrix, with an Ag content of 1.78 % (%w/w) and an MIC (S. aureus) value of 1.30 Â 10 À4 mug/CFU.…”
