Polysaccharide-based nanocomposites and their applications

Abstract

Polysaccharide nanocomposites have become increasingly important materials over the past decade. Polysaccharides offer a green alternative to synthetic polymers in the preparation of soft nanomaterials. They have also been used in composites with hard nanomaterials, such as metal nanoparticles and carbon-based nanomaterials. This mini review describes methods for polysaccharide nanocomposite preparation and reviews the various types and diverse applications for these novel materials.

Surface modification of a polyethylene film for anticoagulant and antimicrobial catheter

“…Nanomaterials have been exploited fro their anti-bacterial applications in biomedical [24–29, 32] and in food packaging applications [41]. Anti-bacterial assessment was carried out with two different bacterial species, B. cereus 3551 (Gram +) and E. coli BL21.…”

“…A single nanocomposite [32], showing a combination of anticoagulant and anti-bacterial properties, has been previously explored by our laboratory [33, 34]. The current study examines the assembly of a covalently attached nanocomposite with hydrophilic coating on the surface of PE films, which exhibits both anticoagulant and anti-bacterial activities.…”

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

“…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. BC also acts as a promising template in the synthesis of a great variety of nanostructures with desired properties and functionalities [7]; thus, ZnO nanoparticles [17], hydroxyapatite [18] and glass [19] scaffolds or composites [20] were obtained.…”

Preparation and characteristics of nanosilver composite based on chitosan-graft-acrylic acid copolymer

“…Recently, CS has been proposed as valuable material for nanotechnology and biotechnology. Some of the new review papers discussed the preparation process of CS-based nanocomposites or hybrid materials with biological activity, for example, by introducing silver nanoparticles (AgNPs) to the matrix of this polysaccharide [8][9][10][11]. AgNPs are known antibacterial and antifungicidal agents and their implementation of different polymers is often reported in the literatures [12][13][14].…”
