“…Due to these specific properties, bandage materials, transdermal patches, tablet binder, disintegrated vehicle for peptide and gene delivery can be obtained based on nanoscale cellulose, and raw materials for their production are almost unlimited [16][17][18] . In particular, nanocrystalline cellulose has been used as a matrixformer material for long-lasting sustained drug delivery and for food packing materials [19][20][21][22] .…”

“…As such, this sustainable material is advantageous for a broad range of applications, such as Pickering emulsifier [21][22][23] , catalyst and drug carrier 24,25 as well as potential nanofiller for industrial reinforced composites 26,27 . Thus, CNC represents an interesting class of nanomaterials that could be used to fabricate antimicrobial agents due to their bioavailability, biorenewability, biocompatibility and biodegradability.…”

This paper reports on a simple and green approach to fabricate cellulose nanocrystal@polyrhodanine (CNC@PR) core-sheath nanoparticles. Polymerization of rhodanine on the surface of negatively-charged CNC was achieved using ferric chloride as the initiator and oxidant. The coating conditions were optimized by varying the ratio of CNC and monomer as well as the concentration of oxidant. Antimicrobial tests were performed using Escherichia coli (Gram negative) and Bacillus subtilis (Gram positive) as model bacteria and the minimum inhibitory concentrations were determined by plate colony counting methods.Rod-like CNC@PR nanoparticles exhibited promising antimicrobial properties, comparable to spherical nano-composite particles. This may be attributed to the lower percolation threshold for rod-like nanoparticles resulting from the higher aspect ratio. By taking advantage of the nano-size effects, the core-sheath materials can be a potential candidate for antimicrobial applications, such as food-packaging, antimicrobial additives and antimicrobial surfaces or coatings.

Cellulose is a linear polysaccharide and one of the world's most abundant biopolymers. It is one of the renewable biopolymers being studied to reduce the dependence on non-renewable mineral oil based products. Cellulose can be used in different kinds of composites, including the recent nanocomposites.The production of nanoscale cellulose fibers and their use in polymer composites gained increasing attention due to their interesting properties and potential applications. This review paper is trying to cover studies done to use various forms of cellulose as reinforcement for different polymers, as matrix, as reinforcement and matrix for the same nanocomposite and as a component in polyblend nanocomposites beside other polymers.
