Nanocellulose, as a promising natural material, has recently received much attention because of its remarkable features including recyclability, biocompatibility, low risk of toxicity, and tunable surface properties. This review article first introduces three types of nanocellulose (nanocrystalline, nanofibrillar, and bacterial) and evaluates their production processes. In addition, contemporary research is discussed in the formulations of nanoparticles, tablets, hydrogels, and aerogels. As reported in the literature, the release time of nanocellulose-based systems varies from a few minutes to several days as they provide a controlled and sustained release. Thus, such systems have shown considerable potential for developing a novel generation of controlled drug delivery for different routes of administration (oral, transdermal, etc.). This review facilitates the selection of proper source and processing techniques for nanocellulose production while addressing opportunities and challenges ahead ending up with identifying sustainable ongoing research directions into its applications in drug delivery.

“…Therefore, the wettability and dye ability of the fabrics are improved after plasma treatment (Kan and Man, 2018). However, if impregnate the plasma-treated fabrics in a CNPs solution instantly, the radicals react with the functional groups of CNPs (−OH and/or −NH 2 ) via coating and the CNPs are grafted on the surface of the fabrics permanently (Vrabič Brodnjak et al , 2018).…”

Purpose This paper aims at studying the oxygen plasma treatment and the previously prepared and fully characterized chitosan nanoparticles (CNPs) as a green and eco-friendly strategy for surface modification of viscose fabric. This was done to render viscose fabric dye able with two types of acid dyes that do not have direct affinity to fix on it via improving the fabric wettability. Design/methodology/approach To achieve the goal, viscose fabric was activated with oxygen plasma at optimum conditions and coated with different concentrations of CNPs solution via conventional pad dry cure technique. The untreated and plasma-treated fabrics with CNPs were dyed with two types of acid dyes, namely, Acid Orange 7 and Methyl Red under determined conditions. The color strength (K/S), fastness properties to light, rubbing and perspiration, add on %, tensile strength, wettability and durability of the dyed samples were determined and compared. Findings The results divulged that oxygen plasma-treated fabric with CNPs and the aforementioned dyes in question could improve the flowing properties in comparison with untreated fabric: (a) the fabric wettability expressed as wetting area mm2; (b) the dye ability and fastness properties of viscose fabrics expressed as K/S and fastness properties; and (c) the strength properties and add on % of the treated fabric. On the other hand, the durability of the plasma-treated fabric decreased with increasing washing cycles. Originality/value The novelty addressed here was using plasma treatment as an eco-friendly pre-treatment approach for attachment of CNPs as a multifunctional green bio-nano polymer onto viscose fabric, which improved the dyeing properties of the fabric with acid dyes that do not have direct affinity to fix onto it.

“…Therefore, the wettability and dyeability of the fibers are improved after plasma treatment. However, if impregnate the plasma-treated fibers in a chitosan solution immediately, the radicals react with the functional groups of chitosan (−OH and NH 2 ), and chitosan is grafted on the surface of the fibers permanently (Vrabič Brodnjak et al , 2018; Haji et al , 2016b). The presence of amine groups in the structure of the grafted chitosan increases the affinity of the fiber for anionic dyes in acidic dyebath (Haji et al , 2016b).…”

Purpose The dyeing of cellulosic and proteinous fibers with natural and synthetic colorants usually needs large amounts of metal salts to promote the dyeing procedure. To get rid of the necessity to use metal salts, plasma treatment and subsequent attachment of chitosan biopolymer were considered as green processes for surface functionalization of wool and cotton. The purpose of this paper is to investigate the effect of oxygen plasma treatment and attachment of chitosan on the dyeability of wool and cotton fabrics using walnut and weld as model natural dyes, as well as C.I. reactive blue 50 and C.I. acid blue 92 as model synthetic dyes. Design/methodology/approach Wool and cotton fabrics were modified with oxygen plasma and coated with chitosan solution. The un-modified and modified samples were dyed with the above-mentioned dyes under constant conditions. The color strength, color coordinates and fastness properties of the dyed samples were determined and compared. Findings The results showed that oxygen plasma treatment could improve the dyeability and fastness properties of wool and cotton fibers when dyed with all of the above-mentioned dyes. Attachment of chitosan to the plasma-treated samples significantly improved the dyeability of wool and cotton fibers with walnut, acid and reactive dyes. The fastness properties of the dyed samples were enhanced by plasma treatment and chitosan coating. Originality/value This study uses plasma treatment as an environmentally friendly pre-treatment for attachment of chitosan on wool and cotton. This process improved the dyeing properties of both fibers. The use of metal salts in not needed for dyeing of wool and cotton according to the investigated process.
