“…For instance, the natural polymers with biocompatible nature obtained from polysaccharides and polypeptides as artificial scaffolds were helpful in tissue repairs Tian et al, 2015). In this regard, researchers have explored cellulose in various applications such as wound dressing (Haider et al, 2018), vascular tissue reconstruction (Bäckdahl et al, 2006), microbial growth suppression (de Faria et al, 2017) and filter aids (Jain et al, 2018). Therefore, aplethora of works has been investigated for exploring the potential role of cellulose in diverse type of applications (Konwarh, Karak, & Misra, 2013;Sheikh et al, 2015;Adepu et al, 2017).…”

In the present work, a novel strategy was explored to fabricate nanofiber scaffolds consisting of cellulose assimilated with titanium dioxide (TiO 2 ) and silver (Ag) nanoparticles (NPs). The concentration of the TiO 2 NPs in the composite was adjusted to 1.0, 1.5, and 2.0 wt % with respect to polymer concentration used for the electrospinning of colloidal solutions. The fabricated composite scaffolds were dispensed to alkaline deacetylation using 0.05 M NaOH to remove the acetyl groups in order to generate pure cellulose nanofibers containing TiO 2 NPs. Moreover, to augment our nanofiber scaffolds with antibacterial activity, the in situ deposition approach of using Ag NPs was utilized with varied molar concentrations of 0.14, 0.42, and 0.71 M. The physicochemical properties of the nanofibers were identified by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) and contact angle meter studies. This demonstrated the presence of both TiO 2 and Ag NPs and complete deacetylation of nanofibers. The antibacterial efficiency of the nanofibers was scrutinized against Escherichia coli and Staphylococcus aureus, revealing proper in situ deposition of Ag NPs andconfirming the nanofibers are antibacterial in nature. The biocompatibility of the scaffolds was accustomed using chicken embryo fibroblasts, which confirmed their potential role to be used as wound-healing materials. Furthermore, the fabricated scaffolds were subjected to analysis in simulated body fluid at 37 C to induce mineralization for future osseous tissue integration. These results indicate that fabricated composite nanofiber scaffolds with multifunctional characteristics will have a highest potential as a future candidate for promoting new tissues artificially.

Silver Nanoparticles for Water Pollution Monitoring and Treatments: Ecosafety Challenge and Cellulose-Based Hybrids Solution

et al. 2020

View full text Add to dashboard Cite

Silver nanoparticles (AgNPs) are widely used as engineered nanomaterials (ENMs) in many advanced nanotechnologies, due to their versatile, easy and cheap preparations combined with peculiar chemical-physical properties. Their increased production and integration in environmental applications including water treatment raise concerns for their impact on humans and the environment. An eco-design strategy that makes it possible to combine the best material performances with no risk for the natural ecosystems and living beings has been recently proposed. This review envisages potential hybrid solutions of AgNPs for water pollution monitoring and remediation to satisfy their successful, environmentally safe (ecosafe) application. Being extremely efficient in pollutants sensing and degradation, their ecosafe application can be achieved in combination with polymeric-based materials, especially with cellulose, by following an eco-design approach. In fact, (AgNPs)–cellulose hybrids have the double advantage of being easily produced using recycled material, with low costs and possible reuse, and of being ecosafe, if properly designed. An updated view of the use and prospects of these advanced hybrids AgNP-based materials is provided, which will surely speed their environmental application with consequent significant economic and environmental impact.

“…Filtration is a widely used method of treating water and recent, numerous attempts aim to develop effective antibacterial composite-based filtration materials [5,6]. Promising examples with respect to their potential application include synthetic polymers (e.g., polypropylene, polyurethane, polyacrylonitrile) [7][8][9], natural materials (e.g., chitin, chitosan, cellulose, collagen) [10][11][12] as well as carbon-based composites [13,14], which have been covered with silver nanoparticles (AgNPs) using diverse techniques. The use of silver compounds to disinfect water and the procedure's resulting death of fungi, molds, bacteria and various spores has been documented since ancient times, as cited by Atiyeh [15].…”

Functionalization of 3D Chitinous Skeletal Scaffolds of Sponge Origin Using Silver Nanoparticles and Their Antibacterial Properties

et al. 2020

View full text Add to dashboard Cite

Chitin, as one of nature’s most abundant structural polysaccharides, possesses worldwide, high industrial potential and a functionality that is topically pertinent. Nowadays, the metallization of naturally predesigned, 3D chitinous scaffolds originating from marine sponges is drawing focused attention. These invertebrates represent a unique, renewable source of specialized chitin due to their ability to grow under marine farming conditions. In this study, the development of composite material in the form of 3D chitin-based skeletal scaffolds covered with silver nanoparticles (AgNPs) and Ag-bromide is described for the first time. Additionally, the antibacterial properties of the obtained materials and their possible applications as a water filtration system are also investigated.
