Green Synthesis and Incorporation of Sericin Silver Nanoclusters into Electrospun Ultrafine Cellulose Acetate Fibers for Anti-Bacterial Applications

Abstract

Fiber based antibacterial materials have gained an enormous attraction for the researchers in these days. In this study, a novel Sericin Encapsulated Silver Nanoclusters (sericin-AgNCs) were synthesized through single pot and green synthesis route. Subsequently these sericin-AgNCs were incorporated into ultrafine electrospun cellulose acetate (CA) fibers for assessing the antibacterial performance. The physicochemical properties of sericin-AgNCs/CA composite fibers were investigated by transmission electron microscopy (TEM), field emission electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR) and wide X-ray diffraction (XRD). The antibacterial properties of sericin-AgNCs/CA composite fibers against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were systematically evaluated. The results showed that sericin-AgNCs incorporated in ultrafine CA fibers have played a vital role for antibacterial activity. An amount of 0.17 mg/mL sericin-AgNCs to CA fibers showed more than 90% results and elevated upto >99.9% with 1.7 mg/mL of sericin-AgNCs against E. coli. The study indicated that sericin-AgNCs/CA composite confirms an enhanced antibacterial efficiency, which could be used as a promising antibacterial product.

Salts and water‐free dyeing of cellulose nanofibers using novel green deep eutectic solvents: Isotherm, kinetics, and thermodynamic studies

“…Cellulose nanofibers (CNF) have been utilized for various applications including energy devices, separation membranes, biomedical, casual apparel, and smart wearables because of their breathability and air permeability 1–5 . Electrospinning technique for the higher production of CNF has become more practical these days and has been used for bulk production of nanofiber‐based functional non‐woven 6,7 . CNF show better properties viz.…”

Antibacterial self-fused supramolecular polymer hydrogel for infected wound healing

“…Therefore, it is necessary to develop materials for wound care, and the common strategy is to treat the wound with a dressing [5][6][7][8][9]. A series of wound dressings have been reported, such as sponges, fibers, microparticles, microneedles, and hydrogels [10][11][12][13][14][15][16][17]. Among these, hydrogels exhibit huge potential because they are permeable and can absorb excess tissue exudates.…”

Introducing Deep Eutectic Solvents as a Water-Free Dyeing Medium for Poly (1,4-cYclohexane Dimethylene Isosorbide Terephthalate) PICT Nanofibers

“…Poly (1,4-cyclohexane dimethylene isosorbide terephthalate) PICT is one of the bio-based polymers and is widely used in different applications because of its ease of production, eco-friendly character, green source of raw material (wheat, sugar, and corn), unique molecular structure, good transition temperature, and mechanical properties [1]. The unique characteristics of nanofibers such as a high surface area and fine diameter have increased their use in a number of applications such as biomedical, surgical, tissue engineering, filtration membranes, wearable conductives, and apparel applications [2][3][4][5][6][7][8].…”

“…For advanced apparel applications, the enhancement of the aesthetic properties of nanofibers is equally important as their functional characteristics [4,5]. Some conventionally dyed nanofibers such as the dyeing of polyester nanofibers with disperse dyes using the batch dyeing method [6], the dyeing of cellulose acetate nanofibers with disperse dyes using the pad-dry and bake-dry method [7], and polyurethane nanofibers dyed using the pad-dry-bake method [8], have been previously reported. However, problems such as lower color strength and lower color fastness remained a challenge.…”
