“…When compared to the FTIR bands of crayfish and shrimp chitosan-coated cotton fabric (Figs 4c, 4d), changes were observed in the FTIR spectra of chitosan+nano Ag coated fabric samples (Figs 4a, 4b). As mentioned in previous studies, these shifting in the FTIR peaks indicate that the formation of coordination bonds between the amine groups of the chitosan and the nano-Ag particles (Xu et al 2019), or that Ag is chelated by both amino and hydroxyl groups of the chitosan (Chen et al 2014). This shows that nano-Ag is chemically bonded to cotton fabric via shrimp and crayfish chitosan.…”

The finishing process with the antibacterial agents that protect the environment and human health is gaining importance. This study aims 1) to develop new generation antibacterial finishes using chitosan as a binder for nano-Ag coatings, 2) to determine the applicability of chitosan from shrimp and crayfish for textile production and 3) to contribute to environmentally friendly textile production. Chitosan from shrimp and crayfish wastes were used as adhesive in the binding of nanoparticles to fabric surfaces. The bonding properties of the nano-Ag particles on the fabric surfaces were investigated by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and Energy dispersive x-ray spectroscopy (EDX) analysis. The antibacterial effectiveness of fabrics against Escherichia coli ATCC 8739 were tested according to JIS L 1902-2015 standard. The crayfish and shrimp chitosan formed a colorless film and coated the nano-Ag particles homogeneously on the cotton fabric. Antibacterial activity values were calculated as 3.10 and 5.74 for crayfish and shrimp chitosan coated cotton fabrics and as 5.37 and 5.10 for crayfish and shrimp chitosan+nano Ag coated cotton fabrics, respectively. Chitosan nano-Ag coating which exhibited a good antibacterial activity (99.99% reduction) against E. coli ATCC 8739 can be used in the manufacture of garments such as medical textiles, baby clothes, and underwear. The use of chitosan as a binder can reduce the use of chemicals in textile printing and pigment dying in finishing materials, pollutant discharges and emissions from industrial sources. Also, it presents innovative solutions for the protection of human and environmental health. Özet: Çevreyi ve insan sağlığını koruyan antibakteriyel malzemelerle bitim işlemi son yıllarda önem kazanmaktadır. Bu çalışmanın amacı da 1) kitosanı nano-gümüş (Ag) kaplamalar için bağlayıcı olarak kullanarak yeni nesil antibakteriyel apreler geliştirmek, 2) karides ve kerevitlerden üretilen kitosanın tekstil üretimi için uygulanabilirliğini belirlemek ve 3) çevre dostu tekstil üretimine katkıda bulunmaktır. Çalışmada, karides ve kerevit atıklarından üretilen kitosan, Ag nanopartiküllerinin kumaş yüzeylerine bağlanmasında yapışkan olarak kullanılmıştır. Nano-Ag partiküllerinin kitosan aracılığıyla kumaş yüzeylerine bağlanma özellikleri Fourier dönüşümlü kızılötesi spektroskopi (FTIR), Taramalı elektron mikroskobu (SEM) ve Enerji dağılımlı x ışını (EDX) analizleri ile incelenmiştir. Kumaşların Escherichia coli ATCC 8739' ye karşı antibakteriyel aktiviteleri JIS L 1902-2015 standardına göre test edilmiştir. Çalışmanın sonuçları kerevit ve karides kitosanlarının renksiz bir film oluşturduğunu ve Ag nanoparçacıklarını pamuklu kumaş üzerine homojen bir şekilde kapladığını göstermiştir. Kerevit kitosanı ve karides kitosanı ile kaplı pamuklu kumaşların antibakteriyel aktivite değerleri sırasıyla, 3,10 ve 5,74 olarak hesaplanırken, kerevit kitosanı+nano-Ag ve karides kitosanı+nano-Ag ile kaplanmış pamuklu kumaşların antibakteriyel aktivite...

Metal-based nanoparticles with potential antioxidant and antimicrobial properties have led to their incorporation of biomaterials for human health care importance. The present investigation is to study on the silver nanoparticles grafted chitosan (Chi-Ag-NPs) composite materials due to their potential applications. Chi-Ag-NPs were synthesized by chemical reduction of silver nitrate salts and biodegradable chitosan. The obtained Chi-Ag-NPs were characterised for Fouriertransform infrared spectroscopy (FTIR), scanning electron microscope (SEM), Transmission electron microscopy (TEM), X-ray powder diffraction, antioxidant and antibacterial properties. UV-visible spectra showed the configuration proficiency of Ag-NPs and chitosan. FTIR spectra indicated that the functional groups of chitosan have particular interactions with Ag-NPs. Particle size and TEM analyses showed that Chi-Ag-NPs were equivalently dispersed in matrix with an average size of 10-230 nm. The surface morphological structures of chitosan has played important role in influencing the adsorption of Ag-NPs. Chi-Ag-NPs were tested for their bioactive properties and results exhibited higher antioxidant and antibacterial activities by the addition of Ag-NPs. Chi-Ag-NPs composites were non-toxic to L929 fibroblast cells. The present investigation suggested that chitosan will be a good source for the preparation of bionanocomposite materials and also could be useful in different industrial and biomedical applications.

“…The quest for environmental friendly and sustainable methods to synthesize AgNPs has gained momentum during the past decade and shifted the interest of the researchers towards the bio-reduction potential of microorganisms [9]- [12], and plant extracts [13]- [20]. Natural polymers have also been used as reducing and capping agents in the synthesis of nano-particles [21]- [24]. The eco-friendly green synthesis methods suffer from the drawback of longer synthesis period for generation of AgNPs [25].…”

Light driven, photon mediated green synthesis of silver nano-particles (AgNPs) was carried out using aqueous silver nitrate solution (1 mM) and aqueous extract of almond (Prunus amugdalus). Experiments were carried out in dark, diffused sunlight and direct sunlight to study the influence of light intensity as well as by wrapping the reaction tubes with colored cellophane filters (violet, green, yellow and red) to investigate the effect of light color on AgNP synthesis. It was observed that the violet filter enhanced the AgNPs synthesis appreciably. The FTIR spectroscopic analysis confirmed participation of bio-molecules with hydroxyl and amide groups present in the almond extract as reducing and capping or stabilizing agents, respectively. Dynamic light scattering (DLS) studies revealed the particle size distribution of nano-particles as 2 -400 nm, and scanning electron microscopy (SEM) confirmed their spherical shape with an average size of about 20 nm. Growth analysis of AgNPs revealed an increase in number of nano-particles with time, whereas their rate of growth decreased gradually. The AgNP suspension was stable even beyond 3 weeks.
