A novel approach including only one stage of ecofriendly treatment, by sodium bicarbonate, followed by mechanical grinding was used to isolate the nanofibers from waste sugarcane bagasse subjected to its characterization for the packaging applications. The result of dynamic light scattering (DLS) analysis was found in line with the result of transmission electron microscopy (TEM) to confirm the nanosize of developed nanofibers. The X-ray diffraction analysis showed the highest crystallinity of nanofibers than those of untreated and treated fibers. The removal of hemicelluloses and lignin from treated fibers and nanofibers was confirmed by Fourier transform infrared (FTIR) analysis. Moreover, a good thermal stability of nanofibers was also confirmed by thermogravimetric analysis (TGA). The optical properties (ie, absorbance and transmittance) in wavelength range 200 to 700 nm were also measured using UV-visible spectroscope. An excellent optical and antibacterial property against Escherichia coli (E. coli) and Bacillus bacteria along with better strength and stiffness was offered by the isolated nanofibers, which makes them the most suitable reinforcement to be used in polymeric composites for the packaging applications.

Sodium alginate (Na-Alg) is water-soluble, neutral, and linear polysaccharide. It is the derivative of alginic acid which comprises 1,4-β-d-mannuronic (M) and α-l-guluronic (G) acids and has the chemical formula (NaC6H7O6). It shows water-soluble, non-toxic, biocompatible, biodegradable, and non-immunogenic properties. It had been used for various biomedical applications, among which the most promising are drug delivery, gene delivery, wound dressing, and wound healing. For different biomedical applications, it is used in different forms with the help of new techniques. That is the reason it had been blended with different polymers. In this review article, we present a comprehensive overview of the combinations of sodium alginate with natural and synthetic polymers and their biomedical applications involving delivery systems. All the scientific/technical issues have been addressed, and we have highlighted the recent advancements.

“…The incorporation of CNF (5% w/w) into the CMC matrix caused a significant improvement of the mechanical properties in comparison with CMC. Similarly, composite biosponges of SA reinforced with CNF were prepared [124], determining a noteworthy enhancement in the mechanical performances and the thermal stability for SA-based composite biosponges. Moreover, the sponges loading with Oryza sativa and Tinospora cordifolia extracts imparted additional antibacterial functionality to the composite against E. coli and P. aeruginosa.…”

Site-Specific release of active molecules with antimicrobial activity spurred the interest in the development of innovative polymeric nanocarriers. In the preparation of polymeric devices, nanotechnologies usually overcome the inconvenience frequently related to other synthetic strategies. High performing nanocarriers were synthesized using a wide range of starting polymer structures, with tailored features and great chemical versatility. Over the last decade, many antimicrobial substances originating from plants, herbs, and agro-food waste by-products were deeply investigated, significantly catching the interest of the scientific community. In this review, the most innovative strategies to synthesize nanodevices able to release antimicrobial natural extracts were discussed. In this regard, the properties and structure of the starting polymers, either synthetic or natural, as well as the antimicrobial activity of the biomolecules were deeply investigated, outlining the right combination able to inhibit pathogens in specific biological compartments.
