Cellulose is one of the most abundantly available natural polymers. Carboxymethyl cellulose (CMC) belongs to the cellulose family and has different degrees of substitution. Current research comprises the fabrication and characterization of CMC nanofibers using polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) as capping agents and carriers for sustainable food packaging applications. Recently authors successfully fabricated smooth and uniform nanofibers of stated polymers and optimized the ratios of three polymers for continuous production. However, in this research, it was further characterized for mechanical properties, surface properties, structural properties, air permeability, and chemical properties to confirm the suitability and scope of tri-component nanofibrous mats in food packaging applications. Different fruits and vegetables were packed in a plastic container and closed by nanofiber mats and by a plastic lid. All samples were observed after a specific period of time (fruits were kept for 40 days while vegetables were kept for 10 days in the controlled environment). It was observed in the results that fruits and vegetables closed by nanofiber based webs exhibited better freshness and lower accumulation of moisture as compared to that of containers with plastic lids. From the results of performed tests, it was observed that nanofiber mats possess enough mechanical, structural, and morphological properties to be used as food packaging.

In this study, the dual functional wound dressings for diabetic patients were fabricated with the help of gentamicin/ cellulose acetate by electrospinning. The resultant nanofibers were functionalized with silver nanoparticles (AgNPs) on its surface by a simple facile wetting process. Herein, gentamicin (Ge) was used for the objective to heal the infection inflammation and Ag NPs were loaded for the antibacterial properties. The resultant CA/Ge/Ag nanofibers were characterized for morphology analysis, chemical interactions examination, release behavior, structure analysis and antibacterial efficiency by scan electron microscope/ transmission electron microscope, FTIR/XPS, ICP study, XRD study and disc diffusion method of antibacterial, respectively. Based on characterization results it was concluded that all samples of CA/Ge/Ag nanofibers showed the antibacterial properties and appreciable release behavior.
