The nanofibers were synthesized through the electrospinning method, employing a range of voltages (5 to 20 kV) to explore their structural and functional variations. Analytical techniques, including XRD, SEM, UV-VIS, and (PL), were employed to scrutinize the nanofiber structure and properties. The XRD analysis exposed distinct crystal planes in silver nanoparticles. Antibacterial tests revealed the remarkable antibacterial properties of these nanofibers, showcasing their efficacy in inhibiting the growth of coliform and pseudomonas bacteria. Furthermore, the PL spectroscopy of nanofibers containing silver nanoparticles and carbon nanoparticles were critically evaluated, considering the impact of pollution and bacteria on the nanofiber's photoluminescence. The findings open new avenues for controlling and preventing the spread of diseases, offering innovative solutions for respiratory protection in the face of environmental challenges.
