Making masks with antibacterial properties and the ability to detect paint contamination

In this study, we have studied the fabrication of nanofibers composed of silver nanoparticles. These nanofibers were produced by applying different voltages (from 10 to 20 kV). The structure and properties of these nanofibers were investigated using analytical techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL) spectroscopy. Antibacterial tests have also shown that these nanofibers have antibacterial properties. Also, microscopic images of nanofibers with different voltages indicate significant differences in the structure and properties of nanofibers at different voltages. Finally, photoluminescence spectroscopy of nanofibers containing silver nanoparticles was also evaluated and the effect of pollution and bacteria on the luminescence properties was critically examined. This final research advances the design of smart masks with antibacterial properties and the ability to identify the color of pollution and offers new possibilities for controlling and preventing the spread of diseases.
