Recently, there has been a significant focus on plasmonic nanostructures as an alternative to chemical dyes for managing color blindness due to their remarkable characteristics and the tunability of plasmonic resonances. In this work, the plasmonic glasses based on silver nanoparticles with a TiO₂ thin layer coating were fabricated using the sputtering technique and proposed for blue-yellow (tritanopia) CVD management. The proposed plasmonic glasses based on silver nanoparticles are more selective than commercial Enchroma glasses because of the tunability of plasmonic properties of silver nanoparticles by controlling their morphology, which provides insights for applications of color vision deficiency improvement. Also, the antibacterial activity of the proposed plasmonic glasses based on silver nanoparticles was investigated against E. coli and S. aureus bacteria, which have exhibited effective antibacterial properties. The results indicate that the silver nanoparticle-based glasses not only aid in tritanopia management but also offer potential for antibacterial applications such as implant coatings.</span></span></span> Color vision deficiency (CVD), silver nanoparticles, antibacterial, localized surface plasmon resonance. 175 184 http://ijop.ir/browse.php?a_code=A-10-175-14&slc_lang=en&sid=1 neda Roostaei n_roostaei@sbu.ac.ir 10031947532846005168 10031947532846005168 Yes Magneto-plasmonics Lab, Laser and Plasma Research Institute, Shahid Beheshti University, Tehran, Iran seyedeh Mehri Hamidi m_hamidi@sbu.ac.ir 10031947532846005169 10031947532846005169 No Magneto-plasmonics Lab, Laser and Plasma Research Institute, Shahid Beheshti University, Tehran, Iran
