Hydrothermally synthesized Ag-TiO2 nanofibers (NFs) for photocatalytic dye degradation and antibacterial activity

Engineering surgical face masks with photothermal and photodynamic plasmonic nanostructures for enhancing filtration and on-demand pathogen eradication

“…This figure indicates that the maximum reached temperature of a surgical mask under laser irradiation can be 32.56 °C which is not enough to eradicate pathogens. 36 To prepare and investigate specimens we utilized later for antibacterial studies (to be discussed whereafter), face masks were cut in circles and fixed at the bottom of 96-well plates. Fig.…”

“…34 Such photothermally effective nanoparticles can induce light-triggered photothermal disinfection (on request) and have a broadband absorption range to eradicate any potentially lingering germs. [35][36][37] Among plasmonic nanoparticles, gold nanoparticles (Au NPs) have been widely used in numerous scientific domains in recent years due to their optical and thermo-optical features. 31,[38][39][40] Localized surface plasmon resonance (LSPR), a physical phenomenon, enables Au NPs to produce a strong electromagnetic field at the nanoscale level.…”

Ag/Cr-TiO2 and Pd/Cr-TiO2 for Organic Dyes Elimination and Treatment of Polluted River Water in Presence of Visible Light

“…As an alternative to overcome these problems, different researchers worldwide have studied the doping of TiO 2 with metallic species such as Ag, Au, Co, Cu, Cr, Fe, Ni, Mn, Pt, and Ru [ 3 ], among many others. The modification of titania and other semiconductors with different metals led to improve photochemical properties by acting as electron traps, thus, avoiding the electron–hole pair recombination, reducing the bandwidth, or adding new energy levels to efficiently absorb visible light from the electromagnetic spectrum [ 4 , 5 , 6 ].…”
