Photocatalytic Effect of TiO2 Films on Viruses and Bacteria

Polyelectrolyte complex materials from chitosan and gellan gum

“…An antimicrobial effect can be achieved by eluting germicidal compounds such as silver ions, titanium dioxide and iodine from the wound dressing [71][72][73] .…”

“…TiO 2 films also exhibited an antiviral effect by causing significant changes in the virus structure and resulting in the loss of the ability by the virus to attack host cells 72 . Other reports showed the ability of TiO 2 to destroy Hepatitis B virus surface antigen (HBsAg) 257 .…”

Inactivation of Goose Parvovirus, Avian Influenza Virus and Phage by Photocatalyst on Polyethylen Terephthalate Film under Light Emitting Diode (LED)

“…They have attracted attention as environmentally friendly substances for inactivating pathogens. The most well-known photocatalyst is titanium oxide (TiO 2 ), and many reports have shown its disinfection effect towards various microorganisms under ultraviolet (UV) radiation [1,3,4,5,8,13,22]. Recently, several papers on TiO 2 under visible light radiation were published, but the methods they described required a long incubation period (24 hr) to inactivate viruses [16].…”

Chapter Green Nanotechnology: Development of Nanomaterials for Environmental and Energy Applications

“…Photocatalytic oxidation using semiconductors as catalysts has become an attractive candidate as a green technology for environmental applications, such as water cleaning (1), air purification (2), and soil remediation (3) ever since Fujishima and Honda (4) discovered the photoinduced water cleavage of TiO 2 . Photocatalysis has been employed to degrade toxic organic compounds, dyes, pesticides, volatile organic compounds, harmful gases, and bacteria (3,(5)(6)(7)(8)(9) in different media. Therefore, photocatalysis has been intensively studied over the last two decades as a clean and green process to decompose pollutants in the environment.…”
