Photodynamic Inactivation of Human Coronaviruses [PDF]
Viruses, 2022 Photodynamic inactivation (PDI) employs a photosensitizer, light, and oxygen to create a local burst of reactive oxygen species (ROS) that can inactivate microorganisms.

Photodynamic Inactivation of Mammalian Viruses and Bacteriophages [PDF]
Viruses, 2012 Photodynamic inactivation (PDI) has been used to inactivate microorganisms through the use of photosensitizers. The inactivation of mammalian viruses and bacteriophages by photosensitization has been applied with success since the first decades of the ...

The application of photodynamic inactivation to microorganisms in food
Food Chemistry: X, 2021 Nowadays, food safety issues have drawn increased attention due to the continual occurrence of infectious diseases caused by foodborne pathogens, which is an important factor causing food safety hazard. Meanwhile, the emergence of an increasing number of

Photodynamic Inactivation of Herpes Simplex Viruses [PDF]
Viruses, 2018 Herpes simplex virus (HSV) infections can be treated with direct acting antivirals like acyclovir and foscarnet, but long-term use can lead to drug resistance, which motivates research into broadly-acting antivirals that can provide a greater genetic ...

Photodynamic Inactivation Of Rubella Virus [PDF]
Journal of Medical Microbiology, 1972 Summary Rubella virus possesses inherent photosensitivity and slowly loses infectivity when exposed to light. Sensitisation with proflavine markedly increases the rate of photoinactivation, and loss of infectivity, without loss of haemagglutinin activity, is most readily achieved at pH 9·0.

Photodynamic Therapy in the Inactivation of Microorganisms [PDF]
Antibiotics, 2020 The growing emergence of microbial resistance to conventional antimicrobials, due their dissemination in the environment, and excessive or inadequate prescriptions, associated with the globalization of pathogenic microorganisms’ transmission, make the discovery of new effective therapies to combat infection of extreme urgency [...]

Photosensitizing proteins for antibacterial photodynamic inactivation [PDF]
Translational Biophotonics, 2020 AbstractWe review recent applications of water‐soluble proteins as carriers for photosensitizing molecules in antimicrobial photodynamic therapy (aPDT). The low water solubility of photosensitizers and their tendency to aggregate often impair their photophysics, thus resulting in lower bioavailability of the compounds.

Antimicrobial Photodynamic Inactivation and Photodynamic Therapy for Infections [PDF]
, 2010 Photodynamic therapy (PDT) was initially discovered over 100 years ago by its ability to kill microorganisms, but its use to treat infections clinically has not been much developed. However, the present relentless increase in antibiotic resistance worldwide and the emergence of strains that are resistant to all known antibiotics has stimulated research

Halo-fluorescein for photodynamic bacteria inactivation in extremely acidic conditions
Nature Communications, 2021 Photodynamic inactivation is a common antibacterial method but often fails in extremely acidic environments (pH< 4). Here, the authors demonstrate halogenation of fluorescein for the development of a photodynamic agent which works in extremely acidic ...
