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 ...

Photosensitizers Mediated Photodynamic Inactivation against Fungi [PDF]

Nanomaterials, 2021
Superficial and systemic fungal infections are essential problems for the modern health care system. One of the challenges is the growing resistance of fungi to classic antifungals and the constantly increasing cost of therapy.

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.

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.

A Comparison of Porphyrin Photosensitizers in Photodynamic Inactivation of RNA and DNA Bacteriophages

Viruses, 2021
Effective broad-spectrum antiviral treatments are in dire need as disinfectants and therapeutic alternatives. One such method of disinfection is photodynamic inactivation, which involves the production of reactive oxygen species from dissolved oxygen in ...

Riboflavin in photodynamic inactivation of pathogens and photodynamic therapy [PDF]

Annals of Mechnikov's Institute, 2020
Riboflavin, besides its key role in providing cellular metabolism in humans and animals, is used as a compound of antimicrobial photodynamic therapy (aPDT) owing to its photosensitizing capability. PDT is a promising approach for the photoinactivation of
