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 last century.

Photodynamic inactivation of oropharyngeal Candida strains

Phytomedicine, 2014
Oropharyngeal candidiasis (OPC) is an infection frequent in immunocompromised patients. Photodynamic therapy is an alternative to conventional treatments, based on the utilization of compounds that inhibit or kill microorganisms only under the effect of light, process known as Photodynamic Inactivation (PDI).

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. The botanical extract PhytoQuinTM is a powerful photosensitizer with antimicrobial properties.

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. These factors force the scientific world to intensify the search for alternative and more effective methods of treatment. This

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.

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

Photodynamic inactivation of verrucae vulgares. II

Acta Dermato-Venereologica, 1977
Photodynamic inactivation therapy, consisting of a double-blind, paired comparison treatment schedule, was used in treating 56 patients for recalcitrant, symmetrical verrucae vulgares. 0.1% proflavine in 100% dimethylsulphoxide (DMSO) and 0.1% neutral red in 100% DMSO were used as active dyes, and 1% picric acid in 100% DMSO and 1% color ruber in 100 ...
