Journal of the Royal Society of Medicine, 1999 Photodynamic therapy (PDT) of malignant tumours is a new technique for treating cancers. After intravenous injection, a photosensitiser is selectively retained by the tumour cells so after time there is more sensitiser in the tumour than in the normal adjacent tissue. The photosensitiser must be able to absorb the wavelength of light being delivered to

Microscopic study of cultural and diffusion kinetics of the effects of a prototype extracellular matrix on the photodynamic therapy of periopathogenic bacteria – a pilot study [PDF]
Folia Medica, 2023 Introduction: In dental medicine, photodynamic therapy is a promising treatment for bacterial infections. Oral biofilms, on the other hand, can produce an extracellular matrix that provides protection and stability against external forces.

JNCI Journal of the National Cancer Institute, 1998 Photodynamic therapy involves administration of a tumor-localizing photosensitizing agent, which may require metabolic synthesis (i.e., a prodrug), followed by activation of the agent by light of a specific wavelength. This therapy results in a sequence of photochemical and photobiologic processes that cause irreversible photodamage to tumor tissues ...

Photodynamically Active Electrospun Fibres for Antibiotic-Free Infection Control [PDF]
, 2021 Antimicrobial biomaterials are critical to aid in the regeneration of oral soft tissue and prevent or treat localised bacterial infections. With the rising trend in antibiotic resistance, there is a pressing clinical need for new antimicrobial chemistries and biomaterial design approaches enabling on-demand activation of antibiotic-free antimicrobial ...

Photodynamic therapy using systemic administration of 5-aminolevulinic acid and a 410-nm wavelength light-emitting diode for methicillin-resistant Staphylococcus aureus-infected ulcers in mice. [PDF]
PLoS ONE, 2014 Bacterial resistance to antibiotics has become a worldwide problem. One potential alternative for bacterial control is photodynamic therapy. 5-aminolevulinic acid is a natural precursor of the photosensitizer protoporphyrin IX. Relatively little is known
