The International Photodynamic Association is calling for abstract submissions for the upcoming 18th World Congress in Tampere, Finland.

We are seeking abstracts for all research related to photodynamic action in diagnosis (PDD) and therapy (PDT) in all clinical and cosmetic applications. This includes but is not necessarily limited to 

  • Oncology, dermatology, antimicrobial, ophthalmology, immunology and other indications
  • Novel photosensitizer (organic, metal-based compounds and nanoparticles or nanoconstructs)
  • Photosensitizer targeting (new applications and indications)
  • New insights into the mechanisms, hypoxia and normoxia 
  • In silicon, in vitro, pre-clinical, translational and clinical studies can be submitted
  • PDT excitation mechanisms, by optical single photon and multi-photon excitation, ultrasound, x-ray are welcome
  • PDT dosimetry, light and photosensitizer, treatment monitoring and planning are also topics of the congress.
