Area of Science:

  • Biomedical Engineering
  • Optical Physics
  • Dermatology

Background:

  • Photodynamic therapy (PDT) is a promising cancer treatment requiring precise light delivery.
  • Homogeneous and reproducible illumination is crucial in clinical PDT to avoid undertreatment or overtreatment.
  • Current flexible light sources are limited in improving light delivery homogeneity.

Purpose of the Study:

  • To explore methods for developing side emitting optical fibers (SEOF).
  • To investigate the integration of SEOF into flexible structures for improved skin illumination in PDT.
  • To evaluate different flexible light-emitting fabric techniques.

Main Methods:

  • Development of SEOF through techniques like micro-perforations.
  • Integration of SEOF into flexible structures: light blankets, panels, and fabrics (embroidery-based and woven-based).
  • Performance evaluation of different fabric types based on fluence rate and light delivery homogeneity.

Main Results:

  • Four main techniques for SEOF integration were described.
  • Woven-based light emitting fabrics demonstrated the highest fluence rate.
  • Woven-based fabrics provided the best homogeneity in light delivery and good flexibility.

Conclusions:

  • SEOF integrated into flexible structures, particularly woven-based fabrics, significantly enhance light illumination for PDT.
  • Woven-based SEOF fabrics offer superior performance for homogeneous and flexible light delivery in photodynamic therapy.
  • This advancement holds potential for more effective and reproducible PDT cancer treatments.
