Implication

Microfluidic platform demonstrates spatial treatment response in tumor microenvironment, indicating hypoxia limits effectiveness of photodynamic therapy.

Key Points

To develop a microfluidic culture model that simulates tumor conditions for evaluating photodynamic therapy.
Developed a microfluidic platform with agarose gel–embedded tumor cell culture.
Implemented dynamic perfusion and oxygen regulation for PDT studies.
Utilized computational fluid dynamics and discrete element method for chamber optimization.
Photodynamic therapy efficacy diminished under hypoxic conditions compared to normoxia.
Significant reactive oxygen species generation noted in normoxic conditions.
Cell viability decreased with increased light dose under normoxia, while hypoxic cultures maintained over 85% viability.
