Area of Science:

• Biomedical Engineering
• Organic Chemistry
• Oncology

Background:

• Cancer remains a significant global health challenge, driving research for less invasive and more effective treatments.
• Photodynamic therapy (PDT) and photothermal therapy (PTT) show promise for tumor inhibition with minimal damage to healthy tissues.
• Fluorescent molecular imaging (FMI) is crucial for early cancer detection, and its integration with PDT/PTT offers a noninvasive treatment strategy.

Purpose of the Study:

• To investigate modifications of aza-BODIPY derivatives to enhance their utility in cancer phototherapy and detection.
• To explore the potential of advanced aza-BODIPY compounds as versatile tools for cancer treatment strategies.

Main Methods:
