- Title: Fluorine Doped Graphene Quantum Dots A new Photosensitizer Agent
Abstract
Abstract:
Halogen-decorated graphene quantum dots (X@GQDs) will be herein explored as a material platform for application in photodynamic therapy (PDT). GQDs have been extensively studied in biomedical areas such as bioimaging, bio-sensing and photothermal therapy due to their superior optical and physiochemical properties. Application of GQDs in PDT has been explored lately, but currently the main challenges are inadequate singlet oxygen (1O2) quantum yield (QY), poor solubility, and biocompatibility. In this talk, the synthesis of a new class of halogen (fluorine) containing GQDs (F@GQDs) will be described. The as-synthesized F@GQD sample demonstrates an average particle size below 3 nm with a fluorine doping content of around 2%. The synthesized F@GQDs show improved water solubility and biocompatibility, while emitting strong green fluorescence and QY slightly above 13%. Moreover, the photodynamic activity was successfully tested in bioassays (in vitro).
The Material Science & Engineering World Conference 2026 will take place from October 18-20, 2026, at Bangkok, Thailand, on the theme "Materials Shaping the Futur ...
