🧪 Understanding the Innovation
Graphene
quantum dots (GQDs) are zero-dimensional carbon nanomaterials known for their
remarkable optical, electronic, and surface functionalization properties. They
have gained attention in bioimaging, biosensing, and photothermal therapy.
However, their application in photodynamic therapy (PDT) remains limited due to
low singlet oxygen (¹O₂) quantum yield, poor solubility, and biocompatibility
challenges.
🔬 The Scientific Breakthrough
In this
keynote session, halogen-decorated graphene quantum dots (X@GQDs) are presented
as an advanced nanoplatform for oncological applications.
Special
focus is given to fluorine-doped graphene quantum dots (F@GQDs), engineered to
enhance photodynamic performance.
Key
features include:
- Particle size below 3 nm
- ~2% fluorine doping
- Improved water solubility
- Enhanced biocompatibility
- Strong green fluorescence
- Quantum yield slightly above
13%
Fluorine
incorporation improves electronic transitions, enabling more efficient singlet
oxygen generation — a critical parameter in effective PDT for cancer treatment.
🧫 Photodynamic Performance
In vitro
bioassays confirm successful photodynamic activity under light activation.
These findings demonstrate that F@GQDs hold strong potential as theranostic
agents, combining imaging and therapeutic capabilities within a single
nanoplatform.
