Summary
Water-soluble graphene quantum dots (GQDs) show promise as a safe cell imaging probe. These GQDs enabled successful multiphoton fluorescence imaging of mouse primary hepatocytes without causing significant harm.
Area of Science:
- Biomedical Engineering
- Materials Science
- Nanotechnology
Background:
- Graphene quantum dots (GQDs) are emerging nanomaterials with unique optical properties.
- Developing safe and effective probes for cell imaging is crucial in biomedical research.
Purpose of the Study:
- To characterize water-soluble GQDs as a multiphoton fluorophore.
- To evaluate the potential of GQDs as a cell imaging probe for mouse primary hepatocytes.
- To assess the cytotoxicity of GQDs in cellular environments.
Main Methods:
- Systematic characterization of water-soluble GQDs.
- Incubation of mouse primary hepatocytes with varying concentrations of GQDs.
- Assessment of cell viability and cytotoxicity.
- Multiphoton fluorescence imaging of hepatocytes using GQDs.
Main Results:
- Water-soluble GQDs exhibited effective multiphoton fluorescence properties.
- No significant cytotoxicity was observed in mouse primary hepatocytes treated with GQDs up to 100 μg ml(-1).
- Successful imaging of mouse primary hepatocytes was achieved using the developed GQDs.
Conclusions:
- Water-soluble GQDs are a promising, non-toxic fluorescent probe for multiphoton imaging.
- GQDs offer a viable tool for visualizing cellular structures and functions in biological systems.
