Hypothesis
A protein corona naturally exists on the surface of biological nanoparticles and can be preserved using photomodification.
Conclusion
The study successfully visualized a natural protein corona on biological nanoparticles for the first time, demonstrating the effectiveness of the photomodification method.
Supporting Evidence
- The study confirmed the presence of a protein corona on extracellular vesicles and lipoproteins.
- Photomodification was effective in fixing the protein corona on biological nanoparticles.
- Ultracentrifugation and sucrose gradient methods were used for isolating nanoparticles.
Takeaway
Scientists found a special layer of proteins on tiny particles in blood, which helps understand how these particles work in the body.
Methodology
The study used photomodification to fix the protein corona on biological nanoparticles isolated from fetal and newborn bovine serum, followed by transmission electron microscopy for visualization.
Limitations
The isolation methods used did not consistently preserve the protein corona on all types of nanoparticles.
