Hypothesis
All dispersing media produce some degree of CNP agglomeration.
Conclusion
CNP agglomerates are present in all dispersing vehicles, with protein or lipid components leading to better dispersion.
Supporting Evidence
- CNP suspended in serum had the fewest large agglomerates.
- Different sources of CNP produced variable dispersion characteristics.
- Using PBS alone resulted in massive CNP clumps.
Takeaway
This study looked at how different liquids affect the clumping of tiny carbon particles. It found that using liquids with proteins or fats helps keep the particles from sticking together.
Methodology
CNP were suspended in various media and analyzed for agglomeration using light microscopy.
Limitations
The study does not address how different media affect CNP biological activity.
Participant Demographics
BALB/c mice were used for in vivo studies.
