Nanoparticles are increasingly used in a variety of applications, including drug delivery, imaging, and diagnostics. However, there is still much that is not known about how nanoparticles interact with biological systems. One important area of research is understanding how nanoparticles bind to blood proteins at interfaces.
When nanoparticles come into contact with blood, they are immediately coated with a layer of proteins. This protein corona can affect the nanoparticle's circulation time, targeting, and toxicity. Therefore, it is important to understand the factors that influence protein corona formation.
One of the key factors that determines protein corona formation is the nanoparticle's surface properties. The charge, hydrophobicity, and size of the nanoparticle can all affect the type and amount of proteins that bind to it.
In a recent study, researchers from the University of California, Berkeley used a combination of experimental and computational techniques to investigate how nanoparticles bind to blood proteins at interfaces. The researchers found that the nanoparticle's surface charge and hydrophobicity were the most important factors in determining protein corona formation.
The researchers also found that the protein corona could be modulated by changing the nanoparticle's surface properties. For example, by making the nanoparticle more hydrophilic, the researchers were able to reduce the amount of proteins that bound to it.
This study provides new insights into how nanoparticles interact with blood proteins at interfaces. This information could be used to design nanoparticles that have the desired protein corona for a specific application.
