Interactions Between Polymer Nanoparticles And Blood Plasma Applied To Drug Delivery Systems, Mark Bannon

Theses

Targeted nanoparticle drug delivery has the potential to replace current forms of cancer therapy with previously unparalleled efficiency. Upon introduction into the human body, nanoparticles exhibit a substantial increase in diameter due to a biomolecular corona formation caused by interactions between blood plasma proteins and the nanoparticles. These interactions must be analyzed and understood for targeted delivery to reach its potential in both feasibility and efficiency.

To study the formation of the protein corona, polystyrene nanoparticles were incubated in vitro in goat blood plasma for 10-minute intervals, diluted to different degrees and then measured to obtain the hydrodynamic diameter of …
