The NIH has awarded us a two-year R21 grant in the amount of $420,025 to support our project “Surface Active Polyelectrolyte Nanomedicine for Treatment of Lung Infections in Cystic Fibrosis.” This support will allow us to study and optimize the mucus and biofilm penetrating properties of our polyelectrolyte-based nanoparticles, which will ultimately enable improved delivery to and treatment of infections in cystic fibrosis.
