Nanocarrier Binding (IMAGE) University of Pennsylvania Caption Previous work by some of the researchers uncovered a counter-intuitive relationship that suggested that adding more targeting molecules on the nanocarrier's surface is not always better, as increases in stability may come with decreases in targeting specificity. Understanding the role the fluttering of the target cell's surface plays in this equation is necessary for better design of nanocarriers.
