Abstract
Products, such as devices, prostheses, and materials, whose surfaces have been modified in order to impart beneficial properties to these products are disclosed. The surface-modified products have improved biocompatibility compared to a corresponding product that lacks the modification. Following implantation in a subject, the surface-modified products induce a lower foreign-body response, compared to a corresponding unmodified product.
