Abstract:
PEGylated polyhemoglobin nanocapsules are provided, wherein the nanocapsules each include a core including polyhemoglobin, a polymer shell encapsulating the core, a polydopamine layer on an exterior surface of the shell, and poly(ethylene glycol) adhered by the polydopamine to the shell. A method of forming PEGylated polyhemoglobin nanocapsules includes extracting hemoglobin from red blood cells. The method further includes polymerizing the hemoglobin to provide polyhemoglobin. The polyhemoglobin is then encapsulated in a plurality of polymer shells to form a plurality of polyhemoglobin nanocapsules. In addition, a polydopamine is deposited on an external surface of the polyhemoglobin nanocapsules. Poly(ethylene glycol) is then adhered to the polyhemoglobin nanocapsules with the polydopamine to provide a plurality of PEGylated polyhemoglobin nanocapsules.

Claim (Index 13):
A plurality of PEGylated polyhemoglobin nanocapsules, said nanocapsules each comprising:\n a core including polyhemoglobin; a polymer shell encapsulating said core having an exterior surface; a polydopamine layer on said exterior surface of said polymer shell; and poly(ethylene glycol) adhered by said polydopamine to said polymer shell.
