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 3):
The method of  claim 1 , wherein said polyhemoglobin is form from hemoglobin extracted from red blood cells by lysing said red blood cells using a hypotonic lysis buffer.
