ABSTRACT:
The present invention relates to a method and apparatus for the encapsulation of biologically-active substances in red blood cell, characterized by an optionally automated, continuous-flow, self-contained electroporation system which allows withdrawal of blood from a patient, separation of red blood cells, encapsulation of a biologically-active substances in the cells, and optional recombination of blood plasma and the modified red blood cells thereby producing blood with modified biological characteristics. The present invention is particularly suited for use to encapsulate allosteric effectors of hemoglobin, thereby reducing the affinity of erythrocytes for oxygen and improving the release of oxygen from erythrocytes in tissues.
