Abstract

High molecular weight polymeric materials, which have incorporated within their structure modified protein(s), carbohydrate(s), nucleic acid(s), and/or lipid(s), capable of either transferring to blood, other biological fluid(s) or tissue(s), a desired substance(s), such as, for example, oxygen, selected antibody(ies), trace element(s), radioactively tagged structure(s), nutrient(s), enzyme(s), and/or other organic or inorganic chemical(s), drug(s) and pharmaceutical(s) of therapeutic value, or of extracting from blood, other biological fluid(s) or tissue(s), an undesired substance(s), such as, for example, carbon dioxide, toxic metabolic product(s), drug(s), and/or other organic or inorganic chemical(s), element(s), or deleterious substance(s). These polymeric materials are compatible with blood, other biological fluid(s) and tissue(s). They may be modified or combined so that the transfer of desired substance(s) to the blood, biological fluid(s) or tissue(s) can be carried out either simultaneous with, prior to, or subsequent to the extraction of undesirable substance(s) from blood, biological fluid(s) or tissue(s).
