Nanobiotechnological modification of hemoglobin and enzymes from this laboratory

Polyhemoglobin is formed by the nanobiotechnological assembling of hemoglobin molecules into soluble nanodimension complex. A further step involves the nanobiotechnological assembly of hemoglobin, catalase and superoxide dismutase into a soluble nanodimension complex. This acts both as oxygen carrier and antioxidant to prevent the oxidative effects of hemoglobin. A further step is the preparation of nanodimension artificial red blood cells that contain hemoglobin and all the enzymes present in red blood cells. Other approaches include a polyhemoglobin–fibrinogen that acts as an oxygen carrier with platelet-like activity, and a polyhemoglobin–tyrosinase to retard the growth of a fatal skin cancer, melanoma.
