Formation and characterization of stable human serum albumin-tris-malonic acid [C60]fullerene complex

The preparation and characterization of the stable human serum albumin (HSA)-C-3 isomer of trismalonic acid [C-60] fullerene complex is reported. Other than the anti-fullerene antibody, a stable protein -fullerene complex with a native protein has never been observed. This study may provide valuable answers to the growing concern regarding the effects of carbonaceous nanomaterials on human health on one hand and, on the other, may lead to the development of novel antioxidant therapeutic agents, radiopharmaceuticals, and components for bioelectronic devices.
