Abstract
BackgroundIron deficiency anemia (IDA) has been a major public health problem all over the world. Developing new iron (Fe) fortificants with both high bioavailability and negligible food sensory changes for IDA is in urgent demand.Material/MethodsThe Fe nanoparticles were fabricated through a one-pot reduction process under the protection of bovine serum albumin (BSA). The BSA-Fe nanoparticles were characterized systematically. The comparisons between BSA-Fe nanoparticles and FeSO4 in bioavailability were carried out through hemoglobin (Hb) repletion method. The biocompatibility of BSA-Fe nanoparticles was also investigated through in vitro and in vivo assays.ResultsBSA-Fe nanoparticles have super-small size and good water solubility as well as water stability. The Hb repletion assay demonstrated that BSA-Fe nanoparticles have comparative bioavailability with FeSO4. The in vitro cell viability assay, in vivo histological analysis, and biochemical measurements proved the remarkable biocompatibility of BSA-Fe nanoparticles.ConclusionsThe BSA-Fe nanoparticles fabricated through a one-pot facile method have good water solubility, comparative bioavailability with FeSO4, and acceptable biocompatibility, exhibiting good potential for further clinical translations.
