Quantification of Human Chorionic Gonadotropin by Bovine Serum Albumin Nanoparticles

Background and Aims: Some nanoparticles can be used in immunoassays to increase sensitivity. This study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (BSA NPs). Materials and methods: At first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. Then the concentration of β-subunit of human chorionic gonadotropin (βHCG) in the clinical samples was quantified by traditional enzyme-linked immunosorbent assay (ELISA), and then checked by the nano-immunoassay. Results: The Pearson’s correlation coefficient between ELISA and nano-immunoassay was high, i.e., ۰.۸۰. Relative sensitivity and specificity of this nano-immunoassay were reported ۹۷.۴% and ۹۶.۶%, respectively. Conclusions: BSA NPs can be applied in nano-immunoassays as a new structure, and as an example, βHCG can be detected by this novel assay.
