We showed that carboxyl-functionalized graphene oxide (carboxyl-GO) biosensing materials are capable of accurate detection.Methods: We developed a carboxylated GO-based surface plasmon resonance (SPR) aptasensor suitable for screening Down’s syndrome in clinical serum. This biosensing material could rapidly and accurately detect hCG protein with a low concentration to identify fetal Down’s syndrome. The developed carboxyl-GO-based SPR aptasensor showed excellent sensitivity and limit of detection without the use of antibodies and without any specific preference.Results: hCG protein detection limits of 1 pM in buffer samples and 1.9 pM in clinical serum samples were achieved. The results showed that the carboxyl-GO-based chip could detect hCG well below the normal physiological level of serum protein (5.0 mIU/mL). High affinity, sensitivity, and better detection limit were obtained in the range of 1.9 pM to 135 pM. The results showed a 5k-fold dilution factor, and that an SPR angle shift of more than 20 millidegrees (mo) was associated with a significant risk of fetal Down’s syndrome compared to normal pregnant women. The results clearly showed that the detection of hCG protein in serum samples from pregnant women at 12– 19 weeks could be used to screen Down’s syndrome with high selectivity and sensitivity.Conclusion: Our findings suggest the potential application of carboxyl-GO film in proof-of-concept studies for serum assays as a new type of SPR material. In addition, peptide and carboxyl-GO films may be conducive to the development of future point of care testing and rapid diagnostic devices for other diseases such as cancer.Keywords: surface plasmon resonance, SPR, aptasensor, carboxyl-functionalized graphene oxide, GO-COOH, peptides, human chorionic gonadotropin, hCG, Down’s syndrome, DSChiu NFWang YHChen CYDove Medical Pressarticlesurface plasmon resonance (spr)aptasensorcarboxyl-functionalized graphene oxide (go-cooh)peptideshuman chorionic gonadotropin (hcg)down's syndrome (ds)Medicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 8131-8149 (2020)
