Objective To evaluate the value of using agold nanorod(GNR)optical immunosensor to diagnose schistosomiasis in its early stages. Methods GNRs were prepared by seed-mediated growth and were deposited onto ITO glass slides.SIEA26-28 ku SjscFv antibody was bound to the solid phase sensor.An optical immunosensor based on local surface plasmon resonance(LSPR)was used to detect Schistosoma japonicum antigens in serum at different times(1week,2weeks,4weeks,6weeks,and 8weeks),resulting in better optical recognition...
