| 英文摘要 | In order to explore the clinical application of the nanobiosensor based on localized surface plasmon resonance (LSPR), we used our LSPR biosensor to detect the microalbuminuria in this work. The sliver nanoparticles were fabricated by using nanosphere lithography. The anti-human albumin antibody was immobilized on the sensor surface by amine coupling method. The different concentrations of commercial albumin and albumin in urine samples from three mild preeclampsia patients were determined according to the peak of LSPR extinction spectra. Under optimum conditions, our results showed that the biosensor displayed a detection limit of 1 ng/ml and wide dynamic range of 1 ng/ml to 1 mu g/ml. Furthermore, the microalbuminuria of three patients was determined by our biosensor within a short assay time, without sample purification. This biosensor proposed herein is easy to prepare and could be used for low-cost, rapid, label-free, and sensitive screening of the microalbuminuria. This approach provides a promising platform for developing clinical diagnostic applications. |
