A novel electrochemical sensor based on bottlebrush-likeZnO nanowires decorated on carbon nanofibers for highly specific and sensitivedetection of silymarin in biologicalsamples |
| 초록 |
In this work, electro-etched carbon nanofibers(CNFs) were coated with bottlebrush-like zinc oxide (ZnO) nanowires via afacile hydrothermal method for the preparation of a CNF-ZnO nanocomposite as apromising electrode material for the trace level detection of silymarin. Thefabricated CNF-ZnO glassy carbon electrode (GCE) demonstrated a higher anodicpeak current, lower peak potential, and excellent sensing performance ofsilymarin compared to GCEs fabricated with ZnO or CNFs. The CNF-ZnO-GCEexhibited an appreciable linear response range (2–123 nM), good sensitivity(1.728 μA∙nM−1 cm2), and an ultra-low detection limit(1 nM). We also successfully showcased its specific sensing behavior for thesensing of silymarin in the presence of structurally similar compounds andmetal ions. Furthermore, the CNF-ZnO-GCE was effectively applied to realbiological and pharmacological samples for the efficient determination ofsilymarin, with which we obtained satisfactory recovery values. |
