| Özet |
| In this study, an electrochemical biosensor based on carbon nanofibers (CNF), ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate (IL), poly(glutamic acid) (PGA) and tyrosinase (Tyr) modified screen printed carbon electrode (SPE) was constructed for tyramine determination. Optimum experimental parameters such as CNF and IL amount, polymerization conditions of glutamic acid, enzyme loading, pH of test solution and operating potential were explored. The construction steps of the Tyr/PGA/CNF−IL/SPE were pursued by scanning electron microscopy and cyclic voltammetry. The Tyr/PGA/CNF−IL/SPE biosensor exhibited linear response to tyramine in the range of 2.0 × 10−7 – 4.8 × 10−5 M with a low detection limit of 9.1 × 10−8 M and sensitivity of 302.6 μA mM−1. The other advantages of Tyr/PGA/CNF−IL/SPE include its high reproducibility, good stability and anti-interference ability. The presented … |
