摘要：

The current study discussed with sensitive L-Methionine (L-Met) sensor relative on a graphene oxide (GO) modified screen. printed carbon electrode (SPCE) was developed. The fabricated GO/SPCE displayed an enhanced current (I-pa) response towards L-Met relative to that of a bare SPCE. Under optimum conditions, the GO/SPCE showed a wide linear range at L-Met concentrations of 2-96 mu M. The lower level of detection of 0.18 mu M, and sensitivity of about 6.75 mA mM(-1)cm(-2). The fabricated sensor displays good stability, reproducibility, and repeatability.
