A sensor for methanol was fabricated by incorporating the antibiotic cefixime (CEF) along with Ni(II) ion into a chitosan membrane matrix. Sensing is based on the electrocatalytic effect that the complex membrane exerts on the electro-oxidation of methanol. The resulting CEF-Ni(II)/chitosan glassy carbon (GC) electrode had a good electrocatalytic activity to the electro-oxidation of methanol in alkaline...
A sensitive method for the determination of estradiol is presented that is based on an electrode modified with multi-walled carbon nanotubes (MWNTs) along with an ionic liquid. The resulting electrode showed more sensitive voltammetric response to estradiol than other electrodes modified with MWNTs. The peak current for estradiol is linearly related to concentration over two decades, and the limit...
