The formation of a polyeugenol-modified gold electrode is also reported for the first time.916-918engcysteineselective electrodeseugenolglassy carbonModifying glassy carbon (GC) electrodes to confer selectivity for the voltammetric detection of L-cysteine in the presence of DL-homocysteine and glutathioneArtigo10.1002/elan.200704151WOS:000255648900013Acesso restrito0072173018005712
