“…Just as some literatures was reported, DA was no found in the serum and the real sample detecting was based on the spiked sample analysis [95][96]. The normal lever of UA in serum was from 149 to 445 mM [95][96][97][98], and UA can be detected in this proposed method according the LOD.…”

“…The resulting pDA film can be easily oxidized at the ITO electrode [ 34 ]. Previously, we suggested a DA-detection method using pDA films on ITO electrodes in the presence of HZ, wherein the oxidation current of pDA increased proportionally to the concentration of DA [ 35 ]. By inverting the concept underlying the previously described method, pDA films can be used as electrocatalytic mediators for sensitive detection of HZ oxidation.…”

“…To meet this requirement, in this study we adopted poly(dopamine) (pDA) to modify electrodes to detect HZ. We used pDA as a modifier or an electrocatalyst [ 19 , 27 , 28 , 29 , 30 , 31 ], because pDA can be simply and quickly formed on many substrates in basic solutions [ 32 , 33 , 34 , 35 ].…”

We have developed a simple and selective method for the electrochemical detection of hydrazine (HZ) using poly(dopamine) (pDA)-modified indium tin oxide (ITO) electrodes. Modification with pDA was easily achieved by submerging the ITO electrode in a DA solution for 30 min. The electrocatalytic oxidation of HZ on the pDA-modified ITO electrode was measured by cyclic voltammetry. In buffer solution, the concentration range for linear HZ detection was 100 µM–10 mM, and the detection limit was 1 µM. The proposed method was finally used to determine HZ in tap water to simulate the analysis of real samples. This method showed good recovery (94%–115%) and was not affected by the other species present in the tap water samples.

“…DA ve UA'nın aksine AA'ya ait yükseltgenme pikinin belli bir döngüden sonra kaybolduğu görülmektedir. Bu durum, AA'nın DA ve UA ile karşılaştırıldığında GCE-MoSe2 elektrotunun yüzeyine farklı şekilde adsorplanması ile açıklanabilmektedir [22]. Bundan dolayı, bu çalışma kapsamında hazırlanan modifiye elektrotun DA ve UA'nın birlikte tayini için kullanılabileceği görülmektedir.…”

İki boyutlu (2D) geçiş metal dikalkojenit (TMD) malzemeler sundukları üstün özelliklerden dolayı son yıllarda çok dikkat çekmektedirler. Bu çalışmada, TMD malzemelerin önemli bir üyesi olan molibden diselenür (MoSe2) hidrotermal yöntem ile sentezlenmiş ve çeşitli yöntemlerle yapısal ve morfolojik açıdan incelenmiştir. Analiz sonuçları, MoSe2’ün birkaç katmanlı formda elde edildiğini göstermiştir. MoSe2 daha sonra elektrot modifikasyonunda kullanılmış ve dopamin (DA) ve ürik asitin (UA) eş zamanlı elektrokimyasal tayininde uygulanmıştır. Diferansiyel puls voltametri (DPV) ile gerçekleştirilen tayin çalışmalarından DA için 9.98 – 155 µM arasında ve UA için 19.96 – 310 µM arasında lineer tayin aralıkları belirlenmiştir. Aynı zamanda, geliştirilen sensör askorbik asit (AA) girişiminden etkilenmemekte, kararlı ve tekrar üretilebilir özelliklere sahiptir.
