Sensitive Determination of Dopamine and Uric Acid by the Use of a Glassy Carbon Electrode Modified with Poly(3-methylthiophene)/Gold Nanoparticle Composites

Flower-like ZnO decorated polyaniline/reduced graphene oxide nanocomposites for simultaneous determination of dopamine and uric acid

“…Dopamine (DA,3,4-dihidroxyphenyl ethylamine) as one of the most important and representative catecholamine neurotransmitters, is a significant biomolecule that widely distributed in the body of many mammals that plays an important physiological role as an extra cellular chemical messenger for the central nervous, renal, and hormonal systems [1][2][3]. The abnormal DA levels could demonstrate some ills such as schizophrenia, Parkinson's disease, and HIV infection.…”

Electrochemical detection of 8-hydroxy-2′-deoxyguanosine as a biomarker for oxidative DNA damage in HEK293 cells exposed to 3-chloro-1,2-propanediol

“…22 However, these methods require complex sample pretreatment as well as pre-concentration with gradient elution during chromatographic separation. In contrast, a simple and rapid analytical method for trace detection of biochemical species is provided by the study of electrodes modied with conducting polymer lms, such as 3methylthiophene, 16,23,24 hippuric acid, 25 and trans-3-(3-pyridyl) acrylic acid. 26 Major advantages of these materials include highly conductive surfaces, a large number of reactive sites, catalytic properties, pre-concentration ability, and surfacefouling prevention.…”

Use of voltammetric analysis for fast and objective discrimination of the etiology, evolution, and bacterial infection of lower limb ulcers

“…Similarly, the discrimination of clinical course may be due to the presence of elastase and metalloproteinase, which are correlated with the degree of inflammation and catabolism of LU and with their prognosis . While we are not able to provide a qualitative/quantitative analysis of exudate, these hypotheses are supported by other evidence showing that VA is able to detect the presence of dopamine and uric acid in solution and to discriminate infected from noninfected urine …”
