Abstract:In this proof‐of‐concept study, ferrocene‐modified multiwalled carbon nanotubes (Fc‐MWCNT) were synthesized by amide coupling and the resulting product was characterized by transmission electron microscopy and Fourier‐transform infrared spectroscopy. The Fc‐MWCNT were used in a graphite paste electrode (GPE) for the highly sensitive simultaneous determination of dopamine (DA), uric acid (UA), xanthine (XA) by differential pulse voltammetry. The sensor displayed a linear range up to 4.5, 14, and 82.0 μM with a … Show more
“…The decrease in the slope could be attributed to kinetic limitations. 37 Calculated by the equation LOD = 3 σ / k , the LOD of sarcosine was 0.44 μM. And the LOQ of sarcosine was 1.45 μM.…”
Herein, a highly sensitive detection platform for the dual-mode determination of sarcosine by fluorescence and colorimetry was constructed based on zirconium-based metal organic frameworks (Zr-MOFs) with multi-enzyme immobilization. Zr-MOFs with...

“…[40][41][42] Previously, several important studies have addressed the development of the simultaneous detection of uric acid and dopamine using modified electrodes. [43][44][45][46][47] Nevertheless, to the best of our knowledge, there is still a real need for the development of a selective uric acid sensor in the presence of dopamine. A new development is demonstrated here based on an imprinted polymer on the ErGO/PEDOT:PSS modified electrode.…”
A molecularly imprinted polymer (MIP) with uric acid cavities increases the selectivity of uric acid measurement in the presence of dopamine as an interferent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
