“…The design principles for chemical sensing of catecholamines make use of fluorescence resonance energy transfer, photo-induced electron transfer (PET), photo-induced charge transfer, electrostatic interactions, excimer formation, ligand exchange method, catalytic and molecular beacon, fluorescence polarization, and fluorescent chemodosimetry [23]. According to a review paper by Gorbunova et al published in 2019, approximately 42% of all the methods used for catecholamine determination are based on high performance liquid chromatography (HPLC), followed by those based on electrochemistry (30%), spectrophotometry (13%), fluorescence spectroscopy (9%), and immunoassays (3%) [24]. This data fits perfectly with the sudden rise in the number of research papers in the late 1980s dealing with catecholamine determination as the availability of HPLC till then was not widespread.…”

The neurochemistry of catecholamines plays a crucial and complex role in human memory, behavior, and cognition, while affecting other organs such as the lungs, heart, liver, and skin. Dopamine, norepinephrine, and epinephrine are three closely-related catecholamines that have been widely studied over the last seven decades for development of medications for life-threatening diseases. Other studies have also suggested a link between drug abuse and catecholamine levels. The determination of catecholamine levels in different parts of the human body has also been a hot topic for research in these years. HPLC, spectrophotometry, fluorescence, electrochemistry and other techniques have been used to quantify catecholamines in mostly in biological samples like serum and urine, although in vivo studies are also possible. This article attempts to present the research on catecholamines from the perspectives of their bodily functions, development of medications for diseases related to these, and the techniques used for their detection and quantification.

“…In addition, the amount of catecholamines released by PC12 cells can be measured by fluorescence spectrophotometry. 46,47 In brief, 0.2 mL of 1 mol L À1 sodium hydroxide, 1 mL of UP water, and 0.05 mL of 0.5% (w/v) potassium ferricyanide were added to 1.5 mL of the sample and the reaction was allowed to take place for 2 min at room temperature. The reaction was then terminated by adding 0.2 mL of 10 mol L À1 vitamin Csodium hydroxide solution.…”

Two morphologically different porous gold layered on Cu-oxide-based electrochemical sensors were developed for the selective detection of dopamine in the presence of uric acid, ascorbic acid or dextrose. The nanoparticles were prepared by layering Au onto either a cubic or octahedron-shaped Cu-oxide crystal via a galvanic reaction. These were characterized with scanning electron microscopy, energy dispersive X-ray and X-ray photoelectron spectroscopy. The porous structure of the gold over layer was clearly visible on the scanning electron microscopy image while the macro morphology was maintained. X-ray photoelectron spectroscopy confirmed the presence of metallic gold while both CuI (CuO) and CuII (Cu2O) were present in the samples. These two Au/Cu-oxide nanocomposites were used to modify glassy carbon electrodes and were tested for their dopamine sensing ability. Differential pulse voltammetry was used to investigate the selectivity towards dopamine in the presence of different interfering molecules uric acid, ascorbic acid and dextrose). From the differential pulse voltammetry, the lowest limit of detection was found to be 1.1 μM, with a sensitivity of 3.4 μA mM−1 mm−2 in the linear range of 10–250 μM for the porous gold layered covering the octahedron Cu-oxide-modified glassy carbon electrode.
