Fluorimetric determination of dopamine in pharmaceutical products and urine using ethylene diamine as the fluorigenic reagent

Gold nanoparticle/double-walled carbon nanotube-modified glassy carbon electrode and its application

“…High performance liquid chromatography (HPLC) method [11] was described for the determination of DPH with expensive apparatus. Additionally, Wang et al [12] reported the determination of DPH by fluorophotometry with narrow linear range, lower upper limit, and higher standard deviation. The spectrophotometry [13,14] was also used for determination of DPH in injection solution and produce experimental error because of oxidation treatment for chromogenic reagent.…”

Spectrophotometric Determination of Dopamine Hydrochloride in Pharmaceutical, Banana, Urine and Serum Samples by Potassium Ferricyanide-Fe(III)

“…Wang et al 9 reported the determination of DPH by fluorophotometry, with a narrow linear range (0.02 -0.60 mg L -1 ), a lower upper limit, and a bigger standard deviation. The HPLC method 10 was described for the determination of DPH with an expensive apparatus.…”

Dopamine-Imprinted Polymers: Template-Monomer Interactions, Analysis of Template Removal and Application to Solid Phase Extraction

“…Several research groups have investigated the problems of detection sensitivity and selective determination methods for dopamine. Those methods include fluorimetry [4,5], spectrophotometry [6] and highly selective and sensitive determination with modified glassy carbon electrodes [7]. Recently, the molecular imprinting technique has been described as a versatile tool for cost-effective preparation of polymeric materials with affinity and selectivity towards specific desired molecules [8][9][10].…”
