Nowadays, several neurological disorders and neurocrine tumours are associated with dopamine (DA) concentrations in various biological fluids. Highly accurate and ultrasensitive detection of DA levels in different biological samples in real-time can change and improve the quality of a patient’s life in addition to reducing the treatment cost. Therefore, the design and development of diagnostic tool for in vivo and in vitro monitoring of DA is of considerable clinical and pharmacological importance. In recent decades, a large number of techniques have been established for DA detection, including chromatography coupled to mass spectrometry, spectroscopic approaches, and electrochemical (EC) methods. These methods are effective, but most of them still have some drawbacks such as consuming time, effort, and money. Added to that, sometimes they need complex procedures to obtain good sensitivity and suffer from low selectivity due to interference from other biological species such as uric acid (UA) and ascorbic acid (AA). Advanced materials can offer remarkable opportunities to overcome drawbacks in conventional DA sensors. This review aims to explain challenges related to DA detection using different techniques, and to summarize and highlight recent advancements in materials used and approaches applied for several sensor surface modification for the monitoring of DA. Also, it focuses on the analytical features of the EC and optical-based sensing techniques available.

“…Many research groups have applied the specially functionalized nanoparticles for in vivo or in vitro experiments of labeling, targeting, imaging, sorting, etc. [6,14]. Furthermore, the exquisite combinations of functionalities, briefly dual-mode or dual-function, could broaden the application range of the nanoparticles and derive the synergistic effects from their own characteristics.…”

We present that dual-modal silica nanoprobes based on surface enhanced Raman spectroscopy (SERS) and fluorescence, demonstrating the several combinations of two spectroscopic signals for the noble combinatorial nanoprobes (F-SERS dot). Their synthetic procedure was introduced and dual-modal spectroscopic analyses were performed as preliminary studies. Hopefully, F-SERS dots will be one of promising and multifunctional nanoprobes for the various in vitro and in vivo biological diagnoses and screenings.

“…A range of analytical techniques such as chromatography [10], spectrophotometry [11], chemiluminescence [12], capillary electrophoresis [13], FTIR and Raman spectrometry [14] and flow injection analysis using various methods of detection [15,16] are reported in the literature for detection of these biological molecules. All these methods have disadvantages, for example long analysis times, high costs, the requirement for sample pretreatment and compressing system, temperature control systems, separation systems and other spectrophotometric or electric detection systems and in some cases low sensitivity and selectivity [17,18].…”

A fast and simple method for synthesis of Cu x O-ZnO/PPy/RGO nanocomposite by electrochemical manner have been reported in this paper. For testing the utility of this nanocomposite we modified a GCE with the nanocomposite to yield a sensor for simultaneous determination of four analytes namely ascorbic acid (AA), dopamine (DA), uric acid (UA), and folic acid (FA). Cyclic voltammetry (CV) and Differential pulse voltammetry (DPV) selected for the study. The modified electrode cause to enhance electron transfer rate so overcome to overlapping their peaks and consequently having the ability to the simultaneous determination of AA, DA, UA, and FA. To synthesis confirmation of the nanocomposite, Field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and electrochemical impedance spectroscopy (EIS) were applied. The linearity ranges were 0.07-485 µM, 0.05-430 µM, 0.02-250 µM and 0.022-180 µM for AA, DA, UA, and FA respectively and the detection limits were 22 nM, 10 nM, 5 nM and 6 nM for AA, DA, UA, and FA respectively Also, the obtained electrode can be used for the determination of the AA, DA, UA, and FA in human blood, and human urine real samples.
