Electrochemical detection of dopamine using streptavidin-coated magnetic particles and carbon nanotube wiring

A novel sensor based on electrodeposited Au–Pt bimetallic nano-clusters decorated on graphene oxide (GO)–electrochemically reduced GO for sensitive detection of dopamine and uric acid

“…In contrast to the sensor previously reported [100], the optimized assay was able to detect endogenous DA or UA in un-diluted serum samples. But some literature has suggested that larger peaks which displayed higher DA or UA concentrations were not linear in the whole sample without or less dilution [99,[101][102]. These reported suggested that interference due to serum complicated composition (especially ascorbic acid) was proportionally higher for less diluted samples, which was in accordance with the results described by other authors.…”

Integrated paper-based electroanalytical devices for determination of dopamine extracted from striatum of rat

“…Dopamine could affect the brain process that controls emotional response, movement and the ability to experience pain and pleasure [1,2]. The variation of dopamine levels is associated with some diseases, such as Parkinson syndrome, sleeping disorders, memory declines and so on [3,4].…”

Ultrasensitive and Selective Detection of Dopamine Using Cobalt-Phthalocyanine Nanopillar-Based Surface Acoustic Wave Sensor

“…In the case of DA detection by commonly employed electrochemical methods, limitations are related to the fact that DA oxidized at almost the same potential as AA. Nevertheless, recent publications have highlighted several strategies to overcome this problem using new nanocomposites 5-10 , magnetic particles [11][12][13][14][15][16] , conducting polymer [17][18] , carbon nanotubes 19-25 and molecularly imprinted polymers as active layers [26][27][28][29][30] . However, the development of these electrochemical sensors requires yet large numbers of steps for fabrication.…”
