موضوع به انگلیسی:Development of smartphone-based ECL sensor for dopamine detection:
Practical approaches
بخشی از متن:In this work, a compact, mobile phone-based ECL sensor apparatus was developed using the phone cameras,
screen-printed electrodes (SPE), and mobile app for dopamine detection. Methods of DC voltage application
for ECL reactionwere comprehensively studied fromthemobile phone itself or external power. Under optimized
sensing conditions, with disposable carbon SPE and 20 mM coreactant tri-n-propylamine (TPrA), acceptable repeatability
and reproducibility were achieved in terms of relative standard deviation (RSD) of intra- and
interassays, which were 6.7 and 5.5%, respectively. The biochemical compound dopamine was measured due
to its ECL quenching characteristics and its clinical importance. The quenching mechanism of Ru(bpy)3
2+/TPrA
by dopamine was investigated based on the estimation of the constants of the Stern-Volmer equations. The linear
range for detectable dopamine concentration was from 1.0 to 50 μM (R2 = 0.982). As the developed mobile
phone-based ECL sensor is simple, small and assembled from low-cost components, it offers new opportunities
for the development of inexpensive analytical methods and compact sensors
