Journal ArticleDOI
Metallophthalocyanine-based molecular materials as catalysts for electrochemical reactions
TL;DR: In this article, the authors show that the formal potential of a metallophthalocyanine complex needs to be in a rather narrow potential window for achieving maximum activity, probably corresponding to surface coverages of an M-molecule adduct equal to 0.5.
Journal ArticleDOI
Simultaneous Determination of Ascorbic Acid, Dopamine and Uric Acid with Chitosan‐Graphene Modified Electrode
TL;DR: In this article, a chitosan-graphene modified glassy carbon electrode showed high electrocatalytic activity towards oxidations of ascorbic acid (AA), dopamine (DA) and uric acid(UA).
Journal ArticleDOI
Preparation and characterization of PtAu hybrid film modified electrodes and their use in simultaneous determination of dopamine, ascorbic acid and uric acid.
TL;DR: The modified electrode was quite effective not only to detect DA, AA and UA individually but also in simultaneous determination of these species in a mixture as well as for the determination of DA,AA and UA in dopamine injection solution, vitamin C tablets and human urine samples.

Chemically modified electrodes for electrochemical detection of dopamine in the presence of uric acid and ascorbic acid: A review
Muhammad Sajid,Mazen K. Nazal,Muhammad Mansha,Abdulnaser Alsharaa,Shehzada Muhammad Sajid Jillani,Chanbasha Basheer +5 more
TL;DR: In this paper, the authors reviewed the materials that have been extensively used to fabricate modified electrode surfaces for detection of dopamine in real samples and discussed the characteristics of these materials that improve the electrocatalytic activity of the modified surfaces.

The substantia nigra of the human brain. II. Patterns of loss of dopamine-containing neurons in Parkinson's disease.
TL;DR: The spatiotemporal progression of neuronal loss related to disease duration can be drawn in the substantia nigra pars compacta for each Parkinson's disease patient: depletion begins in the main pocket (nigrosome 1) and then spreads to other nigrosomes and the matrix along rostral, medial and dorsal axes of progression.

Simultaneous electroanalysis of dopamine and ascorbic acid using poly (N,N-dimethylaniline)-modified electrodes.
TL;DR: Hydrophobicity of the polymer film shows great influence on the voltammetric responses of both DA and AA, and the electrode exhibits the stable and sensitive response to DA.
