Direct electrochemical reduction of hematite decorated graphene oxide (α-Fe2O3@erGO) nanocomposite for selective detection of Parkinson's disease biomarker

Non‐enzymatic electrochemical detection of dopamine in blood serum based on porous nitrogen‐doped graphene/Fe 3 O 4 nanocomposites

“…Also, it can be obviously observed that I pa and I pc are both linearly proportional to the square root of the scan rate ( v 1/2 ) (Fig. 8 c ), indicating the electrochemical redox process of DA is diffusion controlled, not surface controlled [3].…”

“…Dopamine (DA) has been extensively studied since the 1950s because of its important role in the renal, hormonal, cardiovascular systems and regulations in the motion of the brain [1–3]. Abnormal levels of DA in the human body are relevant to many neurological conditions and diseases, such as Parkinson's disease, drug addiction etc.…”

Graphene‐Based Nanotechnology in Neurodegenerative Disorders

“…These nanostructures are n‐type semiconductors characterized by good electrochemical activity, large surface areas, and high electron transfer rates that ultimately enhance the coated sensors’ performance. Other metal‐based nanostructures that have been reported are gold (Au) nanowires [ 68 ] and nanoarrays, [ 69 ] gold, [ 70 ] silver (Ag), [ 71,72 ] platinum (Pt), [ 73,74 ] and hematite (α‐Fe 2 O 3 ), [ 75 ] nanoparticles, and finally gold [ 76 ] and manganese dioxide (MnO 2 ) nanorods. [ 77 ] Recently, metal dichalcogenides such as alpha‐manganese sulfide (α‐MnS) nanoparticles [ 78 ] and tin disulfide (SnS 2 ) nanorods [ 79 ] have been reported to improve the sensing ability of the fabricated sensors through enhancement of the electrochemical conductivity and structural stability.…”
