Abstract:
Background: Parkinson’s disease (PD) is a long-term, degenerative, and neurological
disease in which a person loses control of certain body functions. The formulation
of novel effective therapeutics for PD as a neurodegenerative disease requires accurate
and efficient diagnosis at the early stages.
Objective: Analyzing data gathered by measurable signals converted from biological reactions
allows for qualitative and quantitative evaluations. Among various approaches reported
so far, biosensors are powerful analytical tools that have been used in detecting the
biomarkers of PD.
Methods: Biosensor’s biological recognition components include antibodies, receptors,
microorganisms, nucleic acids, enzymes, cells and tissues, and biomimetic structures.
This review introduces electrochemical, optical, and optochemical detection of PD biomarkers
based on recent advances in nanotechnology and material science, which resulted
in the development of high-performance biosensors in this field.
Results: PD biomarkers such as α-synuclein protein, dopamine (DA), urate, ascorbic acid,
miRNAs, and their biological roles are summarized. Additionally, the advantages and disadvantages
of the usual standard methods are reviewed. We compared electrochemical,
optical, and optochemical biosensors' properties and novel strategies for higher sensitivity
and selectivity.
Conclusion: The development of novel biosensors is required for the early diagnosis of
PD as sensitive, rapid, reliable, and cost-effective systems.
