Biosensors in Parkinson's disease

Area of Science:

• Biomedical Engineering
• Neuroscience
• Analytical Chemistry

Background:

• Parkinson's disease (PD) is a progressive neurodegenerative disorder affecting over six million people globally, significantly impacting quality of life.
• Current diagnostic methods for PD, relying on clinical evaluation and routine tests, suffer from limitations like low sensitivity, selectivity, and high costs.
• The need for advanced, sensitive, and accessible diagnostic tools for Parkinson's disease is critical.

Purpose of the Study:

• To review the latest advancements in biosensor technology for the diagnosis of Parkinson's disease.
• To highlight the potential of electrochemical and optical biosensors as novel diagnostic platforms for PD.
• To discuss the advantages of biosensors over conventional diagnostic methods for PD.

Main Methods:

• Review of recent scientific literature on biosensors for Parkinson's disease diagnosis.
• Focus on electrochemical biosensors utilizing nanomaterials like gold nanoparticles (AuNPs), quantum dots (QDs), and carbon nanotubes (CNTs).
• Evaluation of optical biosensor technologies for PD detection.

Main Results:

• Biosensor technology presents a promising new avenue for reliable, repeatable, and multidimensional identification of PD.
• Electrochemical biosensors, enhanced by novel materials, are at the forefront of progress in PD diagnostics.
• Biosensing systems offer potential for improved PD treatment and monitoring.

Conclusions:

• Biosensors represent a significant advancement in the diagnosis of Parkinson's disease, offering improved sensitivity and patient comfort.
