Towards Modern-Age Advanced Sensors for the Management of Neurodegenerative Disorders: Current Status, Challenges and Prospects

Neurodegenerative diseases (NDD) are progressive degenerative disorders of the neurological system with significant social impact worldwide. Their detection at the initial stage is necessary to provide proper therapeutic interventions. Biosensors have emerged as one of the next-generation tools for detecting and monitoring physiochemical changes associated with neurological disorders. This article discusses the current status and challenges of different state-of-the-art sensors which can detect NDD biomarkers. A brief overview of developing advanced biosensors with the help of nanotechnology integration, mainly polymer-based functional nanomaterials, has been mentioned as the prospect of these biosensors for NDD detection and management.
