Fluorescent Carbon Dots for Neurodegenerative Disorders

Neurodegenerative disorders such as Alzheimer’s, Parkinson’s, and Huntington’s diseases present complex pathophysiology and lack effective therapies, confronting growing global health challenges. Over the past few decades, nanomaterials have undergone an astonishing revolution in the research and scientific communities due to their remarkable properties and notable applications in energy, environment, agriculture, health, and the pharmaceutical sectors. Nanomaterials are currently gaining recognition for their significant consequences due to their several uses in health and wellbeing. A promising tool for the investigation and management of these conditions is fluorescent carbon dots (CDs), a family of nanomaterials with remarkable properties, including biocompatibility and versatility. This review explores the multifaceted applications of fluorescent carbon dots for various Neurodegenerative and miscellaneous neurodegenerative disorders. This includes types of CDs, precursors, methods of synthesis, quantum yield, and their specific uses. The exceptional properties of CDs make them useful tools for bioimaging, enabling the study of brain structure and tracking the course of disease. CDs offer potential as drug delivery vehicles and theranostic agents capable of crossing the BBB and targeting specific neuronal populations. This study aims to shed light on fluorescent CDs in the field of NDs, outlining creative approaches for the diagnosis, treatment, and monitoring of neurological disorders.
