Nanotechnology and nanomedicine have significantly advanced diagnostics and treatments for life-threatening and disabling diseases. Nanoparticle properties and characteristics are the most impactful force in medicine. Their size, shape, charge, surface area, solubility, and many other properties are substantial in diagnosing and treating. Their size and surface area are inversely proportional to each other. In other words, the smaller the size, the higher the surface area. Thus, their dose is less, better penetration, solubility, bioavailability, point-specific location, fewer side effects, and less toxicity.

Nanoparticles have opened new potential for diagnosis and treatment of neurodegenerative disorders. Neurodegenerative disorders affect the central nervous system (CNS) and disrupt communication between neurons vital for motor, sensory, and cognitive processes. The usage of Nanotheranostic has shown advances in the discovery of potential methods that can reduce inflammation, aggregates, and reactive oxygen species (ROS). Lastly, it is expected that there will be more usage of nanoparticles to detect and treat neurodegenerative disorders like Alzheimer’s and Parkinson’s.
