Novel Applications of Nanotechnology in Diagnosis and Treatment of Neurological Disorders
Main Article Content
Abstract
The prevalence of neurological disorders with unknown causes is rising, includes well-researched conditions like Parkinson's, Alzheimer's, multiple sclerosis, Schizophrenia, cerebrovascular diseases and stroke. Consequently, focus has shifted to creating novel and efficient drug delivery devices that can transport drugs and have good brain bioavailability by Nano neurotechnology. Some of these issues have recently shown encouraging remedies due to use of nanoparticles in medicine delivery. In the diagnosis and treatment of various illnesses with drug and/or imaging agent efficacy, cellular uptake and selective transport to target organs frequently arise. Due to the BBB, a densely packed layer of endothelial cells that blocks foreign chemicals from entering the brain, neurodegenerative illnesses pose significant problems. Engineered nanomaterials, which are particles between 1 and 100 nm in size, are offering intriguing biomedical tools that may be able to overcome these issues because of their physico-chemical characteristics and the potential for multi-functionalization, which allows conferring variety of properties simultaneously, including the capacity to pass the blood-brain barrier. This study focuses on the most advanced nanomaterials for neuroprotection, neuronal tissue regeneration, and diagnostic imaging of the most prevalent neurodegenerative illnesses. The range of nanotechnologies that are readily available enables the nanoscale material with properties most suited to the therapeutic difficulties presented by a specific CNS illness. Clinical neuroscience's use of nanotechnology will depend on our capacity to combine it with our expanding knowledge of the molecular causes of CNS disorder. Finally, new nanotechnological methods are explored.
