Quantum Dots Application in Neurodegenerative Diseases

: Quantum dots (QDs) are nanoparticles (NPs) with electronic and optical properties such as emitting bright light fluorescence. They also carry specific characters photostability, high quantum yield, emission, size-turnable. Nowadays, a great interest is given to the extensive use of theranostic-NPs for sensing imaging, well drug delivery. Moreover, QDs may yield potential diagnosis treatment various central nervous system (CNS) diseases (e.g., Parkinson’s disease, Alzheimer’s multiple sclerosis). The blood-brain barrier (BBB) protects brain tissue. Only certain small molecules like water gases can cross BBB, whereas larger enter via receptors, but many drugs incapable passing barrier. A series advances have been achieved concerning using different NPs QDs) deliver CNS imaging. In this review, we discussed wide variety along their production, passive or active delivery therapeutic agents neurodegenerative diseases, image production.
