A neurodegenerative condition called Alzheimer's disease (AD) is brought on by the buildup of beta-amyloid plaques in the brain. As of right now, AD has no known cure. The only thing the medications on the market can do is slow their development. Nonetheless, nanotechnology has demonstrated its superiority in its application in medicine. It has great promise for AD therapy, mostly in diagnosing the ailment and offering a different treatment method. Penetrating and bypassing the blood-brain barrier (BBB) increases the effectiveness of drug delivery. The most recent advancements in AD diagnosis using nanotechnology based on nanoparticles with optical sensing, electrochemical sensing, and imaging approaches are summarised in this study. When treating AD, nanocarriers help deliver the targeted medication. Since one of the newest and most active treatments for AD is nanomedicines, the main goal of this review is to comprehend the sophisticated application of nanocarriers for targeted drug delivery in AD treatment.
