Abstract
The invention relates to color-changing eye drops for early screening Alzheimer's disease and an application thereof. The color-changing eye drop for early screening Alzheimer's disease comprises 1 pg/ml to 10 ng/ml of Aβ42 aptamer-gold nanoparticles (AuNPs) and a pharmaceutically acceptable carrier or vehicle thereof, which can be used to mix with a tear sample of a test subject to analyze a color change of the color-changing eye drop for determining the concentration proportion of Aβ40:Aβ42 contained in the tear sample of the test subject.
