Z-scan optical method complements the Thioflavin T assay for investigation of anti-Alzheimer's impact of polyphenols.

Polyphenols are effective in eliminating amyloid-beta aggregations, the main hallmark of Alzheimer's disease. Various nano drugs and biomaterials based on polyphenolic compounds have been synthetized to treat or prevent Alzheimer's disease, and the main in-vitro approach to investigate the anti-Alzheimer's properties of materials, is the Thioflavin T assay. While useful it has drawbacks and in particular cannot always guarantee the accuracy of data, specifically in cases of polyphenolic compounds; thus, in this situation accurate results requires utilizing other assays along with Thioflavin T.
