In this letter, small amount of beer [0.42-2.08% (v/v)] is employed to investigate the fibril inhibition kinetics of 1 mM L-Phenylalanine and L-Tyrosine (relevant to disease condition) using Fluorescence Lifetime imaging Microscopy (FLIM), Field Emission Scanning Electron Microscopy (FESEM) and High Resolution Transmission Electron Microscopic (HR-TEM) techniques. Our results indicate that 1.67 and 0.42% of beer is sufficient for effective breakdown of L-Phe and L-Tyr assemblies, respectively. Quantitative information about fibril inhibition is obtained from Fluorescence Correlation Spectroscopic (FCS) measurements. We have shown that the morphology of L-Phe changes to L-Tyr in presence of 2,2'-Bipyridine-3,3'-diol (BP(OH)(2)). (C) 2017 Elsevier B.V. All rights reserved.
