Abstract

The kinetic process of amyloid ! (A!42) fibrillation, critical event evoking Alzheimer disease, is investigated by a label-free biophotonic method. Utilizing gold nanoplasmonic particles (GNPs) as local light sources, the dynamic process of A! fibrillation was monitored by tracking random movement of GNPs. As fibrillation progressed, the movement was more restrictedly due to the growth of neighbor A! 42. Since GNPs do not have photo-bleaching and they can be used as optical antennas in living cells, this approach overcomes the limitation of current methods and broaden the quantitative analysis to probe in-situ and in-vivo monitoring of cellular kinetic events.
