Acceleration of deposition of Aβ1−40 peptide on ultrasonically formed Aβ1−42 nucleus studied by wireless quartz-crystal-microbalance biosensor

► We discovered anomalously high deposition rate of Alzheimer's disease peptides. ► Aβ1−40 monomer accumulates on ultrasonically formed Aβ1−42 seeds. ► Homebuilt multichannel QCM was used for long-time deposition monitoring. ► Deposited structure is clearly oligomeric. ► Discovered deposition system can be used for the drug development.
