Abstract

SEM images after every step of the reaction: (a) streptavidin self-assembly on the FBAR on FBAR, (b) the prepared AuNPs-MUC1 ampters chelates, (c) few AuNPs-MUC1 ampters chelates captured by streptavidin without target MUC1, and (d) a large amount of AuNPs-MUC1 ampters chelates captured by streptavidin with target MUC1.
