Abstract
This work aims at developing a new technique to precisely assemble nano-materials into micro- or even meso-scale devices. For example, our long-term goal is to use massively architected motor-molecules to build muscle-like actuators in which these molecules work in parallel to output large forces. As an important first step, we report here the successful development of a much improved shear-flow-enhanced self-assembly method over the baseline spontaneous assembly method in test tubes, More specifically, we have engineered special thiolated model molecules (bisdisulfide/C 28H 34O 4S 4) and demonstrated the nano-to-micro self-assembly through flow interface using thiol-gold bonding chemistry. Our method has produced gold/molecule aggregates as big as 50μm that are completely made of 30nm gold nanoparticles and 3nm model molecules.
