AbstractLive biotherapeutic products (LBPs) are emerging as powerful tools to modulate the microbiome using well-defined microbial communities. Yet, designing, manufacturing, and delivering LBPs remains challenging, in part due to a lack of technologies capable of analyzing LBPs as complete, spatially organized consortia. Conventional sequencing-based methods lack sensitivity and specificity and do not provide critical spatial information.

Abstract Metamaterials are composite structures whose extraordinary properties arise from a mesoscale organization of their constituents. Here, we introduce a different material class—viscosity metafluids. Specifically, we demonstrate that we can rapidly drive large viscosity oscillations in shear-thickened fluids using acoustic perturbations with kHz to MHz frequencies.
