🚀 Just like atoms, metasurfaces can be pushed or pulled by light. At @QuidantL, we demonstrate attractive and repulsive optical forces using engineered meta-atoms. Check out nature.com/articles/s41467-0… in @NatureComms by @AdeelAfridi10 and @BrunoMelo1234! @ETH_en #Nanophotonics

In the second we demonstrate a platform for multi-parametric analysis of aptamer sequence design with high temporal resolution. We show using FRET and droplets that aptamer-serotonin binding is a two step process and can follow different pathways. pubs.acs.org/doi/full/10.102…
