Characterization of in-flow signals at 100 μL/min. Normalized OA and LS trajectories of (a) water as the solvent for μB and CNPs as well as of (b) PBS as the buffer for the cell suspension exhibit no detected transit event over 10 s record time. Water-suspended (c) μB and (d) reveal OA and LS signals of transits of individual particles. Unnormalized histograms are shown Gaussian-shaped distribution over the entire 1 min measurement. Normalized OA-FCM trajectories of E. coli expressing (e) mKO or (f) mCherry in PBS reveal detectable in-flow signals following a Gaussian-shaped distribution in the associated histograms.
