摘 要:Ideal single-cell viscometer has remained unachieved,leaving a gap in current palette of single-cell *** of single-cell viscosity could contribute to our knowledge of fundamental biological processes,e.g.,mass diffusion,biochemical interaction,and cellular responses to many diseases and *** advances have been made to this end,existing methods generally suffer from limitations,e.g.,low spatiotemporal ***,we describe a high spatiotemporal iontronic single-cell viscometer that operates upon a patch clamp integrated with double-barreled nanopores separated by a septum of ca.32 *** system enables reversible electroosmotic manipulation of the adjacent small fluid bridging two nanopores,the viscous alternation of which could be sensitively monitored by the ionic *** practical cellular studies,significantly,our findings reveal not only the less deviated medium viscosities than those of lysosomes and mitochondria but also the highest viscosities in the near-nuclear region than those of mitochondrion-dense and lysosome-dense *** work has provided an accessible single-cell viscometer and enriched the armory of single-cell nanotools.
