Extended Data Fig. 3: Microgauge monolayers before and after melting.
From: Upconverting microgauges reveal intraluminal force dynamics in vivo
a, An SEM micrograph of microgauge monolayers on hydrophilized silicon. Scale bar, 50 um. b, The same region after melting (30 minutes), with a higher resolution inset to show nanoparticles distributed evenly across the surface. Scale bars, 10 um, 500 nm (inset). Clusters like the one shown in the bottom left of the inset were easily visible from confocal UCL maps and were avoided during the calibration.
