Cover image: Cellular force generation can be quantified by measuring the strain on the microsensor posts. Shown is a fluorescence micrograph of a cell attached to a microfabrication array of polymeric posts. Local contractile forces exerted by actin cytoskeleton (red) of the cell (nucleus, green) are measured by deflections of the posts (blue). See article by Tan et al.on pages 1484–1489.
