Work from Yongfeng Mei, Fudan University, and colleagues on developing superelastic microsprings features on the front cover of Issue 13. The rolled Ti nanomembranes stretch predictably and proportionally due to the drag force in flowing water, and so are potentially useful as sensors in micro-/nano-electromechanical systems.

The back cover is courtesy of Samir M. Iqbal and coworkers, who have developed a solid micropore device to detect tumour cells. By pushing cells through the single micropore one at a time cells can be differentiated based on size, elasticity, viscosity and stiffness.

Also in this issue we have another of our acoustofluidics series which looks at perturbation methods for analysing acoustic streaming and the latest Research highlights article from Ali Khademhosseini.
