Took a look at the article; their conclusion is that a significant reduction of the Casimir force can be achieved using metal gratings, at relatively large separation distances (> 200 nm). Unfortunately this does not solve the problem of high nano-scale adhesion in MEMS devices, because that implies the state is in contact (which is ~1 nm separation, depending on how you define how the atoms of different surfaces "touch" each other). At these small contact distances, the adhesion forces do not reduce with the grating approach. However, using the gratings can slightly reduce the risk of a MEMS component from collapsing when at larger distances from an opposing surface. Essentially, the approach can a device that should not touch an opposing surface, but will not help a device that needs to touch an opposing surface (i.e. a MEMS RF Switch).
