On the front cover of Issue 21 Hatice Altug et al. demonstrate the first example of a large-scale plasmonic microarray with over one million sensors on single microscope slide.

Large-scale plasmonic microarrays for label-free high-throughput screening

The inside front cover highlights the review from Jurgen Popp on droplet-based microfluidic systems in Raman and SERS.

Droplet formation via flow-through microdevices in Raman and surface enhanced Raman spectroscopy—concepts and applications
Anne März, Thomas Henkel, Dana Cialla, Michael Schmitt and Jürgen Popp

And on the back cover is work from Piotr Garstecki et al.  showing their results on the speed of individual droplets in microfluidic channels – revealing quite a complex landscape of functional dependencies.

Speed of flow of individual droplets in microfluidic channels as a function of the capillary number, volume of droplets and contrast of viscosities
