Highlighted on the front cover is work by John deMello and colleagues, applying enhanced temperatures for micro continuous-flow synthesis of nanoparticles with excellent reaction control:
A stable droplet reactor for high temperature nanocrystal synthesis
A. M. Nightingale, S. H. Krishnadasan, D. Berhanu, X. Niu, C. Drury, R. McIntyre, E. Valsami-Jones and J. C. deMello
On the inside front cover we have work from Miles Padgett and Roberto Di Leonardo. In their critical review they provide a comprehensive overview of optical tweezers and holographic optical tweezers for lab-on-a-chip applications:
Holographic optical tweezers and their relevance to lab on chip devices
Miles Padgett and Roberto Di Leonardo
The issue also includes HOT articles on observations of the positional dependence of particles in microfludic impedance cytometry, a great new method for fast, cheap PDMS patterning using direct UV lithography and on the back cover we highlight a microfluidic paper-based chemiluminescence biosensor for simultaneous glucose and uric acid developed by Jinghua Yu et al.
