On the cover: chemical delivery without fluid flow over cells and vapour deposition of cross-linked fluoropolymer coatings

On the cover this month are two hot articles from Nicholas A. Melosh et al. and Malancha Gupta et al, and both articles are free to download for the next 6 weeks.

Nicholas Melosh’s article on the outside front cover depicts their method for controlled chemical delivery in microfluidic cell culture devices without fluid flow over the cells, thereby avoiding the problem of cell perturbation.

On the inside front cover, the image from Malancha Gupta highlights a vapour deposition method to line the surfaces of PDMS microfluidic devices with a cross-linked fluoropolymer barrier coating, which significantly increases the chemical compatibility of the devices.
