a Schematic view of the stopped flow lithography (SFL) microfluidic device developed by Doyle et al. b Polymerisation is prevented at the interface of the reactor walls due to oxygen inhibition. This prevents any fouling and enables the particles to be washed downstream with resumed flow, c range of PEG-DA particles synthesised (insets show transparency masks used for each shape, scale bars are 10 μm), the height is determined by the microfluidic channel.
