Lysozyme crystals obtained in situ on chip through (a) microbatch crystallization in a 48 µm channel, (b) counter diffusion in a 48 µm channel and (c) counter diffusion in a 140 µm channel. The thinner 48 µm channel resulted in a flattened crystal morphology. Tuning of the channel layer thickness is simply accomplished by selection of the adhesive layer thickness [layer 4, Fig. 1(a)]. |
