Investigation of Diffusion Characteristics through Microfluidic Channels for Passive Drug Delivery Applications

Figure 1

Leaf, Straight, and Snake (left to right) microchannel designs for a range of diffusive characteristics. All channels are 50 μm wide and 50 μm tall. Device length () 2.5 cm. Width () 1.5 cm. Reservoir length () 0.5 cm. Reservoir width () 0.75 cm. Reservoir height was kept constant at 3 mm. Representative devices for each design are shown below the corresponding graphic (scale bar represents 1 cm).
