A. The lab on a chip includes a bottom fluidic layer (red) with a gradient generating network,
a cell seeding network, and observation chamber; a top layer (blue) with valves to control the
flow of channels in the bottom layer, and a glass lid with micro-wells (darker red) where neuronal
cell samples are placed. B. A 3D schematic image of the chip assembly.

Will speed studies of brain cells
Johns Hopkins researchers from the Whiting School of Engineering and the School of Medicine have devised a micro-scale tool – a lab on a chip – designed to mimic the chemical complexities of the brain. [Read more…]
