Microfluidic chemostat system modified from Jeff Hasty's group
Design
In order to increase the number of nanotube transfer events we observe in each experiment, we modified the microfluidic device from Jeff Hasty's recent paper. Here the geometry of the microfluidic device is shown. It's a design where cells are grown in chambers of 40 micron x 50 micron x 1 micron, where two flows of medium are fed at the top and bottom of the squares. This way, the cells are constantly fed, grown exponentially into a single layer in the chamber, and extra cells are carried away by the flow. In the image, the channels for the medium flow are lined horizontally, and the "train" of squares correspond to our chambers. The bigger squares are our 40 by 50 micron chambers, and the smaller squares are the separating columns.
