Micron-Scale Biological Devices

July25

The advent of micro-fluidics has been a boon to research in biology and medicine. Already many such devices exist in the commercial domain reducing what were a plethora of flasks, transfer processes and reactions at the macroscopic scale (even with a few micro-liters) to something that works in nano- and femto liter volumes.
We are using the relatively simpler process of soft-lithography by optimizing patterns using phot

The bacterial mother machine devlice (with high autofluorescence) and the assembly of the entire device (Manasi Gangan)

oresist that can be exposed to UV and post-baking used for building channels, flows and growth-chambers for cells.
We have reproduced the ‘mother-machine’ for bacterial cells described first by Wang et al. from Suckjoon Jun’s lab.

We are currently testing the results and developing some image analysis tools to extract meaningful numbers from the device.
