The cell canary system will combine live bio-engineered cells with on-chip MEMS hardware. It will function by monitoring the response of many live cells to an external environment. Each cell, or cell colony, will be bio- engineered to fluoresce in response to a specific external pathogen. The fluorescence will occur through a FRET interaction with a quantum dot that labels a component of the pathway. If the cell or cell ...
Ion transport is critical to improving the performance of conjugated polymer actuators, particularly their strain and speed. We present a novel device that allows us to measure ion transport directly and independently from electron transport in PPy films. The device geometry makes the path for ions much longer than that for electrons, ensuring that ion transport is the rate- limiting step. In addition, ion transport is visualized directly though the ...
