The fabricated channel structures can be as complex as electron beam lithography can make them. Working channels have the minimum width and depth of 4 \u00b5m x 4 \u00b5m.\n\nThe microfluidics is controlled with Fluigent MFCS, enabling pressures up to 345 mbar. Liquid flow rates range from 40 pl/s up to 1.2 nl/s. Objects in such small channels still run with channel speeds of tens of micrometers or even millimeters per second. With a T-junction structure, droplets of water/oil can be formed and controlled.\n\nThe system is coupled with a Raman microscope, enabling at least the detection of carbon nanotubes inside the droplets. However, due to high channel speeds, the droplets need to be stationary to get good measurements. Carbon nanotubes also tend to form bundles and finally block the channels. Raman spectrum of multiple nanotubes was observed.\n\nThe stage is now set for further and more complex measurements.
