Maskless photopatterning of cells in microfluidic devices/
… need, building upon previous design of a dynamic lithography system, a stop flow lithography system was implemented capable of patterning individual particles with a mean accuracy of 11.92 [mu]m and a standard deviation of 4.63 [mu]m. This was achieved by improving the tracking capability of the …
