Micro-scale Instruments Applied to a Bovine Nuclear Transfer System [article]

Andrew Leif Clow, University Of Canterbury
Manual handling of biological cells is routine in most laboratories. This is gradually changing with the development of robotic cell handling systems, and micro-scale lab-on-chip devices.  ...  Many miniaturised lab-on-chip systems rely on cell transportation. One illustration in the baseline procedure is the on-chip transport of cells to the cell fusion device.  ...  Microtool design differed from many lab-on-chip devices because the operation of these other devices concern fluids rather than particulates or cells.  ...
