'The Design of a Ferrofluid Magnetic Pipette,'
MSEE Thesis, University of Washington, Department of Electrical Engineering, June 1995.
Abstract
New technological demands have motivated the search for methods of
handling volumes of liquid smaller than 0.2 microliters. This thesis
project addresses the problem of handling submicroliter liquid volumes
smaller than 0.1 microliter.
We have implemented a pipet utilizing ferrofluidics to handle
submicroliter volumes. The slug of ferrofluid acts as the plunger as in
a conventional mechanical pipet. To sample a small amount of fluid, the
electromagnets are used to actuate a position change of the ferrofluid
similar to conventional pipets which aspirate and dispense liquids by
changing the position of the plunger. Mathematical models used to
estimate the performance of the pipet are presented in Chapter 2. These
models form the theoretical basis of ferrofluidics and magnetism as it
applies to the ferrofluid-magnetic pipet. Experimentally measured
performance data and the comparison of the data with the model's
prediction are also presented.
