Systems engineering is an effective tool in modeling many different types of processes.
It can be used to simplify complex biological systems, for example, by defining their sub-
systems, requirements, constraints, and the relationship between them. In the following report, a
systems-level approach is used to analyze a microfluidic particle steering device. The device
functions by sensing the position of a fluorescently tagged particle within a microfluidic channel
and comparing it to a desired location that is entered by the researcher. This information is
analyzed by a control algorithm that processes the error between the current and wanted position
of the particle. Then a computer sends output to a steering mechanism that will guide the
particles to the proper location. This process is repeated until the particle has been steered along
an entire path.
