||A lab on chip is a concept that in recent years became a very popular alternative
to traditional laboratories. A digital micro
fluidic biochip is one of the devices
that are strictly connected to the lab on chip concept.
fluidic biochips are very small devices capable of replacing conventional laboratories by performing all the necessary biochemical functions using
droplets with volumes as low as picolitres.
A digital biochip is composed of a two-dimensional array of identical cells, together with reservoirs for storing the substances. Each cell consists of several
control electrodes, used for moving the droplets on the array. This is done by
applying voltages to required electrodes.
Any biochemical application can be decomposed into a series of basic micro
fluidic operations (e.g., creating a droplet with a precise volume, mixing two
droplets, diluting a droplet with a buer solution). Performing such operations requires transporting droplets on the array according to a certain pattern,
therefore a sequence of electrodes activation is required.
Given a biochemical application in the form of a set of micro
together with the activated electrodes at each moment, a simulator provides
a graphical representation of the droplets movement on the array, either as a
realistic model showing the exact droplet movement or as a simplified model,
with modules representing the operations. The simulator also captures specific
situations that may appear during the execution of the application, like an in-correct execution of operations.
The simulator can provide useful information on the efficiency of the current
design, before an actual chip goes into production.
This thesis provides brief theoretical information about the micro
and the biochips. Furthermore, a simulator concept is provided, followed by
the detailed information on its design and implementation, including two aforementioned models (simplified and realistic) and faults simulation. Finally, a
technical documentation on the tool itself is provided, followed by a list of possible future extensions.
