The aim of my thesis is to further develop the centrifugal microfluidics device, created by students, who previously worked on this subject. I established my work on the literature and their theses.

My first object was getting to know the tools and methods in the Sensor laboratory of the Department of Electronics Technology, which I will use later on during my work. These are the CO2 laser machine; using a 3D printer; contact angle measurements; designing in CorelDRAW; creating the microfluidic disc; high-speed camera; built-in spin coater. The next goal was obtaining and treatment of bovine blood. After building up the measuring setup, I examined some parameters of the platforms, which can affect the propagation of the sample liquids. This was followed by optimization of the camera and conducting pilot measurements.

Another major goal of my thesis was to create a programmable centrifuge. Part of the tools I used to build this centrifuge were available in the Sensory laboratory of BME ETT, and I managed to obtain the rest of the tools needed.

Although microfluidics did not yet revolutionize science, it has a lot of potential for applications, which can lead to breakthrough. The lab-on-a-disc concept can offer a lot of user friendly, low cost and standalone Point of Care diagnostics devices in the future. This can lead to significant improvement not only in the general healthcare of developing countries, but also in the areas of intensive care and emergency services of developed countries. This is why the development of these platforms is so important.
