− | <h1>Building our own device</h1>
| |
− | <p>The original measuring device we were using in collaboration with AG Roth is a really expensive machine based on rather simple physics. Therefore, we decided to build our own device in a cost-efficient variant. We performed reliable measurements with it and provide a building plan making label-free proteinarray analysis available for every future iGEM team. </p>

− | <h1>Communicating science</h1>
| |
− | <p>Fast and reliable disease diagnostic is a problem of public interest. For this reason we wanted to know what people think about the idea of the DiaCHIP. Although the DiaCHIP is concerned to synthetic biology, which makes people feel rather uncomfortable according to a survey by Leopoldina (national academy of science), we obtained a lot of positive feedback. </p>

| |
− | <p>In order to optimize the DiaCHIP for future applications, we modelled the process of cell-free expression and diffusion over time. Making use of xxx parameters and xxx ordinary differential equations, we computed the size of the resulting antigen spots and identified the factors limiting cell-free expression in the DiaCHIP. </p>

| |
− | <p>One of the most notable results we obtained was the detection of anti-tetanus antibodies in human blood serum. Using the DiaCHIP, we were able to distinguish serum samples of a person taken before vaccination and three weeks later. As expected, antibody binding events were shown after vaccination, whereas there was no signal before. </p>

− | The DiaCHIP is an innovative tool to simultaneously differentially detect antibodies present in blood sera that correspond to infectious diseases. It may greatly simplify broad band screenings, detection of autoimmune diseases and the determination of vaccination status. Essential for our project idea is the combination of on-demand protein synthesis directly in the diagnostic device, that is using a novel and label-free detection system, so simple that it can easily be rebuild and utilized by future iGEM teams.

− | As the DiaCHIP relies on antibody-antigen interactions, the antigens first have to be synthesized and immobilized inside the device. Given that the whole device is a microfluidic system, it was most convenient to do this directly in the flow-chamber, where detection will finally take place.
| + | |
− | The flow-chamber consists of two glass surfaces separated by a gap that can be flushed with liquids. On the one surface DNA molecules, which code for the respective antigens. By flushing a cell-free expression mix into the chamber, the respective antigens are transcribed and translated on-demand. Proteins then diffuse until reaching the second surface that specifically captures the proteins encoded by the immobilized DNA. After several washing steps to remove remaining expression-mix the flow-chamber is coated with the immobilized antigens and ready for detection.

− | With the iRIf (Abkürzung) system it is possible to record small changes in layer thickness. The binding of an antibody, present in the blood serum flushed through the chamber, to the according antigen increases the local thickness of the protein surface so that interaction events can be measured label-free and in real-time via the change of the optical properties at this spot.
