Future Direction

Our DiaCHIP as innovative diagnostic device can be used to simultaneously detect antibodies for numerous diseases, requiring only a few drops of blood, thus allowing fast detection of an acute disease. We are developing a next generation diagnostic technology and hope to contribute positively to public health. One big advantage of the DiaCHIP ist the possibility to make this new technique of simultaneous disease diagnostic accessible to everyone in a cheap and fast way. Another advantage is the provision of simultaneous disease diagnostics that is, thanks to the DiaCHIP, accessible to everyone in a cheap and fast way. During our project we could show, that it building a measurement device can be done in a low-cost manner. Therefore it would be possible for hospitals or doctors all around the world to afford a measurement device. The biological part of our project involving the the DNA template chip, cell free expression and hence production of a protein chip to test for diseases is also easily manageable with on-site trained medical staff.

Our project keeps many possible applications at hand if we will be able to further optimize the cell-free expression system and the specific binding to the surface for generating a protein chip. Investigating a quantification method may allow medical professionals to make a conclusion concerning the state of vaccination of a patient and might render some additional immunizations unnecessary.

It could provide a tool for accurate analysis of the antibody titer of a person thus helping to keep up a constant protection against many diseases.

With further work on the DiaCHIP it could also be possible to distinguish between vaccines from different manufactures. Is there any advantage?

The DiaChip could also be used for pre-pregnancy test, where evaluation of the antibody titers against certain diseases like e.g. rubella or whooping cough is crucial. Here the safety of the unborn child relies on the health status of the mother, therefore exact knowlegde of possibly required immunizations before a pregnancy could be of major importance. With our chip this would be a matter of one test and half an hour (?) before the vaccination status is determined and the required vaccinations can be started.

One more possible application of the DiaChip is the use of it to pre-test blood from blood donations. For this test only a small amount of blood it needed and in approximately 30 minutes all necessary examination could be done in just one test. This would simplify the testing of donated blood and minimize the time and costs involved in this.

Beyond fields of application in clinics as such, the suggested method of cell-free expression would simplify the preparation of protein microarrays on demand as no purification of protein is necessary anymore. This could be a major advantage in scientific research as handling and storage of protein arrays still poses some challenges. With our system of cell-free expression the production of protein arrays could provide an easy method to work with freshly produced protein chips. Such a cell-free produced microarray could be for example used to scan for epitopes.
