Optical Hybrid Sensors for in vitro Diagnostics in Medical Engineering, E-Health and environmental- and foodstuffs Analysis

Construction of the optical hybrid sensor. GRIN lenses and convex lenses will be attached to each other. A biochemical connecting assay will be used and the hybrid system attached to a microfluid discharge system.

In this project a prototype for a new, optical hybrid system, mainly for in vitro diagnostics, will be developed. In doing so, established technologies from optics, surface technology and biochemical analysis will be combined and finally, the principle applications of the optical hybrid system will be tested.

Optical microresonators and so-called GRIN Lenses (graded index lenses) will be used. The latter are characterized by their high numerical aperture and very low costs. Both of these technologies will be attached to the optical hybrid system with a special adhesive technique. This type of hybrid system is highly suitable for the ultrasensitive detection of minimal differences in optical characteristics.

The goal is a widely deployable, inexpensive and robust optical detection system for applications in in vitro diagnostics and sensor technology, e.g. for implantable sensor systems or bioanalytical sensors on endoscopes, but also for testing in environmental-, water- and foodstuffs analytics.
