Research Project

Topic: Low-cost detecting system for (bio-)sensing applications based on monolithic polymeric devices interfaced with tunable optical filters

The long-term goal of this project is to develop a compact, reliable, easy to fabricate and cheap system able to detect chemical and biological analytes, to be used in a wide range of biological and biomedical sensing applications (e.g. detection of chemical, biological poisoning agents, environmental monitoring, medical diagnostics, food monitoring).
The approach is based on the utilization of 1D Bragg structures (DBR mirrors), where a tunable optical filter changes its refractive properties when in contact with an analyte of interest and the change can be detected by means of measuring the reflection or transmission of a known light source. The solution proposed here makes use of organic materials used as light emitting/absorbing layer integrated with the Bragg structures. The light emission of an embedded optical polymer is tuned by the analyte-dependent optical behavior of the filters and reabsorbed by an integrated organic photodiode.

The proposed detecting system is a stand-alone sensing platform, composed of two main parts, a tunable light emitting device (TLED) and a light-detecting device. The TLED itself is composed of different parts: one Bragg stack or a tunable cavity, which provide increased sensitivity to an analyte and/or the environmental changes such as temperature, humidity, electric fields etc and a light emitting source fabricated on a transparent substrate. In a further embodiment a microfluidic channel could be integrated on one side of the stack, where an analyte in a fluid will again induce changes in the optical system.
