Nanotechnology provides the tools to develop novel biosensors with improved performance, including sensitivity and response time that can be readily integrated into diagnostic devices. We have developed a miniaturized cell analysis platform to advance microfluidic cell cultures by combining two complementary, label-free and non-invasive cell analysis(More)
A complementary cell analysis method has been developed to assess the dynamic interactions of tumor cells with resident tissue and immune cells using optical light scattering and impedance sensing to shed light on tumor cell behavior. The combination of electroanalytical and optical biosensing technologies integrated in a lab-on-a-chip allows for(More)
Solution-processed organic diodes based on bulk heterojunctions are attractive for large area photodetection. We report a general approach for fully spray-coated organic photodiodes with outstanding characteristics in comparison to bladed or spin-coated devices. Despite the high surface roughness and the less defined morphology of the spray-deposited(More)
Organic semiconductors are attractive for optical sensing applications due to the effortless processing on large active area of several cm(2), which is difficult to achieve with solid-state devices. However, compared to silicon photodiodes, sensitivity and dynamic behavior remain a major challenge with organic sensors. Here, we show that charge trapping(More)
We have developed a μ-fluidic biochip capable of monitoring in real-time cellular phenotype dynamics by non-invasively assessing cell viability and reproduction over long periods of time. The μ-fluidic biochip contains integrated organic photodiodes that continuously perform light scattering measurements of adherent cell populations. In the(More)
Rapid and specific rare cell detection for point-of-care testing requires an integration of the sample preparation for flow cytometry. To achieve such a challenging goal we have developed a magnetic flow cytometry technique which applies magnetophoresis to perform cell enrichment, focusing, and background elimination in a single step.
