Abstract: The dream of having a device in the palm of our hand able to deliver an instant diagnostics of our health status could become a reality very soon. Silicon photonic biosensors have revealed themselves as the most promise candidates for achieving truly point-of-care devices for healthcare diagnostics, which could be employed in any place and any time in a user friendly way. Advantages as miniaturization, sensitivities clinically relevant, robustness, reliability, potential for multiplexing and mass production at low cost can be offered by these silicon photonics-based biosensors, opening the door to a general access to acute diagnostics by the underdeveloped countries [1]. This dream strongly drives the research done by the Nanobiosensors and Bioanalytical Applications Group at the Research Centre on Nanoscience and Nanotechnology (CIN2-CSIC) in Barcelona (Spain), a highly interdisciplinary and motivated group, which is developing point-of-care devices based on a novel inteferometric configuration using silicon photonics
