Fig. 6. Sensitivity of the proposed 3D photonic crystal-based biosensor with real serum samples including H1N1 virus particles. (a) Fluorescence captured images using fluorescence microscope and home-made setup with a smartphone camera, respectively. (b) The measured relative fluorescence intensity during virus detection in the ideal sample (red) and real sample (green) with different concentrations of influenza A (H1N1) virus. The scale bars in the images of the microscope and home-made setup are 20 μm and 3 mm, respectively.
