Fig. 5. Influenza A (H1N1) virus detection with the proposed biosensor and home-made setup. (a) Fluorescence images captured by the smartphone camera with different concentrations of influenza A (H1N1) virus (from 20 ng mL−1 to 200 μg mL−1) on PC and glass, respectively. (b) Scheme of the proposed low-cost portable home-made setup for influenza A (H1N1) virus detection and image of the fabricated result. (c) Quantitative analysis of fluorescence intensities with different concentrations of influenza A (H1N1) virus on PC (black) and glass (white). The scale bars in the images of PC and glass are 2 mm and 5 mm, respectively.
