Nanoplasmonic pillars engineered for single exosome detection

LSPRi versus SPRi exosome detection (background subtracted).
LSPRi data (orange line) are from the green 4 × 4 subarray (5.8 μm2) of Fig 4 while the SPRi data (red line) are from a single sensor of the Biorad XPR36 SPRi system (250,000 μm2). In both experiments, an exosome concentration of 1 × 105 exosomes/ml was introduced. The data sets have been offset in time so that the introductions of analyte coincide.
