(A) Correlation (R² = 0.9965) between the LSPR spectral centroid shift and the concentration of target strand, the rs242557 tau gene, over the range of 0 to 2 μM. Insert: linearity over the concentration range up to four orders of magnitude. (B) The LSPR extinction spectra of SA-GNU in PBS and in 10-fold diluted serum as measured by the WLSI-based spectrometer.
