Detection of three grades of Ade and SCC tissue lysates. (a) Change in absorption intensities for three different tissue lysates (normal, Ade and SCC) using the ssDNA-AuNPs-GO sensor array (NP1-NP6). (b) Canonical score plot of the absorbance patterns as obtained from LDA against the three grades of Ade patients. (c) LDA score plot derived from the absorbance changes for the three grades of SCC patients. (d) Heat map derived from absorbance response pattern for different grades of Ade and SCC patients.
