Combination of nanogap method and machine learning. (a)–(c) Combination of recognition tunnel and machine learning. Reproduced with permission from ref (8). Copyright 2014 Springer Nature. (a) Principle diagram of recognition tunnel. (b) Glycine tunneling current vs time waveform. (c) Identification accuracy for Leu and methylated Gly obtained by analysis using a SVM. Red indicates methylated glycine data points, and green indicates Leu data points. The features are obtained by FFT of each pulse. (d)–(f) Principle diagram of a bare nanogap electrode.
