Zusammenfassung:Single molecules are elusive and often produce misleading signals. Surface‐enhanced Raman spectroscopy (SERS) is one of the few techniques capable of verifying the presence of single molecules. To achieve the goal, the bianalyte proof is favored by researchers as it relies on the statistical analysis of thousands of spectra, rather than the fluctuating signals observed at limited spots. Since the hotspot of SERS is extremely small (
