Single‐molecule detection (SMD) has been a hot topic for decades due to its extensive implementation in biomedical, chemical, physical, and material sciences. The methods used for single‐molecule detection are generally variants of fluorescence and Raman spectroscopy, which employs plasmonic particles for hot‐spot generation upon illumination. The signal generated by molecules in the hot spot is strong but not directive, so,
