Abstract
We discuss advances in ultrasensitive Raman-spectroscopic probing of various biosamples. Our approach is based on laser spectroscopy aided by plasmonic nanoantennas, as for example in tip-enhanced Raman spectroscopy. An additional enhancement in sensitivity and speed is obtained by employing quantum molecular coherence driven either by pump and Stokes pulse pair or a direct infrared drive field.
