Raman microscopy is useful for molecular imaging and analysis of biological specimens. Here, we used alkyne containing a carbon-carbon triple bond as a Raman tag for observing small molecules in live cells. Alkyne tags can maintain original properties of target molecules with providing high chemical specificity owing to its distinct peak in a Raman-silent window of biomolecules. For demonstrations, alkyne-tagged thymidine and coenzyme Q analogue in live cells were visualized with high-spatial resolution. We extended the application of alkyne-tag imaging to visualize cell organelles and specific lipid components in artificial monolayer membranes.
