The growing research in bioengineering calls for in vitro, non-invasive nanoscale characterization of biological macromolecules. However, current imaging tools often use ionizing radiation under high vacuum and/or cold temperature, conditions that are far from the native biological environment. We resolved this challenge by combining nano- Fourier transform infrared spectroscopy (nano-FTIR) with graphene-capped liquid cells that allow us to perform infrared spectroscopy of proteins in their natural liquid e
