On the Way to Nanometer‐Sized Information of the Bacterial Surface by Tip‐Enhanced Raman Spectroscopy

Abstract

A straight tip: With tip-enhanced Raman spectroscopy (TERS), chemical and topographical information with nanometric resolution below the diffraction limit of soft biological samples such as bacteria can be gained simultaneously at short measuring times. This noninvasive technique opens new ways for the investigation of many problems in biology and biomedicine.
