Abstract
The Scanning Transmission soft X-ray Microscope (STXM) at the X1A beamline at the National Synchrotron Light Source, Brookhaven National Library has been used to image wet biological samples using the natural absorption differences between carbon and water in the water window. The step-like jumps in the absorption of soft x-rays by materials as a function of energy have been used for elemental mapping. The paper examines the x-ray absorption fine structure spectra at the carbon absorption edge from DNA and bovine serum albumin taken using the STXM. Differences between the spectra of these two biologically important molecules can be used to distinguish DNA and proteins.
