Different wet, unstained biological samples were imaged at 55 nm spatial resolution by the use of scanning transmission X-ray microscope (STXM). The microscope has measured the modulation transfer function which agrees well with theoretical calculations. The chemical composition of the sample is localized by x-ray energy variation in which the beam is focused to one spot. Another technique is X-ray absorption near edge structure which is chemically sensitive thereby acting as a contrast mechanism for organic system imaging. Due to its sensitivity, it can be easily applied for chemical reaction investigations.
