Imaging ToF-SIMS and synchrotron-based FT-IR microspectroscopic studies of prostate cancer cell lines

Imaging ToF-SIMS and synchrotron-based Fourier transform infrared (SR-FT-IR) microspectroscopy have been used to obtain chemical information from individual cells derived from human prostate cancer (CaP). ToF-SIMS imaging of molecular signals characteristic of membrane bound phospholipids are used to elucidate different fracture planes within individual freezefractured CaP cells. The localisati...

Structural Analysis of Hirudin Using FT-IR and FT-Raman Spectroscopic Techniques

FT-IR and FT-Raman spectra of hirudin have been recorded from the native solid hirudin. The conformation of the molecule has been discussed on the basis of IR and Raman data. It has been concluded that hirudin molecule has a mixed a-helix and random coil conformation.

Recovery of absorption spectra from Fourier transform infrared (FT-IR) microspectroscopic measurements of intact spheres.

An infrared spectrum recorded from a microscopic sample depends on spectral properties of the constituent material as well as on morphology. Many samples or domains within heterogeneous materials can be idealized as spheres, in which both scattering and absorption from the three-dimensional shape affect the recorded spectrum. Spectra recorded from such objects may be altered to such an extent t...

What Is an Ft-ir and an Ft-ir Spectrometer?

An FT-IR Spectrometer is an instrument which acquires broadband NIR to FIR spectra. Unlike a dispersive instrument, i.e. grating monochromator or spectrograph, an FT-IR Spectrometer collects all wavelengths simultaneously. This feature, called the Multiplex or Felgett Advantage, is discussed in detail on page 3. FT-IR Spectrometers are often simply called FT-IRs. But for the purists, an FT-IR (...
