Combined/hybrid systems literature
Product note: SCA - diamond composite analysis
Renishaw’s structural and chemical analyser unites two well-established technologies, scanning electron microscopy (SEM) and Raman spectroscopy, resulting in a powerful new technique which allows morphological, elemental, chemical, physical, and electronic analysis without moving the sample between instruments.
Application note: A study of single-wall carbon nanotubes using Renishaw's structural and chemical analyser for scanning electron microscopy
Electron imaging and Raman spectroscopy are established techniques for viewing and analysing carbon nanotubes. Performing these two techniques usually requires the sample being transferred between a scanning electron microscope (SEM) and a Raman spectrometer. This application note illustrates the advantages of Renishaw’s structural and chemical analyser (SCA) for simultaneous secondary electron imaging and Raman spectroscopy of single-wall carbon nanotubes (SWNTs).
SCA oxidation application note - cultural heritage
SEM-SCA analysis helps in the preservation of a corroding bronze statue of the Roman god Ares from the ancient city of Zeugma in Turkey.
Inverted microscopes for inVia
Product note: Enabling you to view large samples or biological specimens from below, rather than above, Renishaw's inVia Raman spectrometers can be equipped with inverted microscopes instead of, or in addition to, the standard upright microscopes.
Renishaw Raman-AFM/TERS solutions
Product note - Combined Raman/AFM (atomic force microscope) systems are excellent for characterising the properties of materials at sub-micrometre, and potentially nanometre, scales.Tip-enhanced Raman scattering (TERS) provides chemical imaging at the nanometre scale, enabling you to take your research to a whole new level.
We have also produced a range of application examples, including the following.

AFM and 3D Raman imaging of glioma cells
Reveal detailed and complementary information on the composition of glioma cells by atomic force microscopy (AFM) and inVia 3D Raman imaging. The AFM topograph—with nanometre-range spatial resolution—clearly identify cellular structures, but not their chemical compositions. By comparing and correlating AFM topographs with the additional chemical information from 3D Raman images, researchers can gain a better understanding of the cell.
See sub-diffraction limit graphene features using tip enhanced Raman spectroscopy
Reveal highly detailed graphene information by performing tip enhanced Raman spectroscopy (TERS) using inVia combined with an AFM. TERS uses a special plasmonic tip to increase the local electric field at the sample which, in turn, increases the Raman intensity.
TERS of a malachite green monolayer
Analyse minute sample volumes and weak Raman scatterers using inVia and TERS. Tip enhanced Raman spectroscopy (TERS) uses a special plasmonic tip to increase the electric field at the sample which, in turn, increases the Raman intensity. These tips are very small, with diameters on the order of 10 nm to 100 nm, and are held in contact with the sample using a scanning probe microscope (SPM) or atomic force microscope (AFM).
