The AFM-MicroRaman Unit combines two different techniques.
On the one hand, Raman Spectroscopy that provides chemical identification, and
on the other, Atomic Force Microscopy that allows the registration of the
surface topography of a sample at the nanometric scale.
Confocal Raman Microscopy Service
It combines a Raman spectrometer (Raman spectroscopy) and a
Confocal Microscope.
This microscope allows, through the Raman effect, to
identify and characterize in a non-destructive and non-contact way the chemical
structure of almost any compound, so that it is possible to identify particles
of the order of the micron in isolation.
The Raman effect occurs when monochromatic radiation
interacts with the material generating an inelastic scattering of light,
obtaining, in general, a very weak signal since only 1 of approximately 106-108
incident photons contribute to the resulting Raman signal. The interaction of
the incident radiation with matter produces changes at the atomic level that
are detected by the Raman microscope and, therefore, the Raman signal
constitutes a fingerprint of each sample giving unequivocal information about
its chemical composition and the structure of the material.
Atomic Force Microscopy Service (AFM)
It is a mechanical-optical instrument capable of detecting
atomic or molecular forces of the order of nanonewtons between a nanosized
diameter tip and a sample. In this way, by tracking the sample with a very
sharp point, we can continuously record the topography of its surface, thus
obtaining a 2D and 3D image of the surface with a resolution of nanometers
(10-9 m), as well as roughness data of simultaneously.
Atomic Force Microscopy + Raman-NTEGRA Service
This service integrates two techniques combined in a single
system, atomic force microscopy (AFM) with Raman spectroscopy and confocal
microscopy.
Simultaneous recording with nanometric precision of AFM
measurements and Raman mapping of the same sample area provide essential
complementary information on physical properties, topography, roughness
analysis (AFM) and chemical composition (Raman), in order to be able to study
the distribution of chemical properties with molecular resolution.
Applications
InVia Reflex Raman Microscope
It has applications in a wide range of fields:
Earth Sciences (Geochemistry) (identification of gems,
precious stones, inclusions in minerals, etc.), biology and life sciences
(identification of organelles and biomolecules), environment (determination of
contamination by metal complexes in soils, etc.), electronics companies, semiconductors,
pharmaceuticals, materials sciences (study of polymers, nanoparticles, thin
films, inorganic compounds, analysis of carbon compounds, carbon nanotubes,
graphene, graphite, etc. .), in fine arts and humanities (analysis of paintings
and pigments of historical works of art as an aid for an accurate restoration
or an authentication), in forensic science or scientific police (identification
of drugs and explosives), chemical and physical sciences. To get additional details, view here: atom microscopy
Atomic Force Microscope (AFM)
This technique has been essential in the development of
nanotechnology for the characterization and visualization of materials at
nanometric dimensions, with which it has applications in many scientific
fields:
Physics, materials science (paint companies, automobile
industry, etc.) , microelectronics, engineering, chemistry, thin layers
(surface roughness analysis), biology and medicine (obtaining three-dimensional
images of proteins, DNA, etc.).
AFM + Raman Ntegra Spectra Microscope
Due to the combination of two complementary techniques, it
has applications of great interest:
Biology and medicine (analysis of biological structures),
materials science (study of carbon materials, graphene, carbon nanotubes,
nanostructures), polymers, semiconductors, geochemistry ( characterization and
identification of inclusions in minerals).
