Raman spectroscopy can be combined with optical confocal microscopy to generate a new analytic technique called Raman microscopy. Light microscopy has several advantages: it can be used to observe ...

Raman microscopy is an analytic technique which uses a standard optical microscope in combination with a Raman spectrometer to visualize samples under high magnification as well as performing Raman ...

Researchers have developed a label-free and non-invasive Raman spectroscopy approach that can acquire microscopic images of biological samples and identify a wide range of biomolecules with ...

There are obvious differences between cancerous cells and normal cells in morphology, chemical properties and mechanical properties. The detection of cytochemical and mechanical properties of tumor ...

Spectral resolution is the most important feature of a spectrometer. This parameter determines the maximum number of spectral peaks that can be achieved using the system. For example, in the case of a ...

A new instrument lets researchers use multiple laser beams and a microscope to trap and move cells and then analyze them in real-time with a sensitive analysis technique known as Raman spectroscopy. A ...

Graphene is a material that has a one-atom layer of carbon atoms with a thickness of only 335 pm. It can be modified using oxidization and functionalization. For example, graphene gains properties ...

Raman analysis works by shining a laser on a sample and detecting the inelastically scattered photons. The resulting Raman spectrum provides information about the molecular structure and composition ...

In confocal Raman microscopy, a Raman spectrometer is coupled to a standard optical microscope, which leads to a high magnification of the sample and subsequent Raman analysis. Combining Raman ...
