Raman Spectroscopy of Biological Tissue for Application in Optical Diagnosis of Malignancy [PDF]

open access: yes, 2010
The use of Raman spectroscopy in the detection and classification of malignancy within the human larynx and lymph nodes of the head and neck has been evaluated. Currently histopathology is considered the diagnostic gold standard.

Noise Sources and Requirements for Confocal Raman Spectrometers in Biosensor Applications

open access: yesSensors, 2021
Raman spectroscopy probes the biochemical composition of samples in a non-destructive, non-invasive and label-free fashion yielding specific information on a molecular level. Nevertheless, the Raman effect is very weak. The detection of all inelastically

Cryoporometry in Femtoliter Volumes by Confocal Raman Spectroscopy [PDF]

open access: yesLangmuir, 2019
The properties of porous material are largely dependent on the size, shape, and connectivity of the pores. Here, we present a method based on confocal Raman spectroscopy to quantify porosity using a cryoporometric approach. We show that the phase transition of water imbibed in porous silica can be accurately determined using two different, but ...

Applicability of Confocal Raman Microscopy to Observe Microstructural Modifications of Cream Cheeses as Influenced by Freezing

open access: yesFoods, 2020
Confocal Raman microscopy is a promising technique to derive information about microstructure, with minimal sample disruption. Raman emission bands are highly specific to molecular structure and with Raman spectroscopy it is thus possible to observe ...

Formation mechanisms of sub-micron pharmaceutical composite particles derived from far- and near-field Raman microscopy

open access: yesJournal of Pharmaceutical Analysis, 2021
Surface enhanced Raman spectroscopy (SERS) and confocal Raman microscopy are applied to investigate the structure and the molecular arrangement of sub-micron furosemide and polyvinylpyrrolidone (furosemide/PVP) particles produced by spray flash ...

Combined In Vivo Confocal Raman Spectroscopy and Confocal Microscopy of Human Skin [PDF]

open access: yesBiophysical Journal, 2003
In vivo confocal Raman spectroscopy is a noninvasive optical method to obtain detailed information about the molecular composition of the skin with high spatial resolution. In vivo confocal scanning laser microscopy is an imaging modality that provides optical sections of the skin without physically dissecting the tissue.
