Cryoporometry in Femtoliter Volumes by Confocal Raman Spectroscopy [PDF]

Langmuir, 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 ...

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

Biophysical 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.

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

Foods, 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 ...

Raman spectroscopic detection of interleukin-10 and angiotensin converting enzyme

Journal of the European Optical Society-Rapid Publications, 2021
In this report we present a confocal Raman system to identify the unique spectral features of two proteins, Interleukin-10 and Angiotensin Converting Enzyme. Characteristic Raman spectra were successfully acquired and identified for the first time to our
