In vivo evaluation of the skin penetration and efficacy of ceramide nanomulsions by confocal Raman spectroscopy

open access: yesJournal of Raman Spectroscopy, 2023
Ceramide NP (Cer‐NP) has favorable effects in treating dry skin and barrier damage; nevertheless, their efficacy is hindered by a relatively low skin permeability.

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

Assessment of penetration and permeation of caffeine by confocal Raman spectroscopy in vivo and ex vivo by tape stripping

open access: yesInternational Journal of Cosmetic Science, 2022
Tape stripping is an often‐used non‐invasive destructive method to investigate the skin penetration of a substance. In recent years, however, the suitability of confocal Raman spectroscopy (CRS) as a non‐invasive method of non‐destructive examination of ...

Cryoporometry in Femtoliter Volumes by Confocal Raman Spectroscopy [PDF]

open access: yesLangmuir, 2019
Abstract 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 ...

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 ...
