Elucidation of the effect of heat exposure on hair colored by permanent and semipermanent colorants using surface-enhanced Raman spectroscopy.
Publication Type: Academic Journal
Source(s): Journal of forensic sciences [J Forensic Sci] 2023 May; Vol. 68 (3), pp. 807-814. Date of Electronic Publication: 2023 Mar 15.
Abstract: Confirmatory identification of hair colorants can be used to establish a connection between a suspect and the crime science or demonstrate the absence of such connections. A growing body of evidence shows that surface-enhanced Raman spectroscopy (SERS)...
An application of raman spectroscopy in combination with machine learning to determine gastric cancer spectroscopy marker.
Publication Type: Academic Journal

Abstract: Background and Objective: Globally, gastric carcinoma (Gca) ranks fifth in terms of incidence and third in terms of mortality. Higher serum tumor markers (TMs) than those from healthy individuals, led to TMs clinical application as diagnostic biomarker...
Assessment of blend uniformity in a stream sampler device using Raman spectroscopy.
Publication Type: Academic Journal
Source(s): International journal of pharmaceutics [Int J Pharm] 2023 May 25; Vol. 639, pp. 122934. Date of Electronic Publication: 2023 Apr 13.
Abstract: This study describes the first implementation of Raman spectrometer in a stream sampler for the in-line monitoring of low drug concentration in poor flowability powder blends. Raman spectra were continuously acquired as the powder blends flowed through...
Quantitative analysis of low content polymorphic impurities in canagliflozin tablets by PXRD, NIR, ATR-FITR and Raman solid-state analysis techniques combined with stoichiometry.
