Characterization of Human Ovarian Teratoma Hair Using AFM, FT-IR, and Raman Spectroscopy

research Characterization of human ovarian teratoma hair by using AFM, FT‐IR, and Raman spectroscopy

3 citations , April 2011 in “Microscopy research and technique”

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

research The analysis of scalp irritation by coacervates produced in hair shampoo via FTIR with focal plane array detector, X‐ray photoelectron microscopy and HaCaT cells

5 citations , August 2016 in “International Journal of Cosmetic Science”

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

research FTIR spectroscopic and multivariate analysis for sample discrimination and adulteration detection of ulin seed (Eusideroxylon zwageri Teijsm. & Binn.) oil

July 2026 in “Pharmaciana”

This study found that the optimal characteristics for ulin seed oil extraction are fresh, mature, and resinous seeds, and that FTIR spectrophotometry with PCA can effectively detect adulteration of the oil, particularly at certain wavenumbers like 1745 cm⁻¹.

research Analysis of cosmetic residues on a single human hair by ATR FT-IR microspectroscopy

32 citations , February 2018 in “Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy”

This study successfully used ATR FT-IR spectroscopy to uniquely identify or differentiate human hairs by detecting specific spectral features associated with individual hair characteristics and cosmetic residues on hair surfaces.

research Serum-Based Assessment of Alopecia Areata Response to Treatment Using ATR-FTIR Spectroscopy

2 citations , May 2025 in “Diagnostics”

This study found that ATR-FTIR spectroscopy combined with machine learning effectively differentiated alopecia areata patients from healthy controls with an AUC of 0.85, and also showed promise in predicting treatment response, particularly through alterations in the Amide I band.
