This pilot study found that prebleaching either virgin or previously colored hair only slightly affects the SERS spectra of dyes applied afterward, without impacting the accuracy of dye identification, supporting the technique's robustness for forensic analysis of hair dyes.

This study suggests that keratin peptide signatures in human hair shafts may potentially be used to distinguish gender and ethnicity, although further validation with larger samples is needed.

This study suggests that keratin peptide signatures from human hair shafts could potentially distinguish gender and ethnicity, though confirmation in larger studies is needed.

This study demonstrated that CD anisotropy effectively distinguishes between two polymorphs of finasteride with nearly identical electronic circular dichroism spectra, using imaging and simulated spectra to uncover unique signatures that traditional methods miss.

This study used theoretical calculations to show that phosphates strongly bind to cerium dioxide surfaces in various stable configurations, with spectral signatures identifiable in the infrared and Raman spectra, informing future experimental efforts in controlling the enzymatic activity of ceria nanoparticles.
