Desorption electrospray ionization mass spectrometry imaging of latent fingerprints revealed by Oil Red O

CONCLUSIONS: DESI-MS has demonstrated imaging compatibility with the application of ORO used to enhance latent fingerprints on paper and could also enable chemical profiling in natural fingermarks. In addition, MS images of ORO impurities were of higher quality than optical ones for fingerprints revealed on colored paper.PMID:38420652 | DOI:10.1002/rcm.9724
