In this work, the application of optical-photothermal infrared (O-PTIR) spectromicroscopy for the detection of highly explosive materials within fingerprints is described. High-explosive (HE) materials (e.g., PETN, RDX, C-4, or TNT) were used to prepare contaminated fingerprints. These were subsequently deposited on various objects, including microscopic glass slides, a table, a mug, etc. Samples deposited on glass slides were directly sent for analyses; for other samples, adhesive tapes were used to lift off fingermarks. In cases of difficulty in locating fingerprints, additional powders were used to enhance their visibility. Experiments were performed with a mIRage IR microscope working in a noncontact, far-field reflection mode, offering submicron IR spectroscopy and imaging. Fast imaging (several characteristic absorbances were selected for every substance of interest) was used to locate \u201csuspicious\u201d particles among various residues present in fingerprints. Subsequently, spectra were collected for those particles. Reflection mode O-PTIR spectra taken from powdered and nonenhanced fingerprints were of comparable quality to transmission mode FTIR spectra collected for pure HEs. On the basis of the performed experiments, we consider O-PTIR spectromicroscopy to open a new avenue for the nondestructive, efficient, and reliable analysis of exogenous substances deposited within fingerprints. The real significance of O-PTIR is in its ability to deliver high-quality, spatially resolved FTIR transmission-like spectra below the diffraction limit of infrared wavelengths, doing so in an easy-to-use reflection (far-field) mode. Collected spectra are also searchable and interpretable in both commercial and institutional IR databases without mathematical modeling.<\/jats:p>","DOI":"10.1021\/acs.analchem.0c00938","type":"journal-article","created":{"date-parts":[[2020,6,22]],"date-time":"2020-06-22T08:33:14Z","timestamp":1592814794000},"page":"9649-9657","source":"Crossref","is-referenced-by-count":47,"title":["Detection of High-Explosive Materials within Fingerprints\nby Means of Optical-Photothermal Infrared Spectromicroscopy"],"prefix":"10.1021","volume":"92","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6268-1081","authenticated-orcid":true,"given":"Agnieszka","family":"Banas","sequence":"first","affiliation":[{"name":"National University of Singapore , , 5 Research Link ,","place":["Singapore, 117603"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krzysztof","family":"Banas","sequence":"additional","affiliation":[{"name":"National University of Singapore , , 5 Research Link ,","place":["Singapore, 117603"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael Kwun Fung","family":"Lo","sequence":"additional","affiliation":[{"name":"Photothermal Spectroscopy Corp. , 325 Chapala Street , , ,","place":["Santa Barbara, California, United States, 93101"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustafa","family":"Kansiz","sequence":"additional","affiliation":[{"name":"Photothermal Spectroscopy Corp. , 325 Chapala Street , , ,","place":["Santa Barbara, California, United States, 93101"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shenbaga Manogara\nPandian","family":"Kalaiselvi","sequence":"additional","affiliation":[{"name":"National University of Singapore , , 5 Research Link ,","place":["Singapore, 117603"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seng Kim","family":"Lim","sequence":"additional","affiliation":[{"name":"Criminal Investigation Department , , Police Cantonment Complex 391, New Bridge Road 20-04, CID Tower Block C ,","place":["Singapore, 088762"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason","family":"Loke","sequence":"additional","affiliation":[{"name":"Criminal Investigation Department , , Police Cantonment Complex 391, New Bridge Road 20-04, CID Tower Block C ,","place":["Singapore, 088762"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark Brian Howell","family":"Breese","sequence":"additional","affiliation":[{"name":"National University of Singapore , , 5 Research Link ,","place":["Singapore, 117603"]},{"name":"National University of Singapore , , 2 Science Drive 3 ,","place":["Singapore, 117542"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2020,6,22]]},"reference":[{"key":"2026081803301869900_cit1","volume-title":"Forensic Science\nHandbook","author":"Saferstein","year":"2002","edition":"2"},{"issue":"3","key":"2026081803301869900_cit2","doi-asserted-by":"publisher","first-page":"172","DOI":"10.1016\/S0379-0738(00)00465-5","article-title":"Powder Method for Detecting\nLatent Fingerprints: A Review","volume":"120","author":"Sodhi","year":"2001","journal-title":"Forensic Sci.\nInt."},{"issue":"1\u20132","key":"2026081803301869900_cit3","doi-asserted-by":"publisher","first-page":"128","DOI":"10.1016\/j.aca.2009.06.023","article-title":"The Detection\nof Latent Fingermarks on Porous Surfaces Using Amino Acid Sensitive\nReagents: A Review","volume":"652","author":"Jelly","year":"2009","journal-title":"Anal.
